What colours should I use? RGB or CMYK?
Our recommendation: Use CMYK for the best representation of the final result.
If you decide to use RGB, we will convert it to CMYK. This conversion process can sometimes lead to undesired colour differences. Do not hesitate to submit your RGB files to us. We will make sure they are properly converted to CMYK. We have to use CMYK simply because RGB is not suitable for printing.
