The disclosure relates to a method for detecting deviations of extension of decorations on printed decorative papers, the method includes the following steps: providing the printed decorative paper on a sample table, projecting a target pattern onto the sample table and the printed decorative paper such that a distance between two predetermined pattern elements of the projected target pattern corresponds to a target distance between at least two predetermined decorative elements of the decoration, determining deviations between the actual distance of the decorative elements and the distance between the projected pattern elements.

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.

The disclosure relates to a method for processing an object, in which a printed image is printed onto the object by a digital printing facility and the object is then further processed in at least one work station. The at least one work station being controlled by an electric control unit, where at least one control character is applied to the object by the digital printing facility, the control character being detected in or upstream of the work station by at least one sensor and transmitted to the electric control unit, which controls the at least one work station depending on the control character transmitted.

The invention relates to a method for producing decorative paper, in which a decorative design in printed onto a paper web. According to the method, a digital printing system is used, the paper web has a grammage of at least 45 g/m 2 and at most 65 g/m 2 , a primer is applied to the paper web in a application amount of at least 4 g/m 2 and at most 6 g/m 2 , preferably 5 g/m 2 , prior to the decorative design being printed on, and the decorative design is printed on with at most 7.5 g/m 2 printing ink.

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.

The disclosure relates to a method for producing a decorative paper by a digital printing machine, wherein the method comprises the following steps: a. providing at least one base stock; b. printing a surface of the base stock with a primer, so as to result in a printed base stock; c. printing the surface of the printed base stock with at least one printing ink by means of the digital printing machine, wherein, at at least one location, the surface of the base stock is not printed with the primer or with the printing ink.
