Information on this site is targeted at photographers who are involved in the print production and who want to have control over color till the final contract proof. This means the usage of a professional proof software and the possibility for the verifications of proofs according to PSO or SWOP / GRACoL. It is also necessary to have some basic knowledge about the CMYK settings in Photoshop and how they influence the separation and printability in offset printing.
