Abstract: The disclosure relates to a method for printing a decorative pattern onto a surface of a paper that includes: applying a primer to a surface of an unprinted base paper, printing a grid marking and a decorative pattern onto a primer-coated base paper, thereby obtaining a printed base paper, detecting a grid spacing between at least two points of the grid marking to determine an actual state of the printed base paper, comparing the detected grid spacing according to the actual state with a grid spacing digitally stored as a target state for the printed decorative pattern, amending the stored target grid spacing based on the comparison by creating an amended target grid spacing and a decorative pattern amended therewith and/or amending at least one process parameter for controlling the application of the primer and/or the printing of the grid marking and/or the drying until a predetermined criterion is met.

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.

Abstract: The disclosure relates to a method for producing a circumferential packaging for a paper roll. The paper roll has a wound paper web and two opposing end faces and a circumferential surface that connected the end faces to each other. The method includes the following steps: applying a protective material in liquid form to an end section of the paper web by at least one application unit, the protective material being applied to one of two sides of the end section of the paper web, winding up the end section of the paper web, so that the end section forms at least one outer layer of the paper roll, and curing the protective material, resulting in a protective layer that covers the circumferential surface.
