  • Patent number: 9387665
    Abstract: The in-register arrangement of at least two printing plates on at least two plate cylinders of a printing press, with respect to each other, is accomplished. Settings for a temperature of a printing plate, which is arranged on one of the plate cylinders or of a cylinder barrel of the plate cylinder or of a temperature control assembly, which interacts with the printing plate or the at least one printing cylinder, are determined depending on a printing image which is printed onto a printing material. One temperature of the printing plate or of the cylinder barrel or of the temperature control assembly is changed according to the settings in such a way that subsequently, an image form element, which is arranged on the printing plate, and an image form element, which is arranged on another of the printing plates, are situated in a predefined relative position with respect to one another, at least in an axial direction relating to a plate cylinder.

  • Patent number: 9242452
    Abstract: A printing plate is arranged on a plate cylinder having a channel, in which front and rear clamping devices are located. The rear clamping device forms part of a slide positioned inside the channel and which can move towards the front clamping device. The slide is first moved, together with a rear end of the printing form that is fixed into the rear clamping device, towards the front clamping device. At least one rear spacer is then adjusted to a position relative to the slide that defines a specific distance of the rear clamping device from a second channel wall. A tensioning drive is subsequently deactivated and the slide, together with the rear clamping device, are held in position along the tensioning path by the force exerted by the tensioned printing form, that force pressing the slide against the second channel wall by the rear spacer of the slide.

  • Patent number: 8943967
    Abstract: A method of mounting and adjusting a printing plate on a plate cylinder of a multicolor offset printing press is described. The printing plate is clamped between front and rear clamping bars, the rear clamping bar being movable under the application of a tensioning force and occupying, upon clamping of the trailing end of the printing plate, a tension-release position. Tensioning of the printing plate is carried out by initially applying a nominal tensioning force to the rear clamping bar. A print register of the tensioned printing plate is then measured and compared to a target print register to determine a corrected tensioning position of the rear clamping bar corresponding to the target print register. The tension of the printing plate is thereafter released. The correct tensioning position is set as new reference position of the rear clamping bar before or after tensioning again the printing plate.
