Patent number: 7977031Abstract: A method of processing an on-press developable lithographic printing plate involves the removal of overcoat by brushing or rubbing while in contact with water or an aqueous solution after imagewise exposure and before on-press development. The plate comprises a substrate, an on-press ink and/or fountain solution developable photosensitive layer, and a water soluble or dispersible overcoat. Preferably, the overcoat is incapable of being completely removed with ink and/or fountain solution on a lithographic press during roll up. Such a method allows the use of more durable overcoat for on-press developable plate.Type: GrantFiled: March 26, 2008Date of Patent: July 12, 2011Inventor: Gary Ganghui Teng

Publication number: 20110155008Abstract: The present invention relates to a double-sided imprint apparatus capable of simultaneously imprinting both surfaces of a transfer printing target such as a doughnut-shaped, circular disc substrate. The double-sided imprint apparatus includes: an upper surface stamper device that is supported by an elevation mechanism; a lower surface stamper device that is fastened to a transport table mounted on a guide rail; and a transfer printing target separator, in which the transport table moves back and forth along the guide rail with the aid of a transport drive mechanism, thereby allowing the lower surface stamper device and the transfer printing target separator to alternately move to a position facing the upper surface stamper device, which is positioned at the center of the upper surface stamper device.Type: ApplicationFiled: December 22, 2010Publication date: June 30, 2011Inventors: Noritake SHIZAWA, Kyoichi Mori, Takashi Tarumitsu, Toshimitsu Shiraishi

Patent number: 7966934Abstract: A method of processing an overcoat-free on-press developable lithographic printing plate with ink and/or fountain solution is described. The plate comprises on a substrate a photosensitive layer which is either capable of hardening (negative-working) or solubilization (positive-working) upon exposure to a laser, the non-hardened or solubilized areas of the photosensitive layer being soluble or dispersible in ink and/or fountain solution. The plate is exposed with a laser, heated to an elevated temperature, and then developed with ink and/or fountain solution on a lithographic press. The laser exposed plate is preferably heated by passing through a heating device or while mounted on a lithographic press before on-press development.Type: GrantFiled: October 2, 2008Date of Patent: June 28, 2011Inventor: Gary Ganghui Teng

Publication number: 20110139027Abstract: Improved low k1 lithographic imaging is disclosed by optimizing or improving an illumination polarization condition. The polarization condition may be a pre-defined spatially varying polarization, or a spatially customized local polarization of bright illumination points based on tracking a value of a desired lithographic response. Several non-traditional polarization conditions, e.g., TM/TE polarization (with or without a central TM region), diagonal polarization, and Y+X polarization (typically for dark field illumination) are disclosed, that offer substantial imaging advantages for specific lithographic problems, especially at low k1 values. The initial polarization definition may be limited to specific fixed polarization angles.Type: ApplicationFiled: November 22, 2010Publication date: June 16, 2011Applicant: ASML NETHERLANDS B.V.Inventor: Steven George HANSEN

Publication number: 20110094403Abstract: The present invention relates to a silicone rubber like material and a printing device including a stamp layer (100;201) comprising such a material. The material is suitable for use in soft lithography as it enables stable features having mensions in the nanometer range to be obtained on a substrate, and also allows for the accommodation onto rough and non-flat substrate surfaces. The invention also relates to methods for manufacturing the silicone rubber like material and stamp layer (100;201) and use thereof in lithographic processes.Type: ApplicationFiled: May 29, 2009Publication date: April 28, 2011Applicant: Koninklijke Philips Electronics N.V.Inventor: Marcus Antonius Verschuuren

Patent number: 7913620Abstract: A method of processing an on-press developable lithographic printing plate involving the removal of overcoat after imagewise exposure and before on-press development is described. The plate comprises a substrate, an on-press ink and/or fountain solution developable photosensitive layer, and an overcoat. The laser imaged plate is stripped off the overcoat, and then under a white room light mounted on press and developed with ink and/or fountain solution. Here the plate is capable of hardening upon exposure to a laser, has limited white light stability before the removal of the overcoat, and has significantly improved white light stability after the removal of the overcoat.Type: GrantFiled: March 3, 2008Date of Patent: March 29, 2011Inventor: Gary Ganghui Teng
