Colours must be set to CMYK (Cyan, Magenta, Yellow and Black) this is because these are the colours used in the printing process.

The colours used to display your artwork on screen are made up of Red, Green and Blue (RGB) and it is not always possible to match the RGB colour range with CMYK.

If you supply us RGB artwork we will convert it to CMYK but the colours may not be as you might expect!
