What is the difference between the RGB and CMYK colour space, why does it matter?
RGB refers to the primary colours of light, Red, Green and Blue that are used in monitors, television screens, digital cameras and scanners. CMYK refers to the primary colours of pigment: Cyan, Magenta, Yellow, and Black. These are the inks used on the press in “4-color process printing”, commonly referred to as “full colour printing”. The combination of RGB light creates white, while the combination of CMYK inks creates black. Therefore, it is physically impossible for the printing press to exactly reproduce colours as we see them on our monitors. Many programs have the capability to convert the layout/images from the RGB colour space to the CMYK colour space. We request that you convert your colours from RGB to CMYK if your tools allow you to. By doing it yourself, you have maximum control over the results. You may notice a shift in colour when converting from RGB to CMYK.
