Explanation

The term CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It is a subtractive color model used primarily in the printing industry, including offset printing. In this process, these four ink colors are layered in varying proportions to create a full spectrum of colors on paper. While digital screens use the RGB (Red, Green, Blue) model, physical printing relies on the CMYK model to produce accurate color reproductions for books, newspapers, and magazines. Therefore, it is directly related to offset printing.
