摘要:
A press control desk, having a combined display and operating device is disclosed. The device, firstly, is used for the display of objects, in particular press states and/or press functional elements and/or press operating elements, and secondly, is used for the input of commands and/or operators for a press control system. The device has a plate-like or pane-like projection element forming a projection plane, on which the objects to be displayed, in particular the press states and/or press functional elements and/or press operating elements, can be visualized via a projector by using back projection. The device also has a monitoring device which registers a relative position between the projection element and an input element in order to register commands and/or operators to be input via the input element, and transmits them to the press control system.

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.

The aim of the invention is to simplify the attachment of RFID chips or RFID transponders to packagings. For this purpose, the RFID chips are produced as a single RFID label together with antenna elements that are functionally associated therewith. The chips or transponders can be attached to a packaging by means of corresponding devices during production of the printed material, during a subsequent treatment or finishing process of the printed material, during the preparation of the packaging, during production of the packaging or during filling of the packaging. At the time of attachment, the RFID chips can be tested and initialized. The invention allows to considerably simplify the so far complex processes required to integrate the RFID chips into different types of packaging.
摘要:
A process for the production of a printing form, especially within a printing press, where a permanent and erasable image is provided on the rewritable surface of a printing form by means of the following steps: (a) the preparation of a printing form with a rewritable surface; (b) the all-over application of a rubber coating to the rewritable surface of the printing form; (c) the image data-oriented removal of the previously applied rubber coating; (d) the image data-oriented application of an imaging polymer to the surface in the areas from which the rubber coating was previously removed; and (e) the all-over fixation of the imaged surface.

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.

An offset printing press includes an offset printing unit having a form cylinder, a transfer cylinder, an inking unit, a rewritable and erasable offset printing form positioned on the form cylinder, and at least one image-setting device for at least one of setting and erasing images on the rewritable and erasable offset printing form positioned on the form cylinder. The rewritable and erasable offset printing form has a seamless surface for non-repeating offset printing. An entire surface of the rewritable and erasable offset printing form has a defined roughness adapted to offset printing.
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 inking unit, if appropriate together with the damping unit, can be pivoted with respect to a form cylinder from a printing position into a rest position. The imaging device can be pivoted with respect to the form cylinder from an imaging position into a rest position. The imaging device is pivoted into a rest position when the inking unit and, if appropriate, damping unit is pivoted into the printing position and, when the imaging device is pivoted into the imaging position, the inking unit and, if appropriate, the damping unit is pivoted into a rest position.
摘要:
A printing image is provided on a rewritable surface of a printing form within a press. The steps of providing the image, including erasing the surface, generating the image on the surface, fixing the imaged surface, and conditioning the imaged surface, are carried out in a section-by-section manner over the entire surface, and all the steps, or sub-combinations of the steps, may be carried out in parallel. In the apparatus for producing the printing image, the devices for erasing, imaging, fixing, and conditioning may be mounted on a common platform movable along a longitudinal direction of the printing form to allow the steps to be performed in parallel.
摘要:
A printing machine for multicolor printing which includes a plurality of printing units and a system for transporting and guiding either sheet-type or web-type printable matter through the printing units. The guiding system includes means, such as adhesive, contact pressure, or retaining belts, for maintaining the printable matter on a transfer belt in proper registry during transfer through the successive printing units.
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.
