摘要:
A method and apparatus for fitting a printing plate to a plate cylinder where the printing plate is bent into a circular shape and fixed in this form by leading and trailing legs of the plate being firmly connected to each other. The printing plate shaped in this way is subsequently axially pushed onto the plate cylinder from the free side of the plate cylinder.

An ink transport roller (1) which may be used universally for panorama printing and printing of multiple colors next to one another. The roller has a recess (2) in an area between the colors which may be optionally opened or closed depending upon whether the roller is to be used for printing multiple colors next to one another or panorama printing, respectively.

A blanket clamping device for clamping a blanket mounted on a transfer cylinder of an offset rotary printing machine. The blanket is clamped by clamping rails mounted at an angle relative to each other in the clamping duct. In the middle between the clamping rails is arranged at least one screw which is screwed into the body of the transfer cylinder and has a truncated cone-shaped head. The clamping rails each have a step on a surface facing the at least one screw. Movement of the clamping rails out of the clamping duct is prevented by engagement of the steps with the truncated cone-shaped head.

The invention relates to a method for printing printed material which is individualized with logistical printed image elements, wherein at least one printed image, particularly a static printed image, which is printed in a printing machine, is individualized by technically adding at least one dynamic logistical printed image element. According to the invention, data of the/each dynamic logistical printed image element is combined in such a way that the/each printed image and the/each logistical printed image element are automatically updated by comparing data between a data bank provided by a print job user and a data bank provided by a logistics provider prior to printing the printed material individualized with the/each logistical printed image element.

The invention relates to a method for producing an RFID label using a printing method. The aim of the invention is to apply the required parts to the label in a simple manner, and preferably also to protect the antenna from mechanical damage. To this end, at least part of the antenna required for the operation of the label and part of the oscillating circuit is applied to the stock by means of sheet-fed offset printing or directly or indirectly by means of a relief-printing plate. In order to protect the oscillating circuit from damage, the application surface thereof is lowered, or the oscillating circuit and the antenna are lowered into the stock after the application process.
摘要:
A method for erasing the surface of a rewritable printing form within a printing press in which the form cylinder carrying the printing form rotates during the erasing process, wherein the erasure is performed over the course of two main erasing steps. That is, a first main erasing step is performed during the run-down of the form cylinder upon completion of a printing order, whereupon the second main erasing step performed, for which purpose the form cylinder is again driven after it has run down.
摘要:
A press unit of a press, in particular a web-fed rotary press, having at least one printing unit, the printing unit having at least one cylinder module comprising a form cylinder and a transfer cylinder and an inking module comprising an inking unit and, preferably, a damping unit. The inking module of the printing unit is arranged laterally beside the cylinder module of the printing unit, it being possible for the inking module of the printing unit to be moved translationally relative to the cylinder module of the printing unit in the axial direction of the cylinders of the cylinder module, in order to move the inking module of the printing unit between a printing position and a maintenance position.
摘要:
A method for operating a printing press for carrying out a forme change and a format change on a sleeve-based printing unit of the printing press, in which a rewritable or erasable printing sleeve is used as printing forme includes setting images on a printing sleeve outside the printing unit of the printing press, wherein the printing sleeve which has images set on it outside the printing unit is positioned on a forme cylinder of the printing unit together with a spacer sleeve which is adapted to the format to be printed, for carrying out the forme change and format change.
摘要:
A method for producing a printing plate, especially inside a printing press, wherein a printing plate with a rewritable surface is provided, and wherein to produce a permanent as well as an erasable image on the surface of the printing plate, the erasing of the surface and/or the imaging of the surface are carried out with the use of an atmospheric plasma.
摘要:
A printing unit having at least one press unit, the, or each, press unit having at least one form cylinder, a transfer cylinder, an inking unit and preferably a damping unit, and having at least one imaging device for imaging and/or de-imaging a rewritable and erasable printing form positioned on the form cylinder. The, or each, imaging device having at least one laser device for producing at least one laser beam and an optical device for focusing the, or each, laser beam on the printing form. At least the laser device of the, or each, imaging device is arranged at a distance from the respective form cylinder, it being possible for the, or each, laser beam produced by the laser device to be conducted via at least one optical fiber in the direction of the optical device of the imaging device positioned in the region of the respective form cylinder.
