Publication number: 20120240801Abstract: Printing material printing processes generate a raster bit map manipulated by matrix manipulation to compensate for geometrical distortions of the printed image on the printing material. First of all, the same correction functions are used for following raster bit maps, if the intention is to dispense with the imaging of test printing formes. Measuring marks are also printed, while printing is underway, at fixed positions on a sheet to establish any present register defects. Different repeat configurations for follow-up printing means that it is no longer possible for the measuring marks to be provided at the same positions. The ascertained deviations are used to interpolate adjusted deviations at the first positions for the first measuring marks to make it possible to use the second measuring marks at the shifted positions. Further technical measures are then implemented on this basis. A printing system for printing a printing material is also provided.Type: ApplicationFiled: March 26, 2012Publication date: September 27, 2012Applicant: HEIDELBERGER DRUCKMASCHINEN AGInventors: EBERHARD REDMER, GĆNTER STREITMATTER

Publication number: 20110192304Abstract: An apparatus for registering a printing plate includes a support surface. A first registration member provides an electrical signal to the printing plate when contact is established between the first registration member and a first edge of the printing plate. Each registration member in a set of two or more registration members receives the electrical signal provided to the printing plate when contact is established between an edge of the printing plate and the registration member. A set of two or more sensors detects a presence of the electrical signal received by a registration member. A plurality of actuators is operable for moving the printing plate towards a registration member. A controller determines a presence or absence of contact between the printing plate and a selected registration member based on information provided by each sensor. The controller selectively operates at least one of the actuators to move the printing plate towards the selected registration member.Type: ApplicationFiled: February 5, 2010Publication date: August 11, 2011Inventor: Ryan K. Hines

Patent number: 7971530Abstract: The invention relates to a method and a device for positioning a flexible printing plate on a carrier, comprising the following steps of: placing on a table the flexible printing plate for positioning; determining the position of the printing plate by means of a visual display device; and depending on the position, moving the printing plate to its end position on the carrier, wherein the position of the carrier is sensed in the vicinity of the final position and the carrier is moved to its end position depending on the position sensed in the vicinity of the final position. The positioning takes place much more accurately as a result of these measures.Type: GrantFiled: March 23, 2005Date of Patent: July 5, 2011Assignee: AV Flexologic B.V.Inventor: Petrus Johannes Marie Otten

Patent number: 7966935Abstract: A method for registering a rotary press for a printing process, in which ānā inking systems (Fn) each produce monochrome printed images and print one on top of the other thereby producing n-colored printed images, includes producing the images of a printed material with at least one sensor station, recording information on rotary movements of printing plate cylinders (Dn), and using the images and the information to produce correction signals which actuate the cylinders until a deviation of the images of the respective inking systems from a desired position on the material lies within a defined range of tolerance values. During the registering method, one printing plate cylinder at a time is in the printing position, the sensor station produces the printed images, and the correction signals are obtained based on the image produced by the respective cylinder and the information on the rotary movements of at least one cylinder.Type: GrantFiled: January 19, 2006Date of Patent: June 28, 2011Assignee: Windmoeller & Hoelscher KGInventors: Manfred Loddenkoetter, Martin Kruempelmann
