Process colours (CMYK)

In traditional four-colour printing, colours are produced by mixing cyan, magenta, yellow and black. We recommend: The print files you supply should be created purely in CMYK. Colour variations may occur when using full-tone colours (including with alternative CMYK colour spaces), NChannel, DeviceN colour spaces, Lab or RGB colour spaces.

Full-tone colours (e.g. HKS, PANTONE) 

A spot colour (also known as a special colour), is a premixed ink. The advantage of a full-tone colour is that it allows colours that cannot be created purely by the four-colour process to be printed. Two well-known producers of full-tone inks are HKS and PANTONE. Some of our products can be printed with a HKS colour (e.g. letterheaded paper 2/0 2/1 colours).
