Firstly let’s get the CMYK acronym out into the open – it stands for Cyan, Magenta, Yellow and Black. Yes, I know ‘black’ is with a ‘B’ so why not CMYB? Well, ‘B’ is already used for ‘Blue’ in RGB, so it would be confusing. The ‘K’ apparently stands for Key (or perhaps its just the last letter of black… who knows). CMYK is the standard in the printing industry, and pretty much most of what you see these days, by way of printed media, is CMYK. Anyone who’s ever owned a colour inkjet printer is sure to recall buying ink cartridges in those four colours, with which you could print almost anything – even full-colour photographs.
