Abstract:
1. A method for generating a color reference for an image to be printed for visualizing the reference on a true-color monitor, where lower-resolution image data are generated from high-resolution raster data for the image to be printed which are obtained with aid of a raster image processor from page description data for the image to be printed, wherein the lower-resolution image data are converted with aid of a color management device into display data which serve as color reference for the image to be printed and which are visualizable on the true-color monitor, the method comprising the steps of: a) an actual transmission characteristic is ascertained which is used in the raster image processor to generate corresponding raster data from the page description data for the image to be printed; b) the actual transmission characteristic ascertained is compared with a specified reference transmission characteristic, where, on a basis of this comparison, a correction curve is calculated which is required to arrive at a reference transmission characteristic starting from the actual transmission characteristic; and c) the display data are ascertained using the calculated correction curve.
