Patent ID: 7375857

Claim:
A proof generation method for proof printers, comprising the steps of: receiving halftoned primary color print data to be printed on a target halftone printing press, wherein the halftoned primary color print data has been produced by a first halftoning technique, and wherein the first halftoning technique is at least comparable to a target halftoning technique used by the target halftone printing press, applying a second halftoning technique to the print data, wherein the first and second halftoning techniques are different, and providing the data to a proofing printer different from the target halftone printing press, wherein the first and second halftoning techniques are selected to: (a) cause a dot size in the data provided to the proofing printer to substantially match a dot size for the halftone printing press; and (b) cause a proof produced by the proofing printer to substantially match the color of a print produced by the target halftone printing press.
