discusses the difference between RGB and CMYK

One of the issues we have with supplied artwork for printing is that it is supplied in RGB. What's the problem with that I hear you say?

Well let me explain....

Firstly, the difference between the two, in short is:


RGB is the colour scheme that is often associated with electronic display screens such as cameras, TV’s and computer monitors (like the one you are currently looking at). RGB stands for three colours:

R = Red
G = Green
B = Blue

These three colours are mixed together on a screen to create every other colour you see. RGB is an additive colour model. This means that the 3 main colours are mixed together to create the various range of colours that you can see on electronic platforms.


CMYK is the colour scheme that is used by printers to create the many colours that end up on your printed page. It is made up of four colours:

C = Cyan
M = Magenta
Y = Yellow
K = Black

This is often why your printed material looks different to the pdf you received at proof stage. So, when designing your material for print remember to convert to CMYK from the original RGB, which is possible to do by using software such as Adobe Photoshop Illustrator.
