The CMYK acronym stands for Cyan, Magenta, Yellow, and Key: those are the colours used in the printing process. A printing press uses dots of ink to make up the image from these four colours. ‘Key’ actually means black. … For example, cyan and yellow create a green when one is overlaid on the other.
What is the difference between RGB and CMYK color mode?
RGB refers to the primary colors of light, Red, Green and Blue, that are used in monitors, television screens, digital cameras and scanners.

What CMYK profile is best for printing?
When designing for a printed format, the best color profile to use is CMYK, which uses the base colors of Cyan, Magenta, Yellow, and Key (or Black). These colors are usually expressed as percentages of each base color, for example a deep plum color would be expressed like this: C=74 M=89 Y=27 K=13.
