Method and device for the markless control or regulation of a digital printing process
A method for checking intermediate, part or end products during the production process without using marks is disclosed. The print image of the intermediate, part or end product produced on a digital printing press is scanned at least after a predetermined production step in order to subsequently compare the scanned print image with stored product data. Based on the comparison, the check of the previous processing steps and/or the calculation of the subsequent control actions for the order allocated to the intermediate, part or end product and the control actions by the production device are carried out.
A folding roller for use in a folding device for folding a fold is disclosed. At the folding device a substrate to be folded is pushed into an inlet roller nip of folding rollers rotating in opposite directions by a folding knife for forming a fold. The folded-away substrate is transferred from the folding rollers to a belt line guided about the folding rollers and consisting of transport belts for the purpose of onward transporting the folded product. The folding roller in the regions in axial extension in which at least one transport belt at least partially wraps the folding roller includes at least one rubber-elastic insert.

A method for controlling a printing process is disclosed. The method includes printing a printing material by a printing unit on a basis of data of a prepress stage. A printed result on the printing material is compared with a desired value and a correction value is derived from the comparison. The data of the prepress stage is corrected with the correction value.
A method and device for processing printed products made of multiple paper sheets is disclosed. The paper sheets are moved in the direction of a leading open edge and the paper sheets are connected to each other in a detachable manner in the region of the edge.
A web press, in particular a variable format book web press, variable format newspaper web press, or variable format periodical web press, has printing units having printing devices or groups of printing devices for applying ink to a paper web. The printing devices or groups of printing devices are constructed without rotating impression cylinders and are designed to apply ink to the paper web in a noncontacting manner.
