s parameters to perform color transformations.
Gamut mapping
A gamut is the range of colors that a device can produce. Gamut mapping refers to the redefining of a device's colors so that its gamut becomes more or less identical to that of another device. If, for example, you scan an image of a rain forest with more shades of green than your printer can reproduce, gamut mapping substitutes colors so that the overall impression on the human eye comes close to that of the original.
ICC
Stands for the International Color Co
nsortium, a group of vendors who defined the ICC profile format, a cross-platform specification that allows developers to create profile tools and applications supporting the ICC profile standard. Founding ICC members include Adobe, Agfa, Apple, Kodak, Microsoft, Silicon Graphics, Sun, and Taligent.
ICM
Stands for Image Color Matching, Microsoft's color-matching standard for Windows 95. It's based on the Kodak Precision Color Management System (KPCMS).
LAB colors
In LAB colors, the L-value stands for brightness (on a scale of 0 to 100), and the A and B coordinates define the distance of a color from a reference white point. The LAB color space includes all visible colors and is device independent.
OPI
Stands for Open Prepress Interface. Facilitates the handling of print jobs with large amounts of image data. Original high-resolution images are kept on an OPI server. Layout applications can then work with small low-resolution substitute
s, so the processing of material goes much faster.
Profile
A device description that contains information about how a given device -- such as a scanner, monitor, or printer -- mixes and reproduces colors.
