What is CMYK?

CMYK is an acronym for an image in which the apparent colors are produced by combining image elements in Cyan, Magenta, Yellow, and BlacK inks or dyes. These 4 colors are primary “subtractive” colors. So, by combining these colorants in varying quantities, a large number of familiar colors can be created. These primary colors are sometimes also called “process” colors because a well-understood sequence of processes can be used to combine these basic colorants into a wide range of colored effects.
