I tried psprints and they were unable to deliver a reliable and color correct product. Overnightprints doesn't have any options for posters other than 11x17".

I'm looking for a digital printing service that can produce quality product. Preferably one that uses rgb so I don't have to sweat color profile problems. A variety of paper weights and sizes for posters would be fantastic.

Of course I'm on a short deadline. Psprints really put me in a hurt bag.
