  • Patent number: 8807033
    Abstract: A print control strip to be applied to printing material during a multicolor printing process, includes multiple measuring fields associated with one ink zone on the printing material. The measuring fields, which are associated with one ink zone, include at least two gray measuring fields. A method of measuring measuring fields in print control strips on printing material with a measuring device and a control unit connected thereto, and a method of controlling metering of ink in offset printing presses including at least one ink metering device in each printing unit and a control unit, are also provided.
    Type: Grant

  • Publication number: 20120279410
    Abstract: A method for determining setting errors in a sheet-fed printing press includes recording a geometry of a printed sheet running through the printing press with an imaging system and comparing the recorded geometry with intended geometries for evaluation. An imaging system oriented substantially perpendicular to a sheet surface at least partly registers visible contours of sheet edges and conclusions are drawn, from measured deviations of the sheet edges in relation to intended contours, as to at least one of the following setting errors of the printing press: a faulty sheet transfer because of an incorrect setting of a gripper bar transporting the sheet, a lifting of the sheet off an impression cylinder because of an incorrect setting of blown air for sheet guidance, or an incorrect radius of the impression cylinder, for example because of incorrectly chosen underlays/cylinder covers.
