Patent number: 6041708Abstract: To improve the control of the inking process in an offset printing machine, color measuring fields provided on printed sheets are evaluated not as heretofore densitometrically but colorimetrically by means of spectral measurements. Spectral reflections are used to match colors, or color coordinates are calculated from them and compared with corresponding set reflections or set color coordinates. The color deviations obtained in this manner are used to control the inking process. For the stabilization of printing runs the spectral reflections are converted into filter color densities and the inking process is controlled on the basis of these color densities in a conventional manner. The control of the inking process using color deviations and control using color density may be superposed upon each other.The process makes it possible to adapt color impressions in delicate locations of importance for the image in the print to the corresponding locations of the proof.Type: GrantFiled: August 22, 1994Date of Patent: March 28, 2000Assignees: Heidelberger Druckmaschinen Atkiengesellschaft, Gretag AtkiengesellschaftInventors: Helmut Kipphan, Gerhard Loffler, Guido Keller, Hans Ott

Patent number: 6026747Abstract: Multiple winding mechanisms are disposed within a single cylinder, such as the plate cylinder of a printing press, and are actuable so as to pay out material across different cylinder segments. For example, the winding mechanisms may be differentially geared to cylinder rotation, such that rotation of the cylinder in a first direction advances material from a first winding mechanism across a first circumferential portion of the cylinder to a second winding mechanism; while rotation of the cylinder in the opposite direction advances material from the second winding mechanism across a second circumferential portion of the cylinder (which may, for example, be diametrically opposed to the first cylinder portion) to the first winding mechanism. Alternatively, material advancement may be achieved by means of a dedicated motor rather than mechanical coupling to cylinder rotation.Type: GrantFiled: January 19, 1999Date of Patent: February 22, 2000Assignee: Presstek, Inc.Inventors: Lawrence J. Carme, Richard A. Williams, Douglas D. Fuller
