CMYK is a subtractive color model that is used in color printing, and it refers to cyan, magenta, yellow, and black for the inks used in color printing. The âKâ in CMYK is understood to be the key since in four-color printing cyan, magenta, and yellow printing plates are aligned with the black plate which is the key. In other words the other colors are setup in relation to the black which is thus the key to the process. The fact that it is subtractive means that in the CMYK process the color results are achieved by masking colors on a lighter background.

These are the inks used on the press in 4-color process printing, commonly referred to as full color printing or four color printing. The combination of RGB light creates white, while the combination of CMYK inks creates black.bout RGB-CMYK. 1  Scanners, digital cameras and computer monitors use red, green and blue (RGB) light to display color. 2  Commercial printing presses print with cyan, magenta, yellow and black (CMYK) ink, called process printing, instead of RGB light, and therefore produce a different range of color.
