Patent number: 7534544Abstract: In a method of using a donor element in a radiation-induced thermal transfer process, an assemblage is provided that includes a donor element and a receiver element, wherein the donor element has a support layer and a transfer layer having one side adjacent the support layer and the other side adjacent the receiver element. After image-wise exposing the assemblage to radiation whereby a portion of the transfer layer is transferred to the receiver element, relative movement between the support layer and the receiver element is provided before separating the donor element from the receiver element. Advantages include improved edge straightness, image width predictability, improved thermal mass transfer, and improved color filters.Type: GrantFiled: October 19, 2007Date of Patent: May 19, 2009Assignee: E.I. du Pont de Nemours and CompanyInventors: Frank S. Principe, Edmund Francis Schieffer, Jr., Ian Michael Garben, Paul Holt

Patent number: 7531285Abstract: A method of creating a digital mask in situ for use in a process of making digital flexographic printing elements. The digital mask is created by laminating the negative image that is the by-product of a thermal proofer to a photosensitive printing plate. Thereafter, the photosensitive printing element can be imaged, exposed, and developed in the usual manner.Type: GrantFiled: January 17, 2006Date of Patent: May 12, 2009Inventor: David Recchia

Patent number: 7504190Abstract: The present invention relates to a method for fluorescent image formation which can form a highly scratch-resistant fluorescent full-color image using a colorless fluorescent agent and can freely regulate the tone of color mixture of a combination of two or more fluorescent colors in order to impart, to articles, a higher level of forgery preventive function than a prior art technique and a print having a high level of forgery preventive function. The invention characterized in that fluorescent inks are provided that are substantially colorless upon visible light irradiation and contain organic fluorescent agents which, upon ultraviolet light irradiation, emit fluorescences in a visible region, and that two or more fluorescent inks, which emit fluorescences having mutually different color tones, are deposited on a printing face in its image formation region according to information on an image to be printed in a dot matrix manner so that dots of one color do not overlap with dots of another color.Type: GrantFiled: May 11, 2005Date of Patent: March 17, 2009Assignee: Dai Nippon Printing Co., Ltd.Inventors: Satoshi Narita, Koji Eto
