ABSTRACT:
A software based proofing method allowing to proof and measure registration between both sides of a press sheet by displaying, on a color monitor, both sides superimposed on each other. By making the paper appear transparent the front-to-back registration can be accurately measured and corrected. The data to be displayed is taken from a low resolution raster processor identical in operation to a full resolution raster processor used to generate the output data for the film or plate imaging device. For color files the color separation files are used instead of the composite file in order to be able to proof color registration and trapping between any colors. By using the same files as the imaging device the highest accuracy is achieved.
