8-bit Bits (the 1s and 0s of computer code) determine the detail in each pixel of a digitized image. The more bits, the more color possibilities available for your image. A higher bit count results in a perceived better image quality - smoother gradients (transitions between colors) and deeper shadows. 8-bit is lower quality than 12-, 14- or 16-bit, but can be digitally changed in image editing software. |
A
Abrasion test The act of putting or exposing a material against the elements in order to determine their resistance to scratching under a specified set of conditions. Materials can include metals, composites, ceramics or thick spray coatings (such as the matte UV coatings sprayed on printed canvas). Fabrics are also put under abrasion test as well, to observe their durability, resistance and wear. |
Abstract art An art style that avoids realistic and recognizable imagery, and instead depicts emotion through compositions of color and shape. Abstract art began to shift to the mainstream around the turn of the 20th century, as artists sought new ways to express their interpretations of the world. |
![Abstract art](/images/glossary/abstract_art.jpg) |
Acid-free Paper materials with a pH of around 7 are considered to be acid-free. These materials are less likely to harm artwork over time. Materials with a pH below 6.5 or above a pH of 8.5 are not considered acid-free. |
![Acid-free](/images/glossary/acid_free.jpg) |
Alignment Marks Alignment marks, also known as registration marks, are visual indicators used in the printing process to ensure accurate and consistent positioning of multiple layers or colors. These marks are typically small, easily identifiable symbols or targets placed strategically on each layer of the artwork. By aligning these marks during the printing process, printers can ensure that each color or layer lines up correctly, preventing misalignment or offsetting issues that could affect the quality of the final print. Printers use alignment marks strategically placed on each layer of the artwork to ensure perfect registration, enabling the accurate superimposition of colors and layers in the Giclée printing process. |
Alkaline Paper A pH neutral paper that is generally processed with calcium carbonate, the alkaline substance most commonly used in art production. Alkaline papers are acid-free and conservation-grade. |
Allover Painting An artwork in which the entire surface is painted from corner to corner, with no one section receiving more attention or significance. Many of Jackson Pollock's Abstract Expressionism paintings can be defined as such. |
Aluminyzed Prints Aluminyze prints are images infused directly into a sheet of aluminium using a hot press - a process called sublimation. The result? A vibrant and durable print with unparalleled colour and depth. |
Analog Printing Analog printing in the context of Giclée refers to traditional printing methods that utilize physical processes, such as lithography or screen printing, to transfer an image onto a substrate. Unlike digital printing, which involves the direct reproduction of digital files, analog printing relies on mechanical or chemical means to create prints. While digital printing offers precise control and flexibility, analog printing methods often provide unique textures and characteristics that appeal to artists and collectors seeking a more tactile and artisanal aesthetic. |
ANSI The American National Standards Institute. This national group determines the guidelines governing a wide variety of commercially produced goods. |
Anti-Aliasing Anti-aliasing is a digital image processing technique used in Giclée printing to reduce the appearance of jagged or stair-stepped edges (aliasing) in computer-generated graphics or text. By smoothing out these edges through the blending of adjacent pixels, anti-aliasing creates a more natural and visually pleasing appearance, especially when images are scaled or displayed at different resolutions. This technique helps to maintain the smoothness and clarity of fine details in Giclée prints, resulting in crisp, high-quality reproductions of digital artwork. |
Anti-Glare Coating An anti-glare coating is a specialized finish applied to the surface of Giclée prints to reduce glare and reflections, improving their visibility and readability under various lighting conditions. This coating typically consists of a microscopically textured layer that diffuses incoming light, minimizing specular reflections and glare without significantly affecting the color or sharpness of the printed image. Anti-glare coatings are especially beneficial for artworks displayed in brightly lit environments or areas with direct sunlight, enhancing the viewing experience and ensuring that the details of the print remain clear and visible. |
Anti-Reflective Coating An anti-reflective coating is a thin, transparent layer applied to the surface of Giclée prints to minimize reflections and glare. Unlike anti-glare coatings, which diffuse light to reduce glare, anti-reflective coatings work by altering the refractive index of the surface, allowing more light to pass through and less to be reflected. This results in improved clarity and visibility of the printed image, particularly when viewing from different angles or under bright lighting conditions. |
Aqueous-Based Printers Aqueous-based printers, so called because the ink used is primarily water mixed with either dyes or pigments, are widely used for canvas printing and typically offer the best image quality.
Most print shops have moved to pigmented inks because these inks provide a more urable print than dye inks; pigmented inks are now the standard. |
Archival Archival framing means that all the materials involved in the process are completely acid-free. Your artwork is framed to last.
An original artwork can be considered archival if no irreversible treatments (such as lamination or dry mounting) are applied, and the framing products involved are of archival quality. |
Archival Ink Pigment inks designed for longevity. These inks resist fading and produce conservation-grade prints that will last for decades. |
Archival Products Any professional-grade fine art paper, mat board, backing or acrylic that is acid-free and constructed to maintain its color and condition, and protect the artwork, for approximately 100 years. |
Archival-stub Framing materials designed to keep artwork undamaged and intact for as long as it is displayed (as many as 100 years), under moderate circumstances. Also called conservation-grade or museum-grade. |
Art Paper Art paper refers to a high-quality, archival-grade paper specifically designed for Giclée printing and fine art reproductions. These papers are typically made from acid-free or cotton rag materials, which ensures longevity and prevents yellowing or deterioration over time. Art papers come in various weights, textures, and finishes to suit different artistic preferences and printing requirements, offering options such as smooth matte, textured watercolor, or glossy surfaces to enhance the visual impact of the printed artwork. |
Artist Canvas Any canvas material intended and prepared for painting or other art mediums. Artist canvas is available on rolls, or pre-mounted on wood frames. Today, most canvas is made from cotton and linen, though hemp was common in the past. The canvas may be primed or unprimed, depending on the artists preference.

Banding Banding refers to a visual artifact that may occur in Giclée prints, characterized by noticeable bands or stripes of inconsistent color or tone across the printed image. Banding typically results from issues during the printing process, such as clogged printheads, uneven ink distribution, or insufficient resolution settings, leading to irregularities in color gradient transitions. To minimize banding and ensure smooth, uniform printing, printers employ techniques like nozzle cleaning, color calibration, and proper maintenance of equipment to achieve optimal print quality. |
Base Color In Giclée printing, the base color refers to the underlying color of the printing substrate before any ink is applied. The choice of base color can influence the appearance and characteristics of the final print, affecting factors such as color accuracy, contrast, and texture. Common base colors include white, off-white, and various shades of gray, each imparting different qualities to the printed image and contributing to the overall aesthetic effect. |
Base Paper Base paper refers to the primary substrate or material onto which the image is printed in the Giclée process. It serves as the foundation for the printed artwork, providing support, texture, and durability. Base papers for Giclée printing come in a variety of types and finishes, including matte, glossy, satin, and textured surfaces, each offering unique qualities that can enhance the visual impact and longevity of the print. |
Bevel/Bevelled Edge A sloping edge common on picture frames and linen liners. Generally, the approximately 45 degree slope begins at the top of the lip of the frame and slants in toward the artwork (see image). |
![Bevel/Bevelled Edge](/images/glossary/bevelled_edge.jpg) |
Bezel In the context of Giclée printing and display, a bezel refers to the frame or border surrounding the viewing area of a digital screen or monitor. Bezels are commonly found on devices such as computer monitors, TVs, and digital photo frames, where they serve both aesthetic and functional purposes. Bezels can vary in size, material, and design, influencing the overall appearance and usability of the device. |
Bit Depth Bit depth, also known as color depth, refers to the number of bits used to represent each pixel in a digital image. It determines the range of colors that can be reproduced in the image, with higher bit depths allowing for more shades and nuances of color. In Giclée printing, images with higher bit depths typically result in smoother gradients, better color accuracy, and finer detail reproduction, resulting in higher-quality prints with greater visual fidelity. |
Black (cmyk) In the CMYK color model used in printing, black (K) is one of the four primary ink colors, along with cyan (C), magenta (M), and yellow (Y). Black ink is used to create rich, deep shadows and textural details in printed images, enhancing contrast and definition. By combining varying amounts of cyan, magenta, yellow, and black ink, printers can achieve a wide range of grayscale tones and reproduce images with greater detail and accuracy. |
Black Point In digital imaging and printing, the black point refers to the darkest level of black that can be reproduced in an image or print. It represents the minimum intensity of black that the system or device is capable of producing. Maintaining a true black point is crucial for preserving shadow detail and contrast in printed images, ensuring that dark areas appear rich and well-defined without losing important visual information. |
Bleed Printing Bleed printing is the process of printing an image or design with bleed, where the ink extends beyond the intended trim edge of the printed piece. This technique is often used in Giclée printing to produce full-bleed prints, where the image or design seamlessly extends to the edge of the paper without any white borders. Bleed printing requires careful setup and trimming to ensure that the final prints have clean, uniform edges and maintain the integrity of the design. |
Bond Paper Originally used in preparing government bonds, this type of paper is of high quality and quite durable, generally having a paper weight of more than 50 g/m². In the printing business, this paper is used to produce important documents, or may be used as a lower-cost option to light fine art papers, for producing artistic reproductions.
Bond paper may be used to create original artworks using pen, ink, or pencil, and is sometimes made from rag pulp, which creates a stronger paper with a distinct texture. |
Borderless Printing Borderless printing is a printing method where the printed image extends all the way to the edges of the paper or substrate, without leaving any white borders. In Giclée printing, borderless printing is achieved by adjusting the printer settings to allow for full-bleed printing, ensuring that the image covers the entire printable area of the paper. This technique is commonly used to create prints with a seamless, edge-to-edge appearance, particularly for photographs, art prints, and other visually impactful designs where borders would detract from the overall presentation. |

Developer In traditional photography, a developer is a chemical solution used to process photographic film or paper, converting latent image particles into visible images. However, in the context of Giclée printing, the term "developer" typically refers to the software used to process digital images, adjust their properties, and prepare them for printing. This software allows users to fine-tune aspects such as color balance, exposure, contrast, and sharpness to optimize the appearance of the image before it is printed. |
Diasec Diasec is a registered trademark for a process used for face-mounting prints like photographs on acrylic sheets. The process was invented by Heinz Sovilla-Brulhart in 1969.
Because of the different light penetration and refraction of acrylic compared to normal glass, the colours are more brilliant and the image sharper than compared to standard glass in a picture frame. A Diasec mount is usually of a high gloss finish. Because the print is glued to the acrylic glass, the result is a completely flat mount of the image.
Process
The process aims to mount the print without air bubbles or smears. The image is face mounted and bonded to the acrylic glass with a gel silicone sealant which acts as a glue.
Normally the print is placed on a carrier at the backside. This is usually dibond, a composite plate of aluminium and plastic. Aluminium or other materials are also possible. If the print has to be backlit, translucent materials are necessary. |
Digital Image A digital image is a visual representation of an object, scene, or artwork that is captured, created, or stored in digital form. It consists of a grid of pixels, each containing color or grayscale information, arranged to form a two-dimensional picture. Digital images can be created using digital cameras, scanners, or computer graphics software and stored as digital files in various formats. They can be displayed on electronic devices, shared online, or printed using Giclée printing technology, offering versatility and flexibility for artistic expression and communication. |
Digital Printing Digital printing refers to methods of printing from a digital-based image directly to a variety of media. It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume laser or inkjet printers. Digital printing has a higher cost per page than more traditional offset printing methods, but this price is usually offset by avoiding the cost of all the technical steps required to make printing plates. It also allows for on-demand printing, short turnaround time, and even a modification of the image used for each impression. |
Digital Watermark A digital watermark is a hidden or visible marker embedded in a digital image to indicate ownership, authenticity, or copyright information. It is typically added during the image editing or printing process and can take the form of text, logos, patterns, or cryptographic codes. Digital watermarks help protect the intellectual property rights of artists and photographers by deterring unauthorized use, reproduction, or distribution of their images. In Giclée printing, digital watermarks can be incorporated into printed images to provide traceability and authentication, ensuring that prints are genuine and authorized. |
Diorama A diorama is a three-dimensional model or display that depicts a scene or landscape in miniature scale, often enclosed within a box or frame. Dioramas are commonly used in art, education, and entertainment to recreate historical events, natural environments, or fictional worlds with intricate detail and realism. In Giclée printing, dioramas can be photographed or digitally reproduced to create high-quality prints that preserve the depth, texture, and perspective of the original three-dimensional artwork. |
Dots per inch (dpi) Dots per inch (DPI) is a measurement used to describe the resolution of a digital image or the output resolution of a printing device. It represents the number of ink dots or pixels that can be printed or displayed within one linear inch of space. Higher DPI values indicate greater image detail and smoother tonal transitions, while lower DPI values result in coarser detail and visible pixilation. In Giclée printing, selecting the appropriate DPI setting is crucial for achieving sharp, high-quality prints with accurate color reproduction and fine detail. |
Double primed canvas Canvas treated with two coats of lead paint, which acts as as a barrier to prevent the artist's paint from soaking into the fabric. Double primed canvas generally has a smoother surface and is stiffer. However, due to this stiffness, it can crack along the edges when stretched.
At KeenART media, the canvas we print on is specially treated for Giclée printing.
We also offer unprimed and double-primed artist canvas for sale. |
![Double primed canvas](/images/glossary/double_primed_canvas.jpg) |
DPI DPI is a printing term that describes the number of dots per inch that are used to create an image. The higher the DPI, the higher the quality of the image. 300 DPI is sufficient for most applications. We recommend a higher DPI if you plan on resizing your images to a size larger than the original photos. |

Dye Sublimation Sublimation is a process where an image can be printed onto transfer paper using dye-based inks and then with heat and pressure become transferred into the substrate.
Dye sublimation on hard surface surfaces is possible if the surfaces have been coated. Instead of printing images directly on a surface, which may scratch easily, the image is infused into the coating to provide permanent protection and durability.
|
Dye-Based Inks Dye-based inks are liquid colorants composed of soluble dyes dissolved in a carrier liquid, such as water or glycol. These inks are commonly used in inkjet printers for their vibrant colors, wide color gamut, and smooth color transitions. Dye-based inks are known for producing prints with high color saturation and excellent image quality, particularly on glossy or coated papers. However, they may be less resistant to fading and moisture compared to pigment-based inks, making them more suitable for indoor use and short-term applications in Giclée printing. |
Dye-Sublimation Printer A dye-sublimation printer is a type of digital printing device that uses heat to transfer dye directly onto a substrate, such as paper, fabric, or plastic. The process involves printing the image onto a special transfer paper using dye-sublimation inks, then applying heat and pressure to transfer the dye onto the substrate, where it sublimates and bonds with the surface. Dye-sublimation printers are commonly used for producing high-quality, durable prints with continuous-tone images, vibrant colors, and smooth gradients, making them popular for applications such as photo printing, textile printing, and product decoration in Giclée printing. |

Edge Sharpness Edge sharpness refers to the clarity and definition of edges in a printed image, particularly in areas of high contrast or fine detail. It is influenced by factors such as printer resolution, image resolution, ink droplet size, and substrate texture. Achieving optimal edge sharpness is essential for producing prints with crisp detail, smooth transitions, and accurate reproduction of fine lines and text in Giclée printing. Proper image processing, printer calibration, and substrate selection can help improve edge sharpness and enhance overall print quality. |
Enlargement An enlargement refers to a printed image that has been reproduced at a larger size than its original dimensions. It involves scaling up the image to create a larger print while maintaining its aspect ratio and visual quality. Enlargements are commonly produced in Giclée printing by using high-resolution digital files or enlarging photographic negatives or transparencies during the printing process. Enlargements are often used in fine art, photography, and commercial printing to showcase detailed artwork, photographs, or graphics on a larger scale. |
Enlarger An enlarger is a device used in traditional darkroom photography to project and focus an image from a negative or transparency onto photosensitive paper for printing. It consists of a light source, a negative carrier, a lens system, and an adjustable height mechanism to control the size and focus of the projected image. Enlargers allow photographers and printmakers to produce prints of various sizes by adjusting the magnification and exposure settings during the printing process. Although less common in the digital age, enlargers are still used by some photographers and artists for producing analog prints and alternative printing techniques. |

EXIF Besides information about the pixels of the image, most cameras store additional information such as the date and time the image was taken, aperture, shutterspeed, ISO, and other camera settings. |
![EXIF](/images/glossary/exif.jpg) |
Exposure Compensation Exposure compensation is a camera setting that allows photographers to manually adjust the exposure settings to achieve the desired brightness or darkness in a photograph. It is typically expressed in terms of exposure value (EV) increments, with positive values indicating increased brightness (overexposure) and negative values indicating decreased brightness (underexposure).
Exposure compensation is useful in situations where the camera's automatic exposure metering may not accurately capture the desired exposure, such as high-contrast scenes or backlit subjects. In Giclée printing, exposure compensation may also be applied during the image editing process to fine-tune the exposure and optimize print quality. |
Exposure Value (EV) Exposure Value (EV) is a numerical scale that represents a combination of aperture and shutter speed settings used to achieve a specific exposure level in photography. It provides a standardized way to measure and compare different combinations of aperture and shutter speed settings. Each increment on the EV scale represents a doubling or halving of the amount of light reaching the camera sensor or film. Photographers use EV to adjust exposure settings to compensate for changes in lighting conditions or achieve creative effects while maintaining consistent exposure levels. |
F ^^Top
F-stop F-stop, also known as f-number or aperture value, is a numerical measurement that indicates the size of the aperture opening in a camera lens. It represents the ratio of the lens's focal length to the diameter of the aperture opening. Lower f-stop values indicate larger aperture openings, which allow more light to pass through the lens and reach the camera sensor or film, resulting in brighter exposures and shallower depth of field. Higher f-stop values indicate smaller aperture openings, which reduce the amount of light and increase depth of field. F-stop settings control exposure, depth of field, and image sharpness in photography. |
Face-mounted Face-mounting is a process used in fine art printing and display where a print is adhered to the back of a transparent material, such as acrylic or glass, using a clear adhesive. This creates a smooth, glossy surface on the front of the print, enhancing its visual impact, depth, and vibrancy. Face-mounted prints are valued for their modern and sleek appearance, as well as their durability and resistance to fading, moisture, and damage. Face-mounting is commonly used for displaying Giclée prints, photographs, and artwork in galleries, exhibitions, and commercial settings. |
Fade(ing) To lose or cause to lose brightness or brilliance or definition of line, form and color. |
Fading Fading refers to the gradual loss or alteration of colors, tones, or image detail in a printed or displayed image over time due to exposure to light, heat, humidity, pollutants, or other environmental factors. Fading can occur in both analog and digital prints, affecting the visual quality and longevity of the printed image.
Factors such as ink type, paper quality, display conditions, and protective coatings can influence the rate and severity of fading. To minimize fading in Giclée printing, archival-quality materials, pigment-based inks, UV-resistant coatings, and proper display techniques are often used to ensure long-lasting print durability and color stability. |
Fast Color Ink This term refers to inks that are "color fast", meaning they retain the density of their color and do not fade despite washing and excessive handling.
Depending on the ink, color fast may imply UV fade-resistant |
Feathering Feathering, also known as softening or blending, is a digital image editing technique used to create smooth and seamless transitions between adjacent areas of an image. It involves selectively blurring or blending the edges of a selection or mask to reduce or eliminate harsh transitions and create a more natural and aesthetically pleasing effect. Feathering is commonly used in techniques such as image compositing, retouching, and selective adjustments to blend elements together seamlessly and achieve professional-looking results in Giclée printing and digital photography. |
Felt Marker A felt marker, also known as a felt-tip pen or marker pen, is a writing or drawing tool with a porous tip made of compressed felt or fiber material.

High-Resolution Image High-resolution = high quality.
If an image is high-resolution, this implies it will print well at a large - or at least the desired - size, with clear, crisp detail and no pixelation.
There is no single determination of high resolution. The size of the digital image must be comparable to the desired print size, but the quality must be good as well. For instance, a high ppi or dpi (pixels or dots per inch) but a small image (300x300 pixels) will not print well at any size.
However, a large size (3000x3000 pixels) and good dpi (300) does not guarantee quality either - the image could simply have been changed to these quantities with no regard for image quality, resulting in heavily pixelation (clusters of visible squares instead of a smooth image).
Ideally, the customer should confirm with the designer that their image is the appropriate resolution or quality for the print size. |
High-Resolution Scan A good quality digital image created from copying the artwork using a flatbed scanner. This is achieved by scanning the entire image at one time, or ensuring even light distribution when scanning multiple sections.
We can create a high-resolution digital images from any original artwork. View our artwork scanning services and place your order today. |
Highlight Detail Highlight detail refers to the level of detail present in the brightest areas of an image, particularly in highlight regions where light is reflected or emitted at its highest intensity. Maintaining detail in highlights is important for preserving texture, structure, and tonal variation in bright areas of the image. Overexposure or clipping of highlights can result in loss of detail, causing highlights to appear washed out or lacking in texture. Techniques such as exposure adjustment, highlight recovery, and careful exposure metering can help preserve highlight detail in photography. |
Highlights and Shadows Highlights and shadows are the two primary components of contrast in an image, representing the brightest and darkest areas, respectively. Highlights are the areas where light is reflected or emitted at its highest intensity, while shadows are the areas where light is blocked or absorbed, resulting in reduced illumination. The interplay between highlights and shadows creates depth, dimension, and visual interest in an image, defining the shape, form, and texture of objects. Properly balancing highlights and shadows is essential for achieving a well-exposed and visually appealing image with a full range of tonal values. |
Hinge Mounting Hinge mounting is a method of mounting artworks or prints for display or framing using hinges attached to the back of the artwork and a mat or backing board. Hinge mounting allows the artwork to be secured in place without directly adhering it to the mounting surface, providing flexibility and protection against damage. The hinges are typically made of archival-quality materials, such as Japanese paper or linen tape, and are attached to the back of the artwork using archival adhesive or paste. Hinge mounting is commonly used for mounting delicate or valuable artworks, prints, photographs, and documents for display or preservation. |
Hinging The process of adhering artwork to a backing or mounting board. Acid-free tape is attached to the top of the work and another strip is placed over the top to secure it on both surfaces. Try to hinge only from the top so the artwork is able to hang freely. This helps prevent the piece from buckling, as it enables the different components — artwork, frame, mat, mounting board, etc. — to expand and contract at their own rates with the temperature and humidity. |
Hot lamination Lamination is a process of permanently applying a clear plastic coating to paper. In hot lamination, the cover\'s adhesive is activated by heat. When inserted into the laminator, the clear cover is melted onto and around the paper, completely enclosing it in a protective casing. Hot lamination produces a product more resistant to wear and tear than cold lamination.
We offer three types of large format lamination as part of our dry mounting service. |
Hue A color or shade. For example: Blue, grey, maroon. |
Hue Shift Hue shift, also known as color shift, refers to a change in the perceived color of an object or image due to alterations in lighting conditions, color reproduction, or color management. Hue shift can occur when viewing an image under different lighting sources with varying color temperatures, such as natural daylight, incandescent light, or fluorescent light, which may cause colors to appear warmer or cooler than they actually are.
Hue shift can also occur during image processing or printing when colors are inaccurately reproduced or adjusted, resulting in shifts in hue or color balance. Managing hue shifts is important for achieving accurate color reproduction and consistency in photography, printing, and digital imaging workflows. |

ICC International Colour Consortium |
![ICC](/images/glossary/4) |
ICC Profile An ICC profile, short for International Color Consortium profile, is a standardized data file that describes the color characteristics of a device, such as a monitor, printer, or digital camera. ICC profiles define how colors are represented and reproduced by a device, including color gamut, color temperature, and color response. By using ICC profiles, color management systems can ensure consistent and accurate color reproduction across different devices and software applications. In Giclée printing, ICC profiles are used to calibrate printers and ensure that prints accurately match the colors of the original digital image. |
Illustrator An Adobe program used to edit digital vector images. It can create original vector images (images created using geometric shapes - lines, curves, polygons) or edit existing vectors.
Illustrator is commonly used for graphic design, animation and typography. |
Image Alignment Image alignment is the process of adjusting the position and orientation of multiple images to achieve precise registration and alignment between them. Image alignment is essential in various imaging workflows, including panoramic photography, image stitching, and compositing, where multiple images need to be seamlessly combined or overlaid. Alignment techniques may involve matching key features or control points in the images, applying geometric transformations such as translation, rotation, and scaling, or using specialized software algorithms to automatically align images based on visual similarities. |
Image Capture Image capture refers to the process of capturing or acquiring digital images using a digital camera, scanner, or other imaging device. During image capture, light from the scene is converted into digital data by sensors in the imaging device, creating a digital representation of the subject or scene. Image capture parameters such as exposure, aperture, shutter speed, ISO sensitivity, and white balance settings influence the quality, brightness, color accuracy, and detail of the captured images. In Giclée printing, high-quality image capture is essential for producing digital files with sufficient resolution, color fidelity, and detail for printing. |
Image Carrier An image carrier is a substrate or material on which an image is printed or transferred. In Giclée printing, common image carriers include paper, canvas, fabric, metal, and specialty media. The choice of image carrier depends on factors such as the desired print size, surface texture, finish, and intended use of the final print. Different image carriers can affect the appearance, texture, durability, and archival properties of the printed image. Giclée printers are capable of printing on a wide range of image carriers, allowing artists and printmakers to choose the most suitable substrate for their artistic vision and printing requirements. |
Image Reversal Image reversal is a photographic or printing process in which the tones or colors of an image are reversed, resulting in a negative image that is the inverse of the original. Image reversal techniques can be achieved through various methods, such as chemical processing, digital manipulation, or printing processes. In traditional photography, image reversal occurs during the development of negative film or reversal film, where the exposed image is processed to produce a positive image. In digital imaging, image reversal can be achieved through software manipulation or printing techniques to create artistic effects or experimental visuals. |
Image Sensor An image sensor is an electronic device used in digital cameras and other imaging devices to capture and convert optical images into digital signals. It is a crucial component that serves as the "eye" of the camera, detecting light and converting it into electrical signals that can be processed and stored as digital image files. Image sensors are typically composed of millions of individual photosensitive pixels arranged in a grid pattern.
The two most common types of image sensors used in digital cameras are CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide Semiconductor). CCD sensors use a series of capacitors to capture and transfer charge from each pixel, while CMOS sensors utilize transistors to convert light into electrical signals directly. Image sensors vary in size, resolution, sensitivity to light, and dynamic range, influencing the overall image quality and performance of digital cameras. |
Image Stabilization Image stabilization is a technology used in digital cameras, lenses, and other imaging devices to reduce the effects of camera shake and motion blur in photographs and videos. It compensates for involuntary camera movements caused by hand-held shooting, windy conditions, or other factors that can lead to blurry images. Image stabilization systems typically employ optical or sensor-based mechanisms to detect and counteract camera shake in real-time, allowing for sharper and more stable images.
Optical image stabilization (OIS) involves moving lens elements or sensor components to compensate for camera movement, while sensor-shift image stabilization (IBIS) physically shifts the image sensor within the camera body to achieve similar stabilization effects. Some cameras and lenses feature hybrid stabilization systems that combine both optical and sensor-based methods for optimal performance. Image stabilization technology is particularly beneficial in low-light conditions, telephoto photography, and video recording, where camera shake and motion blur are more pronounced. |
Imposition One of the fundamental steps in the prepress printing process. It consists of the arrangement of the printed product’s pages on the printer’s sheet, in order to obtain faster printing, simplify binding and reduce paper waste.
Correct imposition minimizes printing time by maximizing the number of pages per impression, reducing cost of press time and materials. To achieve this, the printed sheet must be filled as fully as possible. |
Indigo Ink An inkjet ink composed of charged pigment in a carrier liquid. This allows the spraying of extremely fine particles, for images at very high resolution (up to 2400 dots per inch). |
Ink An ink is a liquid containing various pigments and/or dyes used for coloring a surface to produce an image or text. |
![Ink](/images/glossary/ink.jpg) |
Ink Adhesion Ink adhesion refers to the ability of printing inks to adhere to the surface of a printing substrate, such as paper, cardboard, plastic, or metal, without smudging, smearing, or flaking off. Proper ink adhesion is essential for producing high-quality prints with vibrant colors, sharp detail, and long-lasting durability. Factors that influence ink adhesion include the surface properties of the substrate (such as porosity, texture, and coating), ink formulation (such as viscosity, drying time, and pigment dispersion), and printing conditions (such as temperature, humidity, and pressure). |
Ink and print fading time To lose or cause to lose brightness or brilliance. The fading time of ink jet ink is a direct result of the inks that you choose, as well as the environment where the print is displayed. All dye-based inks fade noticeably under direct sunlight and in interior applications where direct sunlight may fall on the image, and/or, where fluorescent or other UV lighting is present. Although the fading process is inherent in all ink jet inks, certain UV enhanced inks, pigment-based inks, and UV inhibiting coatings will extend the longevity of ink color. |
Inkjet Canvas Artist canvas that is specially coated to be printed on using an inkjet printer. The type of coating used will vary from brand to brand, but can result in a canvas that is water-resistant, fast-drying, and/or acid-free (conservation-grade). Additionally, the coatings must be flexible, as canvas prints are generally stretched over a wooden frame.
There are 100% cotton and poly-cotton inkjet canvases available. 100% cotton has a richer texture, but the color can vary along the roll. Poly-cotton canvas is very consistent from print to print, but may have less texture. |
![Inkjet Canvas](/images/glossary/inkjet_canvas.jpg) |
Inkjet printer Inkjet printers are a type of computer printer that operate by propelling tiny droplets of liquid ink onto paper. They are the most common type of computer printer for the general consumer due to their low cost, high quality output, ability to print in vivid color, and ease of use.
At KeenART Media, all our canvas prints and fine art prints are created using a top-quality inkjet printer. |

Lamination Lamination is a process of bonding thin layers of material together to create a composite structure with improved strength, durability, and surface properties. In printing and graphic arts, lamination involves applying a thin layer of clear plastic film, such as polyester or polypropylene, to the surface of printed materials using heat and pressure. Lamination protects printed materials from moisture, abrasion, UV radiation, and other environmental factors, extending their lifespan and enhancing their appearance. Laminated prints are commonly used for outdoor signage, banners, posters, menus, ID cards, and other applications requiring durability and weather resistance. |
Landscape Orientation Refers to the angle at which the framed or canvas image is hung. Landscape oriented images are those displayed lengthwise, so that the top edge (parallel to the floor) is the long dimension of the painting, and the side edge is the short dimension.
Also referred to as "horizontal orientation".
The opposite of "portrait orientation". |

Laser Engraving Laser engraving is a versatile and precise method of creating deep, permanent marks, patterns, or designs on a variety of materials, including metals, plastics, wood, leather, glass, and stone. In laser engraving, the focused laser beam interacts with the material's surface, removing material through ablation or vaporization to create recessed or raised areas with high resolution and detail.
Laser engraving offers advantages such as high speed, accuracy, repeatability, and the ability to produce intricate designs, text, logos, and images with sharp edges and fine details. Laser engraving is used in various industries and applications, including awards and trophies, signage, jewelry, woodworking, personalized gifts, architectural models, and industrial part marking. Laser engraving systems may employ different laser sources, including CO2 lasers, fiber lasers, and diode lasers, each offering specific advantages in terms of wavelength, power, and material compatibility for different engraving applications. |
Latex Ink A relatively new type of inkjet ink,offered as an alternative to solvent inks. A water carrier is mixed with a polymer dye, which is then applied to the substrate using heat. Unlike traditional solvent inks, latex inks are odorless, which eliminates ventilation issues. |
Lens A lens is a transparent optical component or device that refracts or bends light rays passing through it, focusing or diverging them to form an image. Lenses are essential elements in optical systems, cameras, telescopes, microscopes, eyeglasses, and other imaging devices, where they play a crucial role in magnifying, magnifying, and manipulating light to capture, project, or view images.
Lenses can be made from various materials, such as glass, plastic, and crystalline substances, and come in different shapes, sizes, and configurations, including convex lenses, concave lenses, cylindrical lenses, and aspherical lenses. Lenses exhibit properties such as focal length, optical power, aberrations, and aperture size, which determine their optical performance and imaging characteristics. By controlling the curvature and thickness of the lens surfaces, designers can achieve precise control over the focusing, resolution, and distortion of images in optical systems. |
Lens Flare Lens flare is a visual phenomenon characterized by unwanted artifacts or patterns of light that appear in an image as a result of light sources hitting the camera lens at oblique angles. Lens flare can manifest as streaks, circles, or geometric shapes of varying intensity and color, depending on the characteristics of the lens, the angle of the light source, and the position of the camera. Lens flare is caused by internal reflections and scattering of light within the lens elements, particularly when shooting towards bright light sources such as the sun or artificial light sources.
While lens flare is often considered a technical flaw and may detract from the overall image quality, it can also be used creatively to add visual interest, mood, and atmosphere to a photograph. Some photographers intentionally incorporate lens flare into their compositions to create artistic effects or evoke a sense of warmth, nostalgia, or drama. Lens hoods and lens coatings are commonly used to minimize or prevent lens flare by reducing the amount of stray light entering the lens and improving contrast and color saturation in images. |
Lens Hood A lens hood is a cylindrical or conical accessory that attaches to the front of a camera lens to block unwanted light from entering the lens and causing lens flare, ghosting, or reduced contrast in images. Lens hoods are designed to extend beyond the front element of the lens, shading it from direct sunlight, stray light, and other sources of glare.
By preventing extraneous light from hitting the lens at oblique angles, lens hoods help maintain optimal image quality, color saturation, and contrast, especially in bright outdoor conditions or when shooting towards the sun. Lens hoods come in various shapes and sizes to match specific lens designs and focal lengths. Some lens hoods are reversible or collapsible for compact storage when not in use. While lens hoods are primarily used to improve image quality, they also provide physical protection for the front lens element against accidental bumps, scratches, and damage. |
Lens Mount A lens mount refers to the mechanical interface and attachment mechanism used to connect a camera lens to a camera body. Lens mounts vary depending on the camera system and manufacturer, with each mount design featuring specific dimensions, alignment pins, and electronic contacts for communication between the lens and camera body. Common lens mount systems include Canon EF, Nikon F, Sony E, Fujifilm X, and Micro Four Thirds, among others.
Each lens mount is designed to ensure precise alignment and secure attachment of the lens to the camera body, enabling proper focusing, aperture control, and communication of lens data and metadata. Lens mounts may also support features such as autofocus, image stabilization, and electronic lens control, depending on the compatibility and specifications of the camera and lens system. |
Lens Speed Lens speed, also known as lens aperture or lens brightness, refers to the maximum aperture diameter of a camera lens, expressed as a numerical f-stop value. A lens with a larger maximum aperture (smaller f-stop number) is considered "faster" because it allows more light to pass through the lens to the camera sensor, enabling faster shutter speeds and better performance in low-light conditions.
Fast lenses are desirable for situations where capturing fast-moving subjects, achieving shallow depth of field, or shooting in dimly lit environments is required. The speed of a lens is determined by its maximum aperture size relative to the focal length of the lens. For example, a lens with a maximum aperture of f/2.8 is considered faster than a lens with a maximum aperture of f/4.0. Fast lenses are commonly used in portrait photography, sports photography, and photojournalism, where the ability to capture sharp, well-exposed images in challenging lighting conditions is essential. |
Limited Edition In printmaking, multiples of a print struck from the same plate may be limited to a certain number of copies. This also refers to other forms of published artwork that are identical, usually published at the same time, and limited to a quoted number. For prints, edition numbers are conventionally marked in pencil using fraction format: the bottom number indicates the total number of prints in the edition, and the top number indicates the order in which the print was signed. The publisher undertakes not to produce more than edition size. The smaller the edition size, the more rare the print, and hence the higher the potential value. Edition sizes range from an edition of 2 to thousands. In practice, editions of more than 750 prints have little, if any, extra value. |
![Limited Edition](/images/glossary/limited_edition.jpg) |
Limited Edition Print When an artist prints a run of the same image, they determine how many of that image are to be printed. If they choose to print only 100, or 1000 copies of one image, it is limited edition. Each print will usually feature the print number (34/100) and the artist's signature. The more exclusive the piece (the fewer prints), the more expensive and valuable. |
Linen Canvas Artist's canvas is make from a variety of fabrics. Linen and cotton are the most common.
Linen is more expensive. It is longer lasting, due in part to the oils retained in the canvas that keep it pliable, and less likely to expand, due to the equally weighted threads used to construct the canvas. |
Liner A frame molding used within the outer molding/picture frame, sometimes called a "linen liner" or "insert". The may be covered with fabric, such as velvet or linen. Many liners are made from fully finished frame stock, including gold or silver. The liner serves the same purpose as a mat: to provide a distraction-free space between the art and the frame, and enhance the artwork.
Liners are paired with stretched and mounted canvas prints or paintings, and do not require a clear glass or acrylic cover. A liner may also be used on large, glass-covered artwork, as the largest mat size available is 32x40". If it is more than 2 1/2 inches wide, it is called a "panel". ![](/images/picture-frame-liner-insert.jpg)

Linocut Linocut is a printmaking technique in which a design is carved into the surface of a linoleum block using cutting tools, leaving raised areas that will receive ink for printing. The linoleum block is then inked with a roller, and paper is pressed onto the block to transfer the inked design onto the paper. Linocut prints are characterized by their bold lines, textures, and graphic quality, resulting from the relief surface of the linoleum block. Artists can create multiple prints from a single linoleum block, varying the colors, papers, and printing techniques to achieve different effects. Linocut is a versatile and accessible printmaking technique popular among artists, illustrators, and printmakers for its expressive potential and tactile qualities. |
Lithograph A copy of a work that is created by the artist himself (ie: not a print created years later from a digital image).
The artist creates a mirror image of the artwork using grease pencils on stone. Oil-based ink is then applied to the piece, and bonds with the grease but avoids the uncolored areas. Canvas or paper is then laid over the plate and pressed to transfer the ink onto the material. The plate is then re-inked for the next sheet of material. |
Lithography The process of producing a picture, writing, or the like, on a flat, specially prepared stone, with some greasy or oily substance, and of taking ink impressions from this as in ordinary printing.
It was invented in 1796 by German author Alois Senefelder as a cheap method of publishing theatrical works. Lithography can be used to print text or artwork onto paper or other suitable material. |
Luminance Luminance refers to the brightness or intensity of light emitted or reflected from a surface, as perceived by the human eye. In digital imaging and color science, luminance is one of the components of color representation, along with chrominance. Luminance represents the black-and-white information or brightness values in an image, while chrominance represents the color information or hue and saturation values.
Luminance is often measured in units such as candelas per square meter (cd/m²) or relative values on a scale from 0 to 100, with 0 representing absolute black and 100 representing the brightest white. In digital imaging, luminance values are typically represented in grayscale images or luminance channels of color images, where variations in luminance contribute to contrast, tonal range, and overall image brightness. |
Lustre Finish A semi-glossy finish that reflects light without compromising the image with a visible reflection. |

Magenta Magenta is a primary color in the subtractive color model, along with cyan and yellow. Magenta is one of the three primary colors used in color printing and reproduction processes, such as CMYK printing, where it serves as one of the ink colors used to create a wide range of colors and hues. Magenta is a purplish-red color with a dominant hue that lies between red and blue on the color wheel. Magenta is commonly used in color printing to reproduce a variety of colors, including reds, purples, pinks, and blues, by mixing different combinations of cyan, magenta, yellow, and black inks or toners. |
Masking tape A pressure sensitive, self adhesive that is easy to tear and generally cream or white in color. It is available in various widths and is popular for protecting areas adjacent to those to be painted, due to its ease of removal. Various strengths are available, and are rated 1-100 based on the adhesion.

Matte Finish A non-glossy, "flat" finish that creates an even reflective surface with no glare. Matte paper is generally smooth in texture. |
Megapixel A megapixel is a unit of measurement used to quantify the resolution of digital images, representing one million pixels. It is commonly used to describe the resolution capability of digital cameras, camera sensors, and digital displays. The number of megapixels in an image indicates the total number of individual pixels that compose the image, with higher megapixel counts corresponding to higher image resolutions and potential for finer detail and larger print sizes.
For example, an image captured by a camera with a resolution of 12 megapixels contains approximately 12 million pixels, while an image captured by a camera with a resolution of 24 megapixels contains approximately 24 million pixels. The megapixel count alone does not determine image quality, as factors such as sensor size, pixel size, lens quality, and image processing also play significant roles. However, higher megapixel counts generally allow for greater flexibility in cropping, printing large-format images, and capturing finer details, particularly in situations where high-resolution output is desired. |
Memory Card A memory card is a portable storage device used to store digital data, such as photographs, videos, audio files, and documents. Memory cards are commonly used in digital cameras, camcorders, smartphones, tablets, and other electronic devices that require removable storage for capturing and storing multimedia content. Memory cards come in various formats and capacities, including Secure Digital (SD), CompactFlash (CF), microSD, Memory Stick, and others, each with its own physical size, storage capacity, and data transfer speed.
The storage capacity of memory cards ranges from a few gigabytes to several terabytes, allowing users to store thousands of photos, hours of video footage, and large data files. Memory cards are designed to be durable, shock-resistant, and capable of withstanding extreme temperatures and environmental conditions, making them suitable for use in demanding situations such as outdoor photography, sports photography, and professional videography. When choosing a memory card, factors to consider include storage capacity, data transfer speed, compatibility with the device, and reliability for long-term storage and data retention. Regular backup and proper handling of memory cards are essential to prevent data loss and ensure the integrity of stored digital content. |
Metallic Paper Metallic paper is a type of printing paper with a metallic or pearlescent finish that imparts a subtle shimmer or metallic sheen to printed images. Metallic paper is coated with metallic pigments or reflective layers that enhance color saturation, contrast, and luminosity, giving images a unique, three-dimensional appearance with depth and vibrancy. Metallic paper is commonly used for high-end photography, fine art prints, luxury packaging, greeting cards, and marketing materials to create eye-catching, premium-quality reproductions. Metallic paper is available in various weights, surface textures, and finishes to suit different printing techniques and applications. |
Moiré Pattern A moiré pattern is an interference pattern that occurs when two sets of repetitive patterns, such as lines, grids, or textures, overlap or are slightly out of alignment with each other. Moiré patterns manifest as unwanted visual artifacts or shimmering effects in digital images, caused by the interaction between the repeating patterns in the subject and the grid-like arrangement of pixels on the camera sensor. Moiré patterns are more likely to occur when photographing subjects with fine, high-frequency textures or patterns, such as textiles, screens, or architectural details.
The appearance of moiré patterns can be minimized by adjusting the shooting angle, changing the distance from the subject, or using anti-aliasing filters in front of the camera sensor to blur fine details and reduce interference patterns. In post-processing, moiré patterns can be corrected using specialized software tools or by applying selective blurring or sharpening techniques to affected areas of the image. Understanding the causes and characteristics of moiré patterns is important for photographers to minimize their occurrence and preserve image quality in digital photography. |
Monochrome Monochrome refers to images that are composed of varying shades of a single color, typically black, white, or grayscale. In photography, monochrome images lack color information and are represented solely by variations in brightness and contrast. Monochrome photography emphasizes shape, form, texture, and tonality, allowing photographers to convey mood, atmosphere, and emotion through the interplay of light and shadow.
Common techniques for creating monochrome images include converting color photographs to grayscale or shooting with black-and-white film. Monochrome images often evoke a timeless and classic aesthetic, and they are widely used in fine art photography, portrait photography, street photography, and documentary photography to capture the essence of a subject without the distraction of color. |
Mottle Mottle refers to an uneven distribution or irregular pattern of color, tone, or texture in a surface or material, resulting in blotchy or speckled appearance. Mottling can occur naturally in organic materials, such as wood, stone, or marble, due to variations in grain, density, or mineral content. In printing and reproduction processes, mottling can occur when ink or pigment is inconsistently applied or absorbed by the substrate, resulting in areas of uneven color or density. Mottling can also occur in digital imaging due to compression artifacts, noise, or interpolation errors. In some cases, mottling may be intentional and used for artistic effect, while in others, it may be undesirable and corrected through adjustments in printing or image processing. |
Mounting Mounting refers to the process of attaching or securing a print, artwork, photograph, or other two-dimensional object onto a backing board, mat, frame, or display surface for presentation, protection, or preservation. Mounting techniques vary depending on the size, weight, and characteristics of the object being mounted, as well as the desired display method and aesthetic preferences.
Common mounting methods include dry mounting (using adhesives or heat to bond the print to a backing board), hinge mounting (attaching the print to a mat or backing board using archival hinges), float mounting (suspending the print within a frame or display case), and pressure-sensitive mounting (using adhesive sheets or tapes to adhere the print to a substrate). Proper mounting ensures that prints are securely held in place, flat, and protected from damage or deterioration over time. |
Museum Wrap While "gallery wrap" refers simply to the process of wrapping a canvas all the way around the stretcher bar frame and affixing it to the back, "Museum wrap" refers to the color on the drop edges (sides) of the canvas). In a museum wrap, the entire image is confined to the front of the canvas, and the sides are a solid color or white. This may be due to canvases in museums and galleries generally being frames, so the edges were never visible.
There appears to be some disagreement about whether museum wrap is limited to canvases wrapped on 1 1/2" in stretcher bars, or if the depth of the bar does not matter for the designation. |

Nail-less hangers Any hanger or hook that does not require a nail to affix it to the frame or wall.
(1) sawtooth hangers generally have a pointed tip on each end that can be pressed or hammered into the top back of the frame. A nail or other hook is required to hang it on the wall, however.
(2) Adhesive hangers are popular today, and are comprised of a flat, double-sided adhesive that affixes the hanger to the wall. When the hanger needs to be removed, a tab attached to the adhesive is pulled, and the entire piece comes off without ruining the wall.
(3) A hanger with sharp teeth that can be pressed or hammered into the wall. The face is then flush with the wall, providing a jutting hook on which to hang the artwork. |
![Nail-less hangers](/images/glossary/nailless_hangers.jpg) |
Negative A negative is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest. This reversed order occurs because the extremely light-sensitive chemicals a camera film must use to capture an image quickly enough for ordinary picture-taking are darkened, rather than bleached, by exposure to light and subsequent photographic processing. |
Noise Reduction Noise reduction is the process of minimizing or eliminating unwanted noise from digital images to improve overall image quality and clarity. In digital photography, noise reduction techniques are used to reduce the visibility of noise artifacts, such as grain or speckles, caused by factors such as high ISO sensitivity, low-light conditions, or limitations in the camera's image sensor. Noise reduction algorithms analyze the pixel data in an image and apply smoothing or averaging techniques to suppress noise while preserving image detail and sharpness.
Many digital cameras feature built-in noise reduction settings that automatically apply noise reduction processing to images during capture, while advanced image editing software also offers noise reduction tools that allow photographers to fine-tune noise reduction parameters during post-processing. When applying noise reduction, it's important to strike a balance between noise reduction and image sharpness, as excessive noise reduction can result in loss of detail and a "plastic" appearance in the final image. Photographers should experiment with different noise reduction settings and techniques to achieve the desired balance between noise reduction and image quality in their photographs. |
Non-Glare Glass Glass where one or both surfaces have been treated chemically or mechanically to slightly roughen the surface, causing reflected incident light to be dispersed in all directions. Because the glass surface is not smooth, art images behind the glass tend to be softened. The softness depends on how far the art is from the glass. No more than two or three mats are recommended to be used with non-glare glass. If clarity is desired, objects in deep frames (shadow boxes) should not be displayed with non-glare glass. |

OBA Optical brightening agents.
A class of chemicals that absorb light energy in one spectrum and emit it in another. When applied to white paper, an OBA can lessen a yellowed appearance. Also called "fluorescent lightening agents", it is applied to some fine art papers to create the bright white often desired. Whether or not OBAs have an archival lifespan is still contested. |
Offset Clips Used to affix a stretched canvas to a frame. Also known as a “Z bracket”, this stepped metal hardware has a hole in either end through which a screw or nail is driven. One end of the bracket is fastened to the stretcher bar frame, the other to the back of the picture frame. Offset clips allow for artwork that is slightly larger or smaller than the depth of the frame rabbet to be fitted. They are also used to attach a canvas to a floater frame.

![Offset Clips](/images/glossary/offset_clips.jpg) |
Offset Printing Offset printing, also known as offset lithography, is a widely used printing technique in which ink is transferred from a printing plate to a rubber blanket cylinder and then onto the printing substrate, typically paper. Offset printing is based on the principle of oil and water repulsion, where the image areas on the printing plate attract ink, while the non-image areas repel ink.
Offset printing is capable of producing high-quality prints with sharp detail, vibrant colors, and consistent results, making it suitable for a wide range of applications, including newspapers, magazines, books, packaging, and marketing materials. Offset printing offers advantages such as fast printing speeds, cost-effectiveness for large print runs, and compatibility with a variety of paper stocks and finishes. |
Opacity Opacity refers to the degree to which a material or substance blocks the transmission of light or allows objects behind it to be obscured or concealed. In the context of printing, opacity is an important property of paper, ink, and other printing materials that affects the visibility and legibility of printed text, images, and graphics. Opacity is typically expressed as a percentage, with higher opacity indicating greater light-blocking ability and less see-through or show-through of underlying layers.
Opacity is influenced by factors such as paper thickness, weight, and composition, as well as ink coverage, color density, and printing process. High-opacity papers are preferred for double-sided printing, where text and images must remain legible without interference from content printed on the reverse side. |
Open edition prints An open edition print has no limit to the number of copies made. While a limited edition print has a set number - 10, 50, or 1000, for instance, after which time no more copies will be made - open edition implies the artist can continue making prints indefinitely.
As a result, open edition prints are generally cheaper than limited editions, and will not amass the same value over time.

Overexposed In photography, exposure relates to the amount of light that was allowed to affect the image, either through the viewfinder of the camera, or in the darkroom during film development.
An overexposed image will have more light than average (generally considered too much, though some artists deliberately overexpose their images). Overexposure tends to make an image whiter, obscuring details in areas that were already well lit.
For example, if the subject is in front of a bright light, the background often must be overexposed in order for the subject's face to be visible.
|
![Overexposed](/images/glossary/overexposed.jpg) |
Overlap Similar to "offset", this refers to the amount of the artwork a picture frame lip or mat will cover on each side of the piece. An overlap is necessary to keep the contents behind from falling through the opening. |

Paper weights The weight of a piece of paper is defined by the weight in grams per square meter (gsm). Alternately, weight may be determined by what a set number of sheets would weigh in pounds. Regular bond paper that one might use in a desktop printer is generally 90 gsm or 20-24 lb.
A general breakdown of paper weights by gsm:
35-55 gsm: newspaper
130-170 gsm: posters
350 gsm: business cards |
Photoshop Digital image (raster graphics) editing software developed by Adobe. Simply defined, Photoshop allows the user to alter photographs and other digital images by applying layers of filters. Objects can be removed from the image, colors and tones can be changed, and effects can be applied to make the image look, for instance, like a watercolor painting or pencil sketch. |
Pigment A pigment is a material that changes the color of light it reflects as the result of selective color absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which the material itself emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures.
For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken. |

Platen Press Cleaner A solution used to remove left over adhesive from the surface of a platen press.
Platens are flat metal (originally wood) plates that are pressed with great force against paper to create an impression. They were originally used in letterpress printing, and today are used to cut, crease or number digital or other prints. |
PMMA PMMA or acrylic is a widely used transparent plastic material known for its applications in various markets from picture framing, car windows, smartphone screens to aquariums. It is a tough plastic, easy to shape and a great alternative to the high cost and less resilient glass. |
Polyester Resin A type of viscous polymer that is often used in casting (poured into molds). Polyester Resin differs from epoxy resin in that it has less strength, is less adhesive, and tends to shrink. For these reasons, it is not often used as a coating, as epoxy resin is. |
Post-Processing Post-processing, also known as image editing or digital darkroom techniques, refers to the process of enhancing, retouching, and refining digital photographs using software tools and techniques after they have been captured with a camera. Post-processing allows photographers to adjust various aspects of the image, including exposure, contrast, color balance, sharpness, and composition, to achieve the desired aesthetic and visual impact.
Common post-processing tasks include cropping and straightening images, adjusting exposure and white balance, enhancing colors and contrast, removing blemishes or distractions, applying creative filters and effects, and optimizing images for printing or online sharing. Popular post-processing software options include Adobe Photoshop, Adobe Lightroom, Capture One, Affinity Photo, and GIMP (GNU Image Manipulation Program), among others. Post-processing plays a crucial role in the digital photography workflow, allowing photographers to refine their vision, correct technical imperfections, and express their creativity through the manipulation and enhancement of digital images. |
Pressure-Sensitive Mounting The act of affixing an artwork to another surface (foam core, gatorboard, dibond, wood panelling, canvas, etc) with an adhesive that does not require heat or a chemical additive to adhere to the artwork's surface. The materials will stick together using the force of the hand, or a press designed to apply a great amount of pressure. |
Primary Colors A set of colors that, when combined, present as different colors. Red, green and blue are additive primary colors. When overlapped in different ratios, new colors are created. Yellow, cyan and magenta are subtractive primary colors used in mixing pigments or dyes. |

Print Size Print size refers to the dimensions of a printed image when reproduced on a physical medium, such as paper, canvas, or other printable substrates. Print size is typically measured in inches or centimeters and represents the width and height of the printed image. The print size is determined by factors such as the resolution of the digital image file, the aspect ratio of the image, and the dimensions of the physical print medium.
When printing digital images, photographers and designers often consider factors such as viewing distance, intended use, and display environment to determine the optimal print size for achieving the desired visual impact and readability. Large print sizes are suitable for wall art, gallery exhibitions, and poster displays, while smaller print sizes may be more appropriate for photo albums, greeting cards, or promotional materials. The choice of print size also affects the level of detail and clarity of the printed image, with larger prints requiring higher resolution digital files to maintain sharpness and image quality. |
Proof Sheet A small section of a digital image printed on canvas in order to determine the color saturation and texture of the inks on that particular surface. Often, multiple proofs will be printed on different surfaces with various color levels, in order to compare the results. |

Raster Image Processor (RIP) A raster image processor (RIP) is a software component or device driver used in laser engraving systems to interpret, process, and convert raster image files into engraving commands that control laser behavior. RIP software analyzes raster image data, including pixel colors, densities, and patterns, and generates engraving instructions such as laser power levels, scan speeds, and pixel mapping coordinates.
RIP software plays a critical role in optimizing engraving quality, speed, and efficiency by applying image processing algorithms, dithering techniques, and halftone patterns to raster images. Advanced RIP software may also support color management, image editing, and engraving parameter customization, allowing operators to achieve precise and accurate engraving results for a wide range of applications and materials.
Advanced RIP systems offer features such as advanced color management, screening algorithms, ink optimization, and workflow automation to optimize print quality, efficiency, and productivity. |

Satin Finish As opposed to the high shine of a glossy finish, satin finish has what is referred to as a sheen - a smoother, velvet-like softness. It is closer to a matte finish, but slightly more reflective. |
Saturation Saturation, also known as chroma or intensity, refers to the purity or vividness of a color, representing the degree to which it appears rich, vibrant, or intense. Highly saturated colors appear vivid and distinct, while desaturated colors appear duller or washed out. HSL, which stands for Hue, Saturation, and Luminance, is a color model used in digital image processing and editing to manipulate and adjust the colors within an image. Each component of the HSL color model represents a different aspect of color:
Hue: Hue refers to the pure color of an object, represented as a point on the color wheel. It defines the specific wavelength of light that is perceived by the human eye, ranging from red to orange, yellow, green, cyan, blue, and violet.
Saturation: Saturation determines the intensity or purity of a color. A fully saturated color appears vivid and vibrant, while a desaturated color contains more gray and appears dull or muted.
Luminance: Luminance refers to the brightness or lightness of a color. It represents the amount of light reflected by an object or surface, ranging from black (0% luminance) to white (100% luminance).
By adjusting the values of hue, saturation, and luminance independently, photographers and digital artists can fine-tune and manipulate the colors within an image to achieve desired visual effects, correct color casts, or enhance the overall color balance. |
Scanning Scanning is the process of converting physical documents, photographs, or images into digital format using a scanner or scanning device. During scanning, the scanner captures the optical characteristics of the original document or image and converts them into digital data, typically in the form of a raster image file (e.g., JPEG, TIFF, PNG). Scanning is commonly used for digitizing printed documents, photographs, artwork, and other visual materials for storage, distribution, manipulation, and display in electronic formats.

Sharpness Sharpness refers to the clarity and definition of details in an image, including fine textures, edges, and contours. A sharp image exhibits well-defined edges, crisp details, and high contrast between adjacent elements, resulting in a clear and visually pleasing appearance. Sharpness is influenced by various factors, including camera settings, lens quality, focus accuracy, and image processing techniques. Achieving optimal sharpness requires careful attention to these factors during image capture and post-processing.
While sharpness is often desirable in photography, it's important to recognize that the perceived level of sharpness can vary depending on factors such as viewing distance, display size, and image content. Photographers may choose to adjust sharpness settings during post-processing to enhance image clarity and visual impact, taking into account the specific characteristics and requirements of each image. |
Shellac A liquid coating derived from the excretion of a beetle found in India and Thailand. When the dried flakes are mixed with ethanol, they become a natural primer that dries solid and serves as a protective insulator, sealant or stain. Today, real shellac has been largely replaced by chemically-produced lacquer. |
Silicone Paper A type of paper that is treated with a silicone coating which prevents it from sticking to whatever it is laid against. Often used to separate artworks from one another, or placed over an artwork prior to rolling, so it does not stick to itself.

Standoff Bolts A type of metal fastener that is attached a mounted artwork (generally a plexi mount or dibond) that creates a space and shadow between the art and the wall. The bold has a flat or gently rounded, sometimes brushed silver head attached to a screw base. The screw is inserted through a hole in the corner of the artwork. Then a wide washer is placed over the screw, between the artwork back and the wall. The remainder of the protruding screw is then screwed into the wall. The result is a contemporary, frameless display style, with only the smooth heads of the bolts showing in the top two or all four corners of the artwork. |

Stretcher bar A stretcher bar is used to construct a wooden stretcher frame used by artists to mount their canvases. They are traditionally a wooden framework support on which an artist fastens a piece of canvas.
They are also used for small-scale embroidery to provide steady tension, affixing the edges of the fabric with push-pins or a staple gun before beginning to sew, and then removing it from the stretcher when the work is complete. Stretchers are usually in the shape of a rectangle, although shaped canvases are also possible.
Since a stretcher is simply a frame, it can be constructed in a variety of ways. The differences in construction have to do with how the corners are built. Commercially available, pre-fabricated stretchers come in segments with interlocking corners that can be fit together like puzzle pieces.

Stretcher frames A wooden frame made from lengths of wood (stretcher bars), around which a canvas painting or print is tightly stretched and stapled or nailed in place.
Lengths of wood are cut at a 45 degree angle with a miter saw or chopper, and joined with V nails using an underpinner machine. If the frame is large, extra cross beams may be inserted for added support.
Stretcher bars come in a wide range of depths, depending on the artist or customer's preference. The most common stretcher frame depths are 1 1 1/2" and 3/4". The depth translates to how far out from the wall the face of the canvas will protrude when hung. When a stretched canvas is being framed in a regular picture frame, the framer may use a very shallow stretcher bar of 1/2" or 7/16".

Stretcher Key Small wedges of wood that can be inserted into the corners of a stretcher bar frame to make it a little bit larger. This is done because canvases can stretch out over time, and begin to sag on the frame.
Stretcher keys work only for half lap-jointed stretcher bars, because there is a gap within the wood. If the frame was constructed by a framer and attached with mitered corners, this method will not work. |
Sublimation Sublimation is a process where an image can be printed onto transfer paper using dye-based inks and then with heat and pressure become transferred into the substrate.
Dye sublimation on hard surface surfaces is possible if the surfaces have been coated. Instead of printing images directly on a surface, which may scratch easily, the image is infused into the coating to provide permanent protection and durability.
|
Substrate In printing and imaging, a substrate refers to the underlying material or surface onto which images, text, or graphics are printed or transferred. Common substrates include paper, cardboard, canvas, fabric, plastic, metal, glass, and wood. The choice of substrate depends on factors such as the printing process, intended use, durability requirements, and desired aesthetic qualities. Substrates vary in characteristics such as texture, weight, opacity, absorbency, smoothness, and finish, influencing the visual appearance, tactile feel, and longevity of printed materials. |

Tint A tint is a color created when a solid color is mixed with white, creating a lighter version of the color. In contrast, a "shade" is a color mixed with black to create a darker version of the color. In printing and color reproduction, a tint refers to a variation of a base color achieved by adding white or another lightening agent to lighten or dilute the color's intensity. Tints are commonly used to create subtle variations in color, achieve pastel shades, or adjust the brightness and saturation of colors in printed materials. Tints play a vital role in color matching, color correction, and color harmony in graphic design, illustration, and printing. |

Tone Tone refers to the degree of lightness or darkness of a color, often described in terms of its brightness or value. In visual arts, tone is an essential aspect of color theory and perception, influencing the overall mood, contrast, and visual impact of an image or artwork. Tones range from light to dark along a grayscale or tonal scale, with lighter tones containing more white or lightness and darker tones containing more black or darkness. Adjusting tone can alter the perceived depth, form, and spatial relationships within an image, affecting its composition and emotional resonance. |

United Inch United inches is a term used in the framing industry to describe the size of a print for the purpose of pricing. The number of united inches in any given image is the sum of its length and its width (one side only for each). Thus, in effect, it represents 1/2 the perimeter of the print. For example, an image that is 10 x 20 has 30 united inches, and a 24 x 36 inch print has 60 united inches. |
Unprimed Canvas An artist's canvas that has not been treated with a clear or white primer. As a result, when the paint is applied, it is readily absorbed into the fibers of the canvas, affecting the appearance. Though whether or not to use unprimed canvas is the choice of the artist, in the case of oil painting unprimed canvas can be problematic, since the oil paints will cause the raw canvas to rot. In addition to creating a smoother surface for the paint, primer protects the canvas from the elements.

Watercolor painting Watercolor painting is a painting method. A watercolor is the medium or the resulting artwork, in which the paints are made of pigments suspended in a water soluble vehicle. The traditional and most common support for watercolor paintings is paper; other supports include papyrus, bark papers, plastics, vellum or leather, fabric, wood, and canvas. In East Asia, watercolor painting with inks is referred to as brush painting or scroll painting. In Chinese and Japanese painting it has been the dominant medium, often in monochrome black or browns. India, Ethiopia and other countries also have long traditions. Finger painting with watercolor paints originated in China. |

Watercolor Paper Watercolor paper is a specialized type of paper designed specifically for use with watercolor paints and techniques. Watercolor paper is characterized by its thickness, absorbency, texture, and durability, which allow it to withstand the application of wet media without buckling, warping, or deteriorating.
Watercolor paper is typically made from high-quality cotton or cellulose fibers and is available in various weights, surface textures (such as rough, cold-pressed, and hot-pressed), and formats (such as sheets, pads, and blocks). The choice of watercolor paper depends on factors such as painting style, technique, desired effects, and personal preference. Rough-textured papers are favored for expressive brushwork and organic effects, while smooth papers are preferred for detailed work and controlled washes. |
Wet Mounting The process of adhering a print to a rigid backing such as foam core, gatorboard or wood using a wet adhesive (glue, paste) that adheres as it dries. In contrast, dry mounting uses a "dry" adhesive that is activated by heat rather than air dryinh. |
White Point White point, also known as chromatic white or reference white, refers to the color temperature or chromaticity coordinates that define the neutral white appearance of a display device or imaging system under standard viewing conditions. The white point represents the color of pure white light perceived by the human eye and serves as a reference for calibrating and reproducing accurate colors across different devices and media.
Common white point standards include D65 (daylight with a correlated color temperature of 6500 Kelvin) for graphic arts and photography, and D50 (daylight with a correlated color temperature of 5000 Kelvin) for color matching and proofing applications. White point calibration ensures consistency and color accuracy in digital imaging, printing, and display technologies, preventing color shifts, tinting, and inaccuracies in color reproduction. |

Yellow CMYK is a color model used in color printing and reproduction processes. It stands for Cyan, Magenta, Yellow, and Black, representing the four primary colors used in subtractive color mixing. In CMYK printing, each color is represented by a separate ink or toner, and varying combinations of these four colors can produce a wide range of colors and tones.
Cyan, magenta, and yellow are subtractive primary colors, meaning they subtract or absorb specific wavelengths of light, while black (K) is added to improve color depth and contrast. CMYK is commonly used in commercial printing processes, such as magazines, newspapers, and packaging, where precise color reproduction and consistency are essential. |
Yellowing A process that results in discoloration of a mat board, backing, Resin Coating or artwork paper. Yellowing is caused by exposure to light, or chemical reactions that cause the substances added to whiten the paper to break down over time.
Though sometimes a desired look, yellowing is generally detrimental to artwork, and affects its longevity. |
