摘要： A process for the treatment of an erasable lithographic printing plate, includes treating a used or unused printing plate with an erasing composition to clean the printing plate, laser imaging the printing plate with a polymeric substance, and to provide an image thereon, and fixing the image on the printing plate. Further, the printing plane has applied thereto any one of a heat-curable and water-soluble substance, if desired, immediately after the laser imaging, or a water-soluble substance immediately after the laser imaging, or a heat-curable and water-soluble substance immediately after the laser imaging, followed by warming of the printing plate. The water-soluble substance or the heat-curable and water-soluble substance is washed off using a solution essentially consisting of water before printing.

摘要： A method of producing a printing plate on a cylindrical printing-plate carrier in a rotary printing press uses a digital imagesetting unit and a raster image processor. The method includes subdividing the printing-plate carrier by computation in terms of its width and axial length into at least two circumferential subareas. Then an actual transfer characteristic curve for each subarea is determined and each actual transfer characteristic curve is compared by computation with a predetermined desired printing characteristic curve to find a deviation of the actual transfer characteristic curve from the desired characteristic curve of each subarea. The method further includes calculating a correction to compensate for each deviation; receiving a digital image data in a first data format using the raster image processor, the first data format independent of the printing press; converting the digital image data into machine-specific image data using the raster image processor, the machine-specific image data including the position and the tonal value in the form of a bitmap; applying the correction for a predetermined desired printing characteristic curve for the edition print to the machine-specific image data using the raster image processor; and supplying the machine-specific image data using the raster image processor to the imagesetting unit.

摘要： The image subject to be transferred is applied in preformatted form to at least two printing formes in the form of segment-like image data in a row and column arrangement, in such a way that a first portion of information from each segment of the image subject (information (a) with appropriate index features) is provided on a first printing forme, and a second portion of information from the corresponding segment of the image subject (information (b) with appropriate index features) is provided on a second printing forme. As a result of synchronous rolling of the printing-forme cylinders, the portions of information are assembled to form complete information ( with the respectively combined index features) for each segment of the image subject on the printed page. For each printing-forme cylinder revolution, the index features for each segment of the image subject (information ) are recombined step by step in the manner of a permutation, so that each printed segment constitutes a unique print.

摘要： Inking unit rolls include at least one ink applicator roll, which rotates in an ink fountain filled with printing ink and picks up printing ink from the latter, and a plate cylinder, which serves as a printing plate carrier and onto which ink can be transferred, directly or indirectly, by the ink applicator roll. The short inking unit is therefore equipped with a small number of inking unit rolls and, at the same time, nevertheless ensures a uniform, homogeneous application of ink to the plate cylinder, that is to say the ink splitting on ink-carrying rolls of a short inking unit for a rotary printing machine is improved. At least one of the inking unit rolls is provided, at least on its surface, with a coating having powerful microdipoles, in particular made of ferroelectric material. This circumferential surface is assigned electric means in order to produce an electric field by means of a DC/AC voltage, in order to polarize and depolarize the microdipoles of the circumferential surface in the form of a homogeneous or periodic charge image, so that an ink layer resting on it is given a desired electric roughness.
