Printing custom covers - service?

[rybev]

I've had a play around but still very poor reproduction.
I'm using Kodak glossy picture paper which according to the packaging is the 3rd best..... there is Kodak Ultima Picture Paper for long-lasting professional quality.

Should i invest in that?

I wish i could explain how my printing looks, it's sort of like it's been done on a colour photo-copier thats about 10 years old. Some colours good but the blacks are washed out and the small pictures that are on the back of the cover look a bit like they're out of a colour newspaper
