Gray Component Replacement. A technique for adding detail to an image by reducing the amounts of cyan, magenta, and yellow and replacing them with black.
Grey component replacement. A color separation setting used on color photographs where cyan, magenta and yellow inks are swapped out of an image (in a balance that would yield a grey value) and black ink is swapped in instead. The advantages are a reduction in overall ink usage, a more consistent press run, and some increase in image detail.
gray component replacement. Also called achromatic color replacement (ACR), integrated color removal (ICR), and polychromatic color removal (PCR). Removing the achromatic (also called contaminant or graying) component of cyan, magenta, and yellow when they all combine and replacing it with black. Gray component replacement is distinct from under color removal, which reduces process colors in only dark, neutral areas and adds black. GCR separation is done with specialized software on electronic scanners.
Gray component reduction. A method of producing a COLOR SEPARATION that represents dark tones and gray values in an image by combining all four of the primary colors Cyan, Magenta, Yellow, and Black. GCR produces images with richer color and higher saturation than UCR, at the cost of greater TOTAL INK. GCR is usually used to produce CMYK images that will be printed on glossy paper.
Black ink replacement of neutral colours throughout an image in a colour separation (CMYK image)
The process by which gray tones are proportionally removed from the exact amounts of cyan, magenta and yellow that make up gray and replaced by the corresponding quantity of black ink. This is primarily performed for neutral color tones and in the gray components of unsaturated colors. The process allows for ink reduction and reduces the effects of color shifts.
Grey Component Replacement. Commonly known as GCR, this process involves replacing the grey tone in the cyan, magenta and yellow plates, with black ink, during the colour separation process. Not to be confused with Undercolor Removal.
Acronym for Grey Component Replacement.
Gray component replacement, a separation technique for replacing cyan, magenta, and yellow inks with black.
Gray component replacement. A color separation term referring to the act of removing a percentage of cyan, magenta and yellow inks from an image and replacing them with black ink. This reduces the total amount of ink in the images, allowing better print quality.
Gray component replacement. A technique for adding detail by reducing the amount of cyan, magenta and yellow in chromatic or coloured areas, replacing them with black.
Gray component replacement. A color separation technique that uses black instead of combinations of cyan, magenta, and yellow in reproducing the gray components of colors. This provides a more economical use of inks and improved color trapping.
Abbreviation for gray component replacement, a technique for minimizing ink coverage. When TrapWise converts RGB data to CMYK, it analyzes a bitmap image for gray tones composed of cyan, magenta, or yellow and replaces those colors with a similar percentage of black.
Acronym for Gray Component Replacement.
Gray Component Replacement. The technique of replacing gray tones in the yellow, cyan and magenta films, made while color separating, with black ink. Also referred to as achromatic color removal.
Color separation process in which black ink is used to replace cyan, magenta, and yellow (CMY) in mid-tome and highlight areas where the three inks overlap, in order to reduce ink consumption and drying time. (Similar to UCR.)
A type of process colour separation that determines the amount of black ink used to replace Cyan, Magenta, and Yellow in areas where those three inks overlap.
Abbreviation for gray component replacement; the separation technique where black ink is used to replace either a portion of the unwanted component in a saturated colour, or a combination of cyan, magenta, and yellow equivalent to the unwanted component. Typically specified to improve colour control on older presses.
Scanners. A technique for reducing the amount of cyan, magenta and yellow in an area and replacing them with an appropriate level of black
