Abstract: A method for producing printing formes, which serve for the printing of a substrate web with a seamless or transitionless, endless or format-variable print image in offset print, is disclosed. For each printing color of the print image to be printed, a total separation of the respective printing color is divided over at least two printing formes so that with a first printing forme a first part separation of the total separation and with a second printing forme a second part separation of the total separation can be printed onto the substrate web. The substrate web in first portions can be exclusively printed by the first part separation and in second portions can be exclusively printed by the second part separation. The substrate web in third portions can be printed by the first part separation and by the second part separation in an overlapping or overlaying manner.

Abstract: 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.

Abstract: A method for printing on a substrate, wherein the substrate is printed upon with a plate-based printing process, particularly with an offset printing process, and with a plateless printing process, particularly with an inkjet printing process, inline with the plate-based printing process. According to the invention, a printing resolution of the plateless printing process is determined depending on a printing speed of the plate-based printing process.

Abstract: A method for controlling at least one control parameter from a number of parameters of an inking unit of a printing press is disclosed. Based on at least the control parameter, a value of an ink density on a substrate to be printed by the printing press is calculated by an inking unit model and the calculated value is used as input quantity for controlling instead of an actual value. Here, the calculated value is exclusively calculated based on a number of parameters of the inking unit at least at times.

Abstract: A method and apparatus for printing on a printing material web is disclosed. A rotary offset printing machine includes a printing unit with two plate cylinders and a blanket cylinder. The blanket cylinder prints on the printing material web and the two plate cylinders are arranged relative to each other such that respective images from the two plate cylinders are transferred to an identical position on the blanket cylinder during the printing.

Abstract: A digital printing device for the dynamic printing of a substrate web statically printed in a reel-fed printing press is disclosed. The digital printing device includes a position sensor which measures the substrate web for regulating a print position for the dynamic printing. The digital printing device is provided with a signal from a signal source of the reel-fed printing press. A position sensor control generates a synchronization signal and provides the synchronization signal to a digital printing head control. A speed signal transformer generates a feed signal and provides the feed signal to the digital printing head control. The digital printing head control activates the digital printing head dependent on the synchronization signal and the feed signal.

Abstract: A folding device of a printing press for folding signatures is disclosed. The folding device includes a folding blade cylinder, via which signatures to be folded can be fed to a jaw cylinder arranged downstream of the folding blade cylinder subject to forming transverse folds. A cylinder is arranged upstream of the folding blade cylinder, on which the signatures can be collected in any number prior to the forming of the transverse folds.

Abstract: A cross cutting device of a reel-fed printing press for cutting copies off a printed substrate web through cross cutting of the substrate web is disclosed. The cross cutting device includes at least two cross cutting modules each of which include a cutting cylinder and a counterpart cylinder interacting with the cutting cylinder. Each of the cross cutting modules can be displaced between a working position and a rest position.

Abstract: A printing press control station is disclosed. The control station includes a support and a display element. The display element is a combined display and operating element for displaying and inputting data. The display element can be shifted along the support. Either the display and operating element or an assembly that can be shifted together with the display and operating element or the support or a housing receiving the support, is assigned at least one sensor which senses a lateral distance of the display and operating element or of the assembly from a lateral portion of the support or the housing. The data displayed and input on/in the display and operating element can be automatically adapted to the relative position of the display element relative to the support sensed by the or each sensor.

Abstract: A printing unit cylinder and a sleeve for a printing unit cylinder is disclosed. The printing unit cylinder has an axial end section on the operator's side and a lateral surface having a plurality of openings through which compressed air can be passed so that a sleeve thereby widened can be pulled onto the lateral surface and pulled off of it over the axial end section. A noise reduction structure is provided on the axial end section for reducing the noises generated by compressed air emerging between the sleeve and the lateral surface. The noise reduction structure is equipped to support an inside circumferential surface of the sleeve on the axial end section over at least a portion of its circumference, so that vibrational excitation of the sleeve based on the escaping compressed air is prevented.
