We work here in full RGB color scheme while most of the printing goes in CMYK which offers narrower palette due to chemistry of the printing process itself.

However, they "on screen" impact is limited.
Print shop has the last word and I can only add that we can also provide here
black and white version if requested and it can be useful with some kinds of documents like fax.
