Color profiles for printing bear the suffix ICC. There is an ICC 
mailing list.  There is a web site also.  Europeans seem to be more 
into profiles than Americans.  "Scribus, the Official Manual" has 
many references to ICC profiles. But I would start with the web 
site first.  Google under "ICC Profile". 

I don't know of a way to incorporate an ICC profile in a TeX 
document short of using Distiller or even Scribus.
