I don't understand, I have never had a problem getting high quality prints using factory inks and paper. I've tried non-factory papers for glossy photos and have ended up giving the paper away. Kodak paper on my printer gives a very warm tone, but I use the double sided paper but it's not for photographs is the colors are not a problem.

I've found the if you use coated or uncoated mat papers there is almost never a color problem.

I always have printed my digital prints at home, and cost wise it's about the same but I get my prints in a few minutes with out driving anyplace.
