Abstract:
The disclosure relates to a method for printing a paper web with at least one print motif by means of a digital printing facility. The method includes: providing a digital image of a master sample of the print motif, printing a plurality of copies of a section of the at least one print motif with different color settings, creating digital images of the printed copies, comparing the digital images of the printed copies with the digital image of the master sample, where a degree of similarity is determined in each case, selecting color settings using the determined degrees of similarity and printing the print motif onto the paper web with the selected color settings.
