Abstract
A method and apparatus for isochromatic simulation of a multi-colored reproduction on a color monitor. Before simulation, colors are generated on the color monitor and are matched to corner colors of a printed color chart or the like by measuring or visual comparison. The color values required for the chromatically coinciding generation of the corner colors on the color monitor are measured and allocated to color separation values of the corner colors. The color values required for generating intermediate colors are calculated upon consideration of the printing process of the multi-colored reproduction and are allocated to the corresponding color separation values of the intermediate colors. During the simulation, the color separation values of the multi-colored reproduction are output, modified according to a gradation curve, and transformed into the color values for driving the color monitor in accordance with the previously identified allocations.
