Patent ID: 7400335

Claim:
A method for printing a halftone digital image on both a printing press and a color proofer using the same binary digital data comprising: generating binary digital data that defines a halftone image, the binary digital data representing presence or absence of micropixels in the forming of halftone dots; making a printing plate from said binary digital data; making a press sheet using said printing press with said; printing plate: operating upon said binary digital data by a dot-gain processor for conditioning said binary digital data to provide a predetermined level of dot-gain, the dot-gain providing binary digital data corresponding to increasing sizes of halftone dots by adding respective micropixels thereto; providing said conditioned binary digital data to said color proofer; printing a halftone color proof on said color proofer; and wherein a raster image processor provides dot-gain in generating of said conditioned binary digital data, the dot-gain provided by said raster image processor being conditioned for use by the color proofer; and operating on said conditioned binary digital data to unbuild the dot-gain provided by said raster image processor and build in dot-gain correction to form binary digital data that is conditioned for use in forming of a printed sheet by said printing press.
