Patent number: 8746143Abstract: A method and an apparatus for compensating for inking differences between setpoint color values and actual color values in offset printing presses having at least one inking unit and a control computer. The control computer controls the printing speed of the offset printing press and the temperature control of rollers in the inking unit of the offset printing press. The control computer is set up in such a way that, if an inking difference is detected between the setpoint color values and the actual color values, a combined control operation including a change in the printing speed and the temperature in the inking unit is performed in order to compensate for the inking difference. A printing press having the apparatus is also provided.Type: GrantFiled: October 21, 2010Date of Patent: June 10, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Christopher Berti, Manfred Jurkewitz, Jürgen Rautert

Patent number: 8687207Abstract: A method for determining the optimum procedure for a job change on a printing-material processing machine (10) with at least one control computer. The data of a first machine job is compared to the data of a subsequent machine job using a control computer, and the comparison is used to establish an order of the operations to be carried out during the job change. Also provided is a device for determining the optimum procedure for a job change on a printing-material processing machine (10) with at least one control computer. The control computer is intended to compare the data of a first machine job to the data of a subsequent machine job, and to use the comparison to establish an order of the operations to be carried out during the job change.Type: GrantFiled: September 12, 2003Date of Patent: April 1, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Christopher Berti, Bernhard Buck, Holger Faulhammer, Michael Krueger, Juergen Maass, Sven Mader, Stefan Maier, Kai Oskar Mueller, Matthias Noell, Martin Riese, Bernhard Roskosch

Patent number: 8671838Abstract: A method for color control in printing presses having at least one first color measuring instrument and at least one second color measuring instrument, includes registering at least one first inking zone on a printing material with the first color measuring instrument and registering at least one other, second inking zone on the printing material with the second color measuring instrument. In a first step, a color difference between actual colorations of the first and second inking zones is calculated, in a second step, a color difference between an actual coloration of the first inking zone and a desired coloration of the second inking zone is calculated and, in a further step, the calculated color differences are added and supplied to a color control for the second inking zone.Type: GrantFiled: April 30, 2010Date of Patent: March 18, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Christopher Berti, Wolfgang Geiβler, Werner Huber, Manfred Schneider

Patent number: 6921070Abstract: A method of feeding sheets to a printing-technology machine includes individually separating sheets from a sheet pile, conveying the sheets against movable lays for effecting an alignment thereof, and cyclically conveying the sheets from the lays to the machine. A control device coordinates movement of the lays with the individual separation of the sheets from the sheet pile and onward conveyance of the sheets to the machine. Data related to characteristics of the sheets are processed in the control device for generating actuating signals for a separate, controllable drive system. The lays are moved by the drive system. A device for performing the method is also provided.Type: GrantFiled: November 18, 2002Date of Patent: July 26, 2005Assignee: Heidelberger Druckmaschinen AGInventors: Christopher Berti, Bernhard Buck

Patent number: 6725780Abstract: A method of driving a machine related to printing technology, wherein movable elements forming a kinematic chain are coupled with one another via at least one gear mechanism, includes infeeding torque components by a respective motor of at least one group of two motors, respectively located at least at two elements associated with one another. The torque components are of equal amplitude but have opposite directions of rotation, for suppressing disruptive oscillations at least at the one group of two motors. The amplitude of the torque components is proportional to relative rotation of the two elements associated with one another. Rotary encoders are provided to obtain signals for reproducing rotational positions of the elements.Type: GrantFiled: December 12, 2002Date of Patent: April 27, 2004Assignee: Heidelberger Druckmaschinen AGInventors: Christopher Berti, Bernhard Buck, Holger Faulhammer, Michael Krüger, Jürgen Maass, Sven Mader, Stefan Maier, Kai Oskar Müller, Matthias Nöll, Martin Riese, Bernhard Roskosch
