  • Patent number: 6934041
    Abstract: The invention relates to a method and apparatus for minimizing the influence of register differences in multicolor printing, in particular in digital printing processes, register values (1) in the transport direction (2), which are different transversely with respect to this direction being set to a value between the extremes (3, 3?). The invention is intended to carry out a development such that the influence of register differences on the image quality can be minimized reliably and to a great extent. This is achieved by a number of individual values of the register values (1) being measured and an average value (4, 4?) being determined from these and brought into alignment with the average value (4, 4?) from at least one further color printing unit (5, 5?, 5?, 5??).

  • Patent number: 6522857
    Abstract: A method and apparatus for setting registration in a multicolor printing machine (1) having a number of exposure devices (2, 2′, . . . ) for the digital production of color separations (3, 3′, . . . ), the actions of setting up and combining the color separations (3, 3′, . . . ) being controlled, in order to set registration, such that in-register prints are achieved, influencing variables (4, 4′, 4″) which are caused by the printed pages and have an influence on registration being taken into account in setting up and combining the color separations (3, 3′, . . . ) before the onset of a change in said influencing variables. Therefore, no interruption of the printing process between two different printed pages (33, 34) is necessary.

  • Patent number: 6519423
    Abstract: A method and apparatus for setting registration in a multicolor printing machine for the digital production of color separations, the actions of setting up and combining color separations being controlled when printing substrates of a different grade are fed in, in order to correct registration setting. In the event of a change in the printing substrate grade, the influence of this change on registration can be compensated for optimally before the printing substrate (16) is fed to the printing process. When the printing substrate grade is changed, the influence of all the properties of the printing substrate (16) that are relevant to registration is taken into account directly as the change is implemented, by correction values (4, 4′, . . . ) for the printing substrate (16) that are available before printing is carried out.

  • Patent number: 6493012
    Abstract: A method and apparatus for setting register on a multicolor printing machine (1) having color printing units (6, 6′, 6″, 6″) allocated to various printing inks and having image cylinders (2, 2′), equipment (3, 3′) for producing images, in particular electrostatic latent images, on the image cylinders (2, 2′, . . . ), a carrier (4) for printing substrates (15) and image transfer points (5, 5′, 5″, 5′″) for the transfer of the color separations (7, 7′, . . . ) from the color printing units (6, 6′, 6″, 6′″) to the printing substrates (15), an allocation of the image productions (11, 11′) on the image cylinders (2, 2′, . . . ) to the printing substrates (15) being carried out in order to achieve coincidence of register of the color separations (7, 7′, . . . ) in the print. This is achieved by a time-independent allocation of the positions of the image productions (11, 11′, . . .
