Rich Black. ich Black is used to refer to a mixture containing the four process colors: cyan, magenta, yellow, and black (CMYK) colors. This is necessary because no black ink is truly black, and the combination of the four inks will result in a denser black, or ârich black.â The printing industry has many definitions of rich black.
For example, skin tones, the color of the sky and foliage are all such colors that we notice if they are even slightly off. Based on these limitations, weâve found that CMYK is most appropriate for printing images that are: 1  Cartoony or fantastic graphics. 2  Washed out or distressed full color graphics. 3  Full Color on a budget where accurate reproduction isnât as important.
