About Hard Copy Proofs
UPrinting offers hard copy proofs for clients with color critical art. These color proofs are printed on our highly calibrated EPSON proofing system and are closest representation of the final printed pieces.
Hard Copy proofs are printed using Kodak Proofing Stock, which is different from the actual paper we will use when printing your order. While its main purpose is to show color, variations may occur depending on the finish selected (AQ, Matte, UV) for the final print job. We do not offer hard copy proofs for art that will be printed on uncoated paper.
