Abstract: Two-dimensional material sheets are stacked in a stacking device. One of a printing machine and a coating machine has at least one stacking unit having a stacking space. Material sheets are conveyed, via the stacking space of the stacking unit, comprised by the stacking device, and are deposited into a stack on top of one another on a loading aid. For two different production runs, the stacks are formed on the loading aid with the four corners of their areas in mutually different relative orientations with respect to the loading aid, which is arranged, in each case, in the stacking space of the stacking unit and is larger-format compared with the material sheets to be deposited in each case. For the two production runs, in each case, one loading aid of the same format is positioned on different positions, as seen in projection in the horizontal, in the stacking space of the stacking unit.

Abstract: A method for operating a device for printing hollow cylinder is provided. The device comprises a rotating segmented wheel with a plurality of printing cylinders arranged successively along the periphery of the device. A plurality of plate cylinders are provided in association with the segmented wheel. According to a printing process to be performed, a selected quantity of plate cylinders is thrown onto the segment wheel or is thrown off the segment wheel. In a first printing process, a first partial quantity of thrown-on plate cylinders transfers printing ink to a plurality of the printing blankets arranged on the segment wheel. At the end of the printing process, at least some of the plate cylinders, that were thrown on the segment wheel in the first printing process, are thrown off the rotating segment wheel.

Abstract: A method is provided for printing on hollow bodies in which the hollow bodies are printed on in a decorator having a rotating segment wheel. Printing ink provided by multiple different plate cylinders and inking units are each collected on printing blankets arranged one after another on the circumference of the segment wheel. The plate cylinders and inking units involved in the printing are arranged and set in such a way that, when printing on the hollow body, an iris print is, or at least can be implemented.
