Abstract
An apparatus and a method for exchanging information about tonal values and calorimetric values between a prepress stage, a printing stage and a quality control stage are provided. The apparatus and the method create characteristic curves which are used to optimize a process calibration and a color calibration.
Claims17
In a printing system including a prepress stage, a printing stage, a quality control stage and data links for exchanging image generation information and color measuring data between the prepress stage, the printing stage and the quality control stage, an apparatus for creating at least one of color-calibration characteristic curves and process-calibration characteristic curves, comprising:
- a computing device provided in the prepress stage;
- and
- said computing device being configured to at least one of determine and transfer image generation information serving as a test pattern for generating at least one of color-calibration characteristic data and process-calibration characteristic data.
A method of creating at least one of color-calibration characteristic curves and process-calibration characteristic curves, the method which comprises:
- providing data links for exchanging image and color data between a prepress stage, a printing stage and a quality control stage;
- creating image generation information in the prepress stage, the image generation information serving as a test pattern;
- and
- assigning the image generation information to a standardized data packet and supplying the image generation information to the quality control stage.
