  • Method for carrying out a production change on a printing press with automated change of a printing plate
    Patent number: 7347144
    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.

  • Control station for a printing press
    Publication number: 20080062419
    Abstract: A control station for a printing press, includes at least one true color monitor for displaying at least one soft proof serving as a color reference for printed copies printed during the printing process, and at least one standard light source for at least partial illuminating the control station to allow visual comparison, independent of room lighting, of a printed copy with the soft proof serving as the color reference. The luminosity produced by the at least one standard light source is variable, so that the luminosity produced by the at least one standard light source can be adjusted to match a brightness achievable on the true color monitor to match a contrast achievable on the true color monitor during the display of the soft proof.
