CMYK is the most common digital print method. It is a colour mode made up of Cyan, Magenta, Yellow and Black (CYMK). It’s an effective print process that creates high quality finished results, however we may not be able to print in some bright colours. RGB is a colour mode made up of Red, Green and Blue (RGB) light. It is used in screens (those used on your computer, TV etc.) producing bright and vibrant colours. RGB is for displays and isn’t used for printing, so we use the closest CMYK equivalent.
