  • Apparatus and method for detecting a predetermined pattern on a moving printed product
    Patent number: 7199387
    Abstract: An apparatus and method for detecting a relatively narrow predetermined pattern, such as a trigger mark, on a moving printed product uses a plurality of sensor elements arranged linearly in an array and a switching apparatus for selecting a properly located subset of the sensor elements for detecting the predetermined pattern. During the operation of the apparatus, only those signals from sensors in the selected subset are checked continuously for the occurrence of a signal pattern corresponding to the predetermined pattern. Each time the predetermined signal pattern is found in the output signal from a sensor within the selected subset, a detection signal is generated. The lateral shifting of the predetermined pattern over time may be monitored by the selected sensors, and the selection of the subset of sensors for the continuous evaluation may be changed in response to the lateral shifting.

  • Method for carrying out a production change on a printing press with automated change of a printing plate
    Publication number: 20070022893
    Abstract: An automated method is provided for carrying out a production change, which is specific to the printing plate, on a printing press. After a first print job is printed on a printing press, the printing of the first print job is stopped automatically after a predefined print run level has been reached or another termination criterion for the first print job has occurred. Parameters required for printing a second print job which follows the first print job are loaded automatically by the printing press. Before or after the parameters of the second print job are loaded, a printing plate change is automatically carried out on the printing press, thus achieving production readiness for the second print job. The second print job is then either started automatically, or a production readiness signal for the second print job is generated automatically.

  • Apparatus and method for acquiring and evaluating an image from a predetermined extract of a printed product
    Publication number: 20070007432
    Abstract: An apparatus for acquiring and evaluating an image of a predetermined extract of a printed product removes the effects of scattered light to improve the accuracy of image evaluation. The apparatus uses a camera that has an electronic image sensor with a two-dimensional arrangement of sensor elements. An aperture stop is arranged in the beam path of the camera for shadowing a predetermined part of the image sensor. When an acquired image is read from a part of the image sensor that is not shadowed, corresponding readings from the shadowed portion of the sensor are subtracted from the acquired image to obtain intensity signals corrected for scattered light.

  • Web-fed rotary press having sleeve-shaped printing blankets
    Publication number: 20070006753
    Abstract: A web-fed rotary offset press is disclosed. The press is designed for using sleeve technology, it being possible for sleeve-shaped rubber blankets to be pushed onto the rubber-covered cylinders in the axial direction. Finite printing plates are placed onto the plate cylinders in a conventional manner, it being possible to fix the ends of the finite plates in slots of the plate cylinders. Rubber-covered cylinders are used which have a double circumference, while the plate cylinders have a single circumference. As a result, the rigidity of the cylinder system is increased substantially, with the result that a stable web run and in-register printing are possible in wide machines over 1400 mm, without it being necessary for modifications to be performed on the cylinders or the compressibility or thickness of the rubber layers of the sleeves to be changed in the axial direction.
