CMYK color model
The CMYK color model is the standard model which is used in color printing both professionally and at home. By combining inks in this color model a broad range of colors can be produced.
CMYK stands for Cyan Magenta Yellow and Black. The K used in the acronym stands for the German word “Kohle” meaning Coal.
Since four basic colors are used in this color model it’s often called four-color printing. For more information on the subject, please go to our CMY color model article that explains the CMY, RGB and RBY color models in more depth.
