Artwork files for commercial printing should be set up using the CMYK (Cyan, Magenta, Yellow, Key/Black) colour mode for several reasons. Firstly, CMYK is the industry standard for printing and is supported by most printers. Secondly, CMYK allows for accurate colour representation on printed materials, ensuring that the colours in your design match what you see on your screen. Thirdly, CMYK is a subtractive colour model, meaning it absorbs and subtracts light to produce colour, making it more suitable for printing as it allows for more control over the final printed colours. In contrast, the RGB (Red, Green, Blue) colour mode is an additive colour model that produces colour by adding light and is better suited for electronic displays such as computer monitors and televisions. Using CMYK ensures that your artwork files are optimized for printing and that the final printed product meets your expectations.

Intertype Publishing and Printing uses state-of-the-art digital printing technology. The platforms are all capable of printing RGB colour values however colour accuracy and repeatability will be seriously compromised. Stick with CMYK for the best results.
