What is CMYK?

CMYK stands for Cyan, Magenta, Yellow and Key (black) and is a colour model used in printing. Printers combine these four colours in different proportions to produce a wide range of colours. In contrast to RGB, which is used in the digital space, CMYK is used for printed materials such as business cards, brochures and posters.

Correctly converting RGB (the colour model used on screens) to CMYK is an important step in ensuring that colours look the same in print as they do on screen. If this step is not carried out carefully, it can lead to colour deviations.
