HD Pixel Print has provided you with this guide detailing the differences between RGB and CMYK colour gamuts. It also explains why CMYK should be used for commercially printed documents and also helps to show you how to check colour settings in various popular software packages.
Please note: when ordering, we do not automatically check, set up and convert all colours to CMYK because sometimes this can cause noticeable colour variation.
