摘要:
Variable-format web-fed offset printing machine having printing-unit cylinders comprising core cylinders to which compressed air can be applied and onto which intermediate sleeves can be pushed axially and shrunk on radially. Each intermediate sleeve includes a carrier layer whose inner face rests on the core cylinder, a compressible intermediate layer, a transition layer, and a variable-thickness bridging layer, which ends with a covering layer to which a further surface like a printing plate or a rubber blanket can be fitted.

A printing unit for a web fed rotary printing machine is provided including a machine frame support, two sets of printing unit cylinders, carriages, drive motors and guide elements. The two sets of printing unit cylinders, include a plurality of outer printing unit cylinders and a plurality of inner printing unit cylinders. Each carriage corresponds to one printing unit cylinder for rotatably mounting its corresponding printing unit cylinder on the machine frame support. There is a drive motor for each carriage. Two sets of guide elements are arranged on the machine frame for determining a travel setting of the plurality of carriages along the machine frame support. The guide elements for the outer cylinders are arranged on the frame support in an orientation different than the guide elements for the inner cylinders so that movement of the outer printing unit cylinders is in a different direction than movement of the inner printing unit cylinders. Optionally, the printing unit accommodates additional printing devices that are moveable in relation to their corresponding cylinders and vice versa.
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 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 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.

A printing unit is provided for a web-fed rotary printing machine, having a plurality of cylinders with associated drive motor, an additional device for printing an at least two guide elements. At least one cylinder is a plate cylinder. At least one guide element corresponds to the plate cylinder and is operably arranged in the printing unit for determining a setting path of the corresponding plate cylinder relative to the other cylinders. This guide element extends as far as the additional device for printing.

Disclosed is a method for producing an RFID label with the aid of a printing process. The aim of the invention is make it easy to apply the parts required onto the label while completing the label in a simple manner. Said aim is achieved by applying at least one portion of the antenna and the resonant circuit required for the function to the printing material by means of sheet-fed offset printing or directly or indirectly with the aid of a relief printing plate. The resonant circuits or chips are applied individually or to a packaging that is to be created or filled in the same alignment once several copies of the labels have been produced on one sheet and have been separated therefrom.

The invention relates to a method and device for printing a fabric. The printable fabric (11) is moved through at least one printing mechanism (10) in order to print a static or non-variable printing image. According to the invention, the printable fabric (11) is moved through at least one printing device (12,13) which is coupled in-line to the printing mechanism (10) in order to individualize the static pattern with at least one dynamic or variable printing image.

A web-fed press is provided. The web-fed press includes a reel carrier and a plurality of printing units arranged one after another for printing a printing material with a static printed image. The web-fed press includes a folder superstructure that is arranged after the printing units and a folding unit arranged after the folder superstructure. An imprinting unit for individualizing the static printed image with, in particular, changing text and/or image constituents is integrated into the web-fed press in the region of the folder superstructure.
