Patent number: 6989220Abstract: Laser imageable flexographic printing elements, including printing plates and printing sleeves and methods of making the laser imageable flexographic printing elements using a collapsible cross-linkable material comprising a curable elastomer, a material that absorbs laser radiation at a selected wavelength, and microspheres are disclosed. A laser is used to collapse and melt the collapsible cross-linkable material to form a relief image on the printing element. The printing element is thereafter cured by face exposure to crosslink and cure the formed relief image. The invention addresses a market need for eliminating chemical processing of printing elements, thus going from printing element to press much more quickly and using an environmentally friendly process.Type: GrantFiled: January 30, 2004Date of Patent: January 24, 2006Assignee: MacDermid Printing Solutions, LLCInventor: Rustom Sam Kanga

Patent number: 6916596Abstract: Laser-imageable flexographic printing plates and a method of making same are disclosed. A thin polymeric film doped with a UV absorber is laminated to a photopolymer layer. The film is ablated from the photopolymer using a laser operating at a selected wavelength to create an in situ negative. The resulting negative can be subjected to typical UV flood exposure and development.Type: GrantFiled: July 3, 2001Date of Patent: July 12, 2005Inventors: Michael Wen-Chein Yang, Rustom Sam Kanga, Alvin Varnard Randall

Patent number: 6806018Abstract: A laser imageable flexographic printing plate and a method of making the laser imageable flexographic printing plate using a collapsible UV cross-linkable material comprising a UV-curable elastomer, an IR dye, and microspheres is disclosed. The collapsible UV cross-linkable material is mixed together and then extruded to form a printing plate. An IR laser is used to collapse and melt the collapsible UV cross-linkable material to form a relief image on the printing plate. The printing plate is thereafter UV cured by face exposure to crosslink and cure the formed relief image. The invention addresses a market need for eliminating chemical processing of printing plates, thus going from plate to press much more quickly. The printing plate may also contain a thin layer of a high-density non-collapsible UV-curable elastomer between the collapsible layer and the cover sheet of the plate which acts as the print surface in the final plate.Type: GrantFiled: March 25, 2002Date of Patent: October 19, 2004Assignee: MacDermid Graphic Arts, Inc.Inventors: Rustom Sam Kanga, Daniel Rosen

Patent number: 6413699Abstract: The present invention provides a method for producing direct-imaged flexographic printing elements such that both the front and back exposure times are economically efficient for the manufacturer. In one embodiment, the method comprises providing at least one solid photocurable element. The solid photocurable element comprises a solid photocurable material comprising an oxygen scavenger, a support layer having an actinic radiation absorbing compound integrated uniformly throughout such that it absorbs at least some actinic radiation during exposure, and a photoablative mask layer. The methods of the invention involve creating a floor in the solid photocurable material by back exposure through the support layer having the actinic radiation absorbing compound, transferring a negative image directly onto the solid photocurable material by photoablating the photoablatable mask layer, followed by front exposure effective to cure the solid photocurable material.Type: GrantFiled: October 11, 1999Date of Patent: July 2, 2002Assignee: MacDermid Graphic Arts, Inc.Inventor: Rustom Sam Kanga
