Patent number: 7690300Abstract: A method for producing a security document having printed image 1 produced by steel intaglio printing and embossed microstructures 2 of an order of magnitude of less than 100 microns is carried out by one printing plate 8 on which both the steel intaglio structures and the microstructures are present. The parts of the microstructures closest to printing plate surface 9 are located 20 to 100 microns below the printing plate surface so that they are not touched and destroyed by the wiping cylinder. Alternative methods for producing a steel intaglio printing plate with integrated microstructures are provided. The microstructures can be used for embossing a diffractive relief or a blind embossing.Type: GrantFiled: May 7, 2007Date of Patent: April 6, 2010Assignee: Giesecke & Devrient GmbHInventors: Eckhard Braun, Reinhard Plaschka

Patent number: 7267053Abstract: The invention relates to a delivery device for a sheet-processing machine. The object of the invention is providing a delivery device on a sheet-fed rotary printing machine, that can be universally used and permits quality control of the printed and/or laminated sheets. to this end the delivery device includes rotating sheet feeding system 5 supplying the printed sheets to a first delivery stack 9 and with a drum 7 acting as a turnout point in front of this delivery stack 9 in the transport direction 2 for selective sheet removal. The drum 7 is allocated to the sheet feeding system 5. A vacuum table 14 coupled with a pneumatic system and with at least one rotating suction belt for suctioning, transporting, and positioning a sheet is arranged downstream from the drum in its rotational direction. At least one quality control device 12 for inspecting the sheet is arranged at a distance to the vacuum table 14, with the second delivery system 8 being arranged downstream from the vacuum table 14.Type: GrantFiled: May 2, 2003Date of Patent: September 11, 2007Assignee: MAN Roland Druckmaschinen AGInventors: Ulrich Beitel, Eckhard Braun, Rolf Martin Lange

Method for producing laser-writable data carriers and data carrier produced according to this method
Patent number: 7252239Abstract: The invention relates to a method for producing a data carrier having a laser-markable layer and a transparent optically variable layer overlapping therewith at least in certain areas, wherein visually visible markings that at least partly overlap with the optically variable layer are produced in the laser-markable layer after the application of the optically variable layer. The invention further includes a data carrier produced by the method and a semifinished product, such as a data carrier blank, that is provided for processing by the method.Type: GrantFiled: February 22, 2001Date of Patent: August 7, 2007Assignee: Giesecke & Devrient GmbHInventor: Eckhard Braun -

Patent number: 7040663Abstract: The invention relates to a document of value such as a paper of value or ID card with a security element having an optically variable material. Said optically variable material conveys different color effects at different viewing angles. Additionally, the security element has at least one machine-readable feature substance that does not impair the visually visible optically variable effect of the optically variable material.Type: GrantFiled: February 22, 2000Date of Patent: May 9, 2006Assignee: Giesecke & Devrient, GmbHInventors: Reinhard Plaschka, Eckhard Braun, Wittich Kaule

Publication number: 20060011078Abstract: The invention pertains to a delivery unit on a sheet-fed processing machine, preferably a sheet-fed printing or sheet-fed varnishing machine. The aim of the invention is to provide a delivery unit of this type such that permits in-line transport of printed and/or varnished sheets to at least one additional production line. To this end, the delivery unit 1 includes an endless revolving sheet conveyor system 5 that conveys the sheets to a first delivery stack 9 and a sheet withdrawal drum 7 that functions as a diverter for transferring sheets to a second stacking system. The sheet withdrawal drum is arranged upstream of this delivery stack relative to the conveying direction. A sheet transport system 20 is arranged downstream of the drum 7 and a folding module 12 is arranged downstream of the sheet transport system in the rotational direction 10 of the drum.Type: ApplicationFiled: May 2, 2003Publication date: January 19, 2006Applicant: MAN Roland Druckmaschined AGInventors: Ulrich Beitel, Eckhard Braun, Rolf Lange

Patent number: 6283509Abstract: A data carrier with an optically variable structure is described having an embossed screen which is combined with a coating contrasting with the surface of the data carrier in such a way that different optically variable effects occur at different angles. Embossed screen and/or coating are executed in such a way that especially striking or additional effects occur which are suitable for determining the authenticity of the data carrier but cannot be reproduced, or reproduced true to the original, with the help of copying machines.Type: GrantFiled: February 28, 2000Date of Patent: September 4, 2001Assignee: Giesecke & Devrient GmbHInventors: Eckhard Braun, Johann Muller, Reinhard Plaschka, Franz Daniel
