Publication number: 20170017201Abstract: A plate for creating holograms or other light-bending or diffractive microstructures on web-shaped or sheet-shaped printing substrates includes a relief for a relief printing process. The relief is formed of one or more raised dies and one or more adjacent depressions. A non-metallic microrelief for printing or embossing the microstructure is provided exclusively on the dies. The plate may be manufactured in a process in which a primary plate has a negative of the microrelief and the microrelief is created by molding the negative.Type: ApplicationFiled: July 15, 2016Publication date: January 19, 2017Inventors: MARTIN SCHMITT-LEWEN, BERNHARD BUCK, MICHAEL THELEN

Publication number: 20160067973Abstract: A method for cleaning ink residues off an inkjet print head includes applying a cleaning agent to a surface of the inkjet print head and then removing the cleaning agent from the surface. The surface has nozzle openings. The cleaning agent is applied to the surface as a gel, in particular as a gel that has a purely physical cleaning effect. This allows inkjet print heads to be cleaned in a simple way with very good results while avoiding the disadvantages connected with liquid cleaning agents, such as dripping off.Type: ApplicationFiled: September 10, 2015Publication date: March 10, 2016Inventor: BERNHARD BUCK

Patent number: 9242449Abstract: An offset printing method includes creating halftone dots corresponding to a printed image and formed of printing ink, on a surface of a transfer cylinder and transferring the halftone dots to a printing substrate while the transfer cylinder rotates about its longitudinal axis. A halftone value in a printed image on the printing substrate is adjusted to a desired value by modifying a halftone dot size. The offset printing method improves the quality of the printed image by increasing the halftone dot size by a desired amount by providing a relative offset between a device that creates the halftone dots and the surface of the transfer cylinder.Type: GrantFiled: April 29, 2013Date of Patent: January 26, 2016Assignee: Heidelberger Druckmaschinen AGInventors: Axel Hauck, Bernhard Buck

Patent number: 9079388Abstract: A method and an apparatus control a printing press having a plurality of printing units, a plurality of cylinders which are coupled mechanically to one another and a control computer for controlling at least one drive motor which drives the mechanically coupled cylinders. A torsion model is stored in the machine computer for describing the torsion state of the cylinders in the printing press which are rotatably coupled mechanically to one another, as a function of at least one measurable operating parameter or at least one variable of the printing press which is known to the machine computer. A control of the printing press is performed by the control computer on the basis of the values which are calculated by the torsion model.Type: GrantFiled: February 16, 2007Date of Patent: July 14, 2015Assignee: Heidelberger Druckmaschinen AGInventors: Stefan Schreiber, Bernhard Buck, Werner Joss, Malte Seidler

Patent number: 8910573Abstract: A method for controlling an inking unit of a printing press, includes resetting an ink metering element from first to second metered quantities for an intended inking level. The metering element is set to a temporary, third metered ink quantity by a control unit, for a time interval, during a non-steady phase of the inking unit before reaching the intended level. A value of a variable characterizing the inking state of printing material is determined and a plurality of sets of values for the variable are predefined, into which the determined value can be grouped. The temporary metering quantity is carried out: at a first rate and/or during a first time period if the value of the variable lies in a first set of values, and at a second rate and/or in a second time period if the value of the variable lies in a second, different set of values.Type: GrantFiled: May 6, 2010Date of Patent: December 16, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Peter Elter, Nikolaus Pfeiffer, Bernhard Buck

Patent number: 8794148Abstract: A printing press includes an assembly and a cam mechanism for moving at least one part of the assembly. A cam of the cam mechanism has a curvature course with points, in particular bends or jumps, which are not constantly differentiable within a movement region of the cam. The cam mechanism can include an actuator for the temporal displacement of jolts which are induced by the points that are not constantly differentiable to the at least one part of the assembly. An adaptation of the movement which is produced to the operating state of the printing press is possible, with the result that a considerable reduction can be achieved in vibrations for all printing speeds.Type: GrantFiled: January 23, 2009Date of Patent: August 5, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Martin Baureis, Bernhard Buck, Siegfried Kurtzer, Stefan Mutschall, Henning Niggemann, Malte Seidler

Patent number: 8763529Abstract: A method of compensating for vibration-induced circumferential-register errors in a sheet-fed printing press includes compensating for at least one vibration-induced deviation of an actual angular position of a cylinder from a nominal angular position by adjusting the circumferential register of at least one printing unit, in particular of the cylinder. For this purpose, the current vibration state of the sheet-fed printing press is determined, the effect of the determined vibrations of an integer order on a position of color excerpts on a sheet of printing material is calculated, and the compensating circumferential-register adjustment required in accordance with the result of the calculation is carried out. A sheet-fed printing press for carrying out the method, is also provided.Type: GrantFiled: October 25, 2007Date of Patent: July 1, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Bernhard Buck, Stefan Schreiber, Malte Seidler

Patent number: 8375856Abstract: In a method for compensating an oscillation which has a frequency spectrum with a number of discrete frequency components in a printing press, at least one counter torque is introduced into the printing press in order to compensate for at least one discrete frequency component of the oscillation. A first group of one or more frequency components are compensated for by introducing one or more previously determined counter torques, and a second group of one or more frequency components is compensated for by introducing specific counter torques as a function of a measurement, carried out during the operation of the printing press, of at least one signal which contains at least the one or the plurality of frequency components.Type: GrantFiled: March 26, 2007Date of Patent: February 19, 2013Assignee: Heidelberger Druckmaschinen AGInventors: Bernhard Buck, Eric Knopf, Matthias Nöll, Stefan Schreiber, Malte Seidler, Detlef Strunk

Patent number: 7453223Abstract: For the active compensation of oscillations in a machine which processes printing material, a signal which contains an oscillation of the machine or of a part of the machine is measured and at least one counter torque is introduced into the machine to reduce the oscillation. At least one measure for a ratio between the amplitude of the uncompensated oscillation and the amplitude of the counter torque necessary for complete compensation is compared with a threshold value. The counter torque is determined in a first functional relationship with the oscillation if the measure is greater than the threshold value, and the counter torque is determined in a second functional relationship with the oscillation, if the measure is smaller than the threshold value. In the machine, a regulating device is operated in a first or second operating mode in dependence on the measure of the ratio.Type: GrantFiled: January 25, 2007Date of Patent: November 18, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Bernhard Buck, Eric Knopf, Matthias Nöll, Malte Seidler, Detleff Strunk, Uwe Tessmann
