| titleOfInvention | Electrophotographic color proofing system for gravure printed images |
| abstract | A color proofing system (10) effectively produces off-press proofs for gravure printed images using a high resolution electrophotographic printer by optimizing the deposition profile of a clustered dot cell of electrophotographically developed ink dots so as to more closely simulate the deposition profile of ink deposited in conventional and direct transfer (halftone) gravure printing processes. The three operating parameters of the electrophotographic process that are selectively modified during this process to produce are: (1) the spot image overlap of the laser beam profile; (2) the charge differentiation between the non-charged and charged areas on the photoconductor; and (3) the charge density associated with the toner particles deposited on the photoconductor surface. The gravure dot cells produced by this process can vary in both cell area and ink thickness. The resulting variation in ink thickness, graduated edge profile, and overlapping of adjacent gravure dot cells allows the ink deposited on top of a paper substrate by the electrophotographic process to more closely simulate the color and tone reproduction of ink that is absorbed into the paper in a gravure press printing. Thus, the tonal rendition of the finished off-press proof more accurately simulates gravure printing than any previously known gravure proofing process. |
