Abstract: A method of inspecting images on printed products by a computer in a printing machine. Printed products are recorded and digitized by an image sensor of an image inspection system in the course of the image inspection process, and the computer compares them to a digital reference image. If deviations are found, the defective printed products are removed. The computer analyzes the deviations found in the course of the image inspection process together with further data from other system parts and from the machine, determines specific defect classes and the causes thereof based on the defects by machine learning processes, assigns the defects found in the image inspection process to the defect classes in a corresponding way, and displays the classified detected defects with their defect classes and causes to an operator of the machine so that the operator can initiate specific measures to eliminate the defect causes.

Abstract: A method for inspecting printed products of a machine for processing printing substrates includes recording and digitizing produced printed products by using at least one image sensor and analyzing the printed products by using a computer to find potential defects. Defects in the printed products are detected by the computer by comparing the recorded and digitized printed image with a digital reference image, analyzing occurring deviations, and marking defective printed products in a manner suitable for removal. The computer spatially subdivides every digitized printed image into regions with deviations, calculates the time required to analyze every one of the regions, and terminates the analysis of a digitized printed image when the time required to analyze the regions exceeds a predefined value of time per digitized printed image.

Abstract: An adjustment and stabilization unit (1), such as for a weapon, includes a movable platform (3), a rotational mass (2) mounted on the platform and stabilized in inertial space, and an adjustment drive (6) for adjusting the rotational mass. The adjustment drive includes a driving device (7) connecting the adjustment drive with the rotational mass, a force-sensing device (16) for measuring torque, and at least one stabilization control circuit for controlling the rotary adjustment drive by means of the measured torque. The force-sensing device (16) has an annular design and is arranged between the platform (3) and the adjustment drive (6). The driving device has a shaft (10) that extends through force-sensing device (16). The force-sensing device measures the torque transmitted between the adjustment drive and the platform, and being transmitted to the adjustment drive as a result of an acceleration of the rotational mass.

Abstract: A raster generation system for a printing machine with an image-setting unit in which the system has at least one raster processor for generating raster data from raw image data, and a memory for storing the raster data. In order to have a raster generation system with a high operating speed in spite of the simple components that are used, the memory for storing the raster data is formed by a raster memory with random access, and the raster processor stores the raster data column by column in the raster memory.

Abstract: A method for mounting a printing master on a printing form cylinder includes readying a new print job with a printing-image length by releasing an unwinding spool, activating an unwinding spool drive for moving the printing master a length in circumferential direction of the cylinder on the circumferential surface by drawing the printing master to a rewinding spool and braking the unwinding spool for building tension. A preceding job image start is located on the surface facing the rewinding spool. A control device activates the unwinding spool drive and, before activation, data is produced in the control device regarding the length to be spooled forward, and the spools are fixed, after advancing the printing master a length, for insuring tension. A value is determined for the printing master length to be spooled forward, being at most the printing image length of the preceding print job plus a printing image spacing.
