Patent ID: 8681376

Claim:
A method for the production of test prints of print data intended for printing on an industrial printing machine on a digital printer, wherein the print data are converted from a color space for an industrial printing machine into digital proof print data in a color space for a digital printer, as a function of a given state, with conversion tables, wherein the given state comprises parameters selected from the group consisting of paper type, ink, printing mode, and any combinations thereof, wherein calibration data are determined during the printing process for a calibration file for the printer based on data compatible with the color space, by printing a test image, measuring the test image, and comparing the test image to a printer target image, wherein parameters dependent on a measuring device used during the measuring of the test image are considered during the determination of the calibration data, wherein the calibration data are subjected to a validity check, with a period for carrying out the validity check that is predetermined, wherein a period of validity is determined for the calibration data, after which the calibration data automatically become invalid, and wherein a quality logo is printed out on the test print.
