Patent number: 6786153Abstract: A printing device, system and method are disclosed for measuring and displaying the amount of wear experienced by printing rolls. A wear detection mechanism is employed in connection with rolls, such as anilox-type rolls that transfer ink to a substrate in forming a printed image. A wear detection mechanism is engraved, etched, or the like into the outer circumferential surface of the roll to provide an indication of the amount of wear experienced by the roll. Portions provided in series at predetermined depths may be correlated with a depletion scale indicia to display the wear condition of a particular roll in a printing system. A depletable wear strip comprising multiple engraved portions which correlate with values upon a depletion scale may be employed.Type: GrantFiled: September 19, 2002Date of Patent: September 7, 2004Assignee: Interflex Laser Engravers, LLCInventors: William Burrow, Gregory Haley

Patent number: 6787583Abstract: An intaglio printing ink comprising a first binder compound selected from the group of water-soluble or water-thinnable acrylate oligomers, and optionally, a second monomeric binder compound selected from the group comprising water-soluble or water-thinnable PEG diacrylate or polyethoxylated polyol triacrylate monomers to adjust the viscosity of the ink composition. To initiate polymerization of the binder compounds upon irradiation by electromagnetic radiation or electron beam radiation a photoinitiator is included. Further optional additives, such as pigments, fillers, photosensitizers, stabilizers emulsifiers and security pigments may be present. The ink shows excellent wipeability and allows precipitation from the wiping solution.Type: GrantFiled: January 10, 2003Date of Patent: September 7, 2004Assignee: SICPA Holding S.A.Inventors: Patrick Veya, Olivier Amrein, Alexia Christinat

Publication number: 20040163555Abstract: A method for manufacturing a ceramic electronic component includes first and second gravure-printing steps in which conductive paste and step-reducing ceramic paste are printed on a composite sheet including a ceramic green sheet. A first print mark is printed before the second gravure-printing step is performed, and the position of the first print mark is determined and compared with a desired position of the first print mark before the second gravure-printing step. Then, the second gravure-printing step is performed such that a second print mark is printed at a suitable position with respect to the position of the first print mark.Type: ApplicationFiled: January 20, 2004Publication date: August 26, 2004Applicant: Murata Manufacturing Co., Ltd.Inventors: Yuichi Ishimoto, Akira Hashimoto

Patent number: 6768561Abstract: In a method for processing signals in an electronic engraving machine for engraving printing forms, in particular printing cylinders used for rotogravure, an engraving control signal is obtained by superimposing engraving data, representing tone values between “white” and “black” which are to be engraved, with a periodic screen signal for generating a gravure screen. The engraving control signal guides the lifting movement of the stylus of an engraving element. As a result of the lifting movement of the stylus, a series of cups arranged in the gravure screen is engraved on the printing form. To compensate an incorrect lifting movement of the stylus (rebound effect, lag effect), the engraving data undergo digital filtering before superposition of the gravure screen.Type: GrantFiled: February 28, 2000Date of Patent: July 27, 2004Assignee: Hell Gravure Systems GmbHInventors: Dieter Fangmeyer, Christian Wiechering, Bernd Lübcke

Patent number: 6761110Abstract: A method by which stacks of printed sheets can be formed and, at the same time, the risk of soiling of the stacked sheets can be reduced to the maximum extent. To this end a printing machine is proposed, in particular a sheet-fed printing machine, into which unprinted and intermediate sheets are alternatively feed, wherein the printing is registered such that the printing occurs only on the unprinted sheets and not on the intermediate sheets. In this way, the intermediate sheets prevent damage to the print on the printed sheets.Type: GrantFiled: September 30, 2002Date of Patent: July 13, 2004Assignee: KBA-Giori S.A.Inventors: Siegfried Alfons Stark, Reinhold Dünninger
