Abstract:
1. Apparatus for simulating the effects of printing process-relevant setting commands on an image to be printed on a printing press, said apparatus comprising: a color management unit for transforming printing-specific image data of an image to be printed into screen-specific display data defined in an RGB target color space, wherein said image data have been defined in a CMYK source color space comprising the scale colors cyan, magenta, yellow, and black as participants in halftone combination printing; at least one true color monitor for displaying the image to be printed in a true color manner on the basis of the screen-specific display data defined in the RGB target color space, said at least one monitor being connected to the color management unit; an input unit for entering the printing process-relevant setting commands for changing the image in isolation from the printing press, wherein the printing-process-relevant setting commands are commands for controlling the printing process on the printing press and are at least one of a final density and surface coverage; and a manipulation unit, which simulates the effects of the entered setting commands by automatically adjusting the display data defined in the RGB target color space on the basis of the entered setting commands so that the image displayed on the true color monitor simulates, in a true color manner isolated from the printing process, image changes made by the entered setting commands, whereby an updated color reference for the print image reflecting at least one of changes and optimizations achieved by the setting commands is obtained, wherein the printing process setting commands are at least one of final density and coverage, and wherein the setting commands cause a change in at least one of the final density values and the surface coverage values, whereby the manipulation unit is configured to adjust the display data of the RGB target color space automatically such that at least one of full-tone values and tone value ranges are changed in the RGB color space, the adjustments depending on the printing conditions.
