What is litho / offset printing?

Litho printing creates the finished image from 4 separate colours: Cyan, Magenta, Yellow and Black (CMYK)*. Printing plates are made from electronic files, which then transfer the ink onto the surface one colour at a time.

This method allows a wider graduation in colour and tones, and as a result photographic images come out exceptionally well.
