Patent number: 6876378Abstract: An apparatus for producing a printing form which, with little expenditure, permits exact beam alignment and positioning. The apparatus for producing the printing form contains a holder for at least one printing form blank, and at least one imaging module, which can be moved relative to the printing form blank and which contains at least one radiation source which, in order to produce image elements that accept printing ink, is aimed at the surface of the printing form blank and whose beam direction can be adjusted. The imaging module being accommodated in a six-point mounting in three bearing locations, each bearing location containing a spherical element and an associated bearing element and in each case the spherical element rests on it and, in order to adjust the beam direction, at least one element of one bearing location being disposed adjustably.Type: GrantFiled: May 23, 2003Date of Patent: April 5, 2005Assignee: Heidelberger Druckmaschinen AGInventors: Andreas Detmers, Claus Harbach, Bernd Lassen, Sven Mader, Christian Meier, Burkhard Paasch, Lars Paulsen, Markus Uihlein, Bernhard Zintzen

Patent number: 6836740Abstract: A method of determining a relative position of first and second imaging devices includes setting an image of a group of mutually different reference patterns and a basic pattern on an imaging medium, with the second imaging device. Each reference pattern of the group is assigned uniquely to one relative position. An image of at least one test pattern is set over the basic pattern by the first imaging device, for forming a combination pattern. A reference pattern having an area coverage coinciding with an area coverage of the combination pattern is identified from the group of reference patterns. A relative position associated with the identified reference pattern of the group of reference patterns is then identified. A printing form exposer, a printing unit, a printing unit group and a printing press for performing the method are also provided.Type: GrantFiled: January 31, 2003Date of Patent: December 28, 2004Assignee: Heidelberger Druckmaschinen AGInventors: Thomas Köhler, Bernhard Zintzen

Publication number: 20030222970Abstract: A device for producing a printing form includes a radiation source for emitting at least one imaging beam directed to a material whereon an image is to be set. A device is provided for positioning the radiation source relative to and parallel to a surface of the material. A shutter is to be positioned for shielding between the radiation source and the material when an image is not being set on the material.
