CMYK definition

CMYK stands for cyan, magenta, yellow and key (black).  It is a color system that is used by printers to put each color on a separate printing plate in order to create a final full color image.  It is also known as “four color printing.”  It should be noted that the majority of giclee printers print to an inkjet printer in RGB.  This is because there exists a superior color gamut, and images are captured in RGB by scanners.
