Method and device for creating a colour reference for a printed image

摘要

The method involves generating lower-resolution image data from high-resolution raster data for an image. The lower-resolution data are converted into display data which serve as color reference for the image to be printed and is visualized on a true-color monitor. An actual transmission characteristic ascertained is compared with a specified transmission characteristic. A correction curve is calculated to arrive at the desired transmission characteristic starting with the actual transmission characteristic. The display data are ascertained using the calculated correction curve. An independent claim is also included for an apparatus for generating a color reference for an image to be printed for visualizing the reference on a true-color monitor.
