Involves the reduction of dot percentages of cyan, magenta, and yellow inks in dark neutral areas and replacing the lost density by means of a heavier black plate.
In CMYK color calculation, the removal of some or all of the cyan, magenta, and yellow inks where black ink is to be substituted See also: black generation
Reducing the amount of cyan, magenta and yellow ink in the midtones and shadow areas of an image, whilst the amount of black ink is increased. Commonly referred to as UCR.
The removing of cyan, magenta, or yellow from a heavily colored image to limit the total amount of ink being applied to that image to avoid potential production problems.
A technique for adding detail by replacing equal percentages of cyan, magenta, and yellow inks in the printing process with black ink. This is similar to Gray Component Replacement (GCR), but is applied only to neutral areas of the printed image. This can be accomplished manually by making changes to color separation films or digitally by editing software. See also IMAGE CMYK COLOR SEPARATION EDITING SUBTRACTIVE PRIMARY COLORS
The process of converting quantities of cyan, magenta, and yellow in black or neutral shadow areas of an image to equivalent gray levels which are then printed using black ink. UCR uses less ink and can eliminate trapping problems in dark areas without altering color saturation of hue.
Technique of making color separations such that the amount of cyan, magenta and yellow ink is reduced in midtone and shadow areas while the amount of black is increased. Abbreviated UCR.
To improve trapping and reduce ink costs in the process color web printing, color separation films are reduced in color in areas where all three colors overprint and the black film is increased an equivalent amount in these areas.
