Abstract: Printing material printing processes generate a raster bit map manipulated by matrix manipulation to compensate for geometrical distortions of the printed image on the printing material. First of all, the same correction functions are used for following raster bit maps, if the intention is to dispense with the imaging of test printing forms. Measuring marks are also printed, while printing is underway, at fixed positions on a sheet to establish any present register defects. Different repeat configurations for follow-up printing means that it is no longer possible for the measuring marks to be provided at the same positions. The ascertained deviations are used to interpolate adjusted deviations at the first positions for the first measuring marks to make it possible to use the second measuring marks at the shifted positions. Further technical measures are then implemented on this basis. A printing system for printing a printing material is also provided.

Abstract: A method for the usage-controlled updating of a software product for a machine using a computer, includes collecting key operating figures on the usage of the software product in the form of a customer-specific data record by using the computer, saving the data records on the computer, determining the components of the software product that require an update by evaluating the data record, and implementing the determined updates on the computer.

Abstract: A method for printing combined jobs having different blanks on a printed sheet includes obtaining area coverage values or inking zone presetting values for printing presses, with which the blanks are printed, from image data of the printed sheet. The area coverage values from an earlier job are compared with those from a subsequent job, in which the number, the configuration or the type of at least one blank differs from the corresponding value from the earlier job. The configuration of the blanks on the sheet is changed if the difference in the area coverages exceeds predefined values. An installation for carrying out the method is also provided.

Abstract: A method for exposing a printing form includes the following steps: A matrix having device-dependent image information is provided on a computer for supplying data to a printing form exposer. The matrix having device-dependent image information is transformed in a matrix manipulation device into a corrected matrix having device-dependent image information. A printing form is exposed in the printing form exposer with the image information in accordance with the corrected matrix. Here, a first part of the transformation rule for producing the corrected matrix in a first zone of the matrix is defined as a function of the area coverage of the first zone, and a second part of the transformation rule for producing the corrected matrix in a second zone of the matrix, which is different from the first zone, is defined as a function of the area coverage of the second zone, the area coverage in the first zone and the area coverage in the second zone being different from each other.

Abstract: A method and an apparatus are provided for correcting geometric errors during a transfer of a printing image to a printing material. For the purpose of correction, a raster bitmap is fed to a matrix manipulation device, which distorts the raster bitmap. The problem with the distortion is that areas such as edge marks are also distorted. In order to avoid those undesired distortions, a protected area determining device for determining a protected area within the raster bitmap and/or the master print, and a protective element for preserving the content of a protected area within a raster bitmap, are provided.
