Patent number: 6785425Abstract: A Simple Inter Color Lossless Image Coder (SICLIC) for the compression of colored images is provided. The color image is treated as several interlaced gray level images that correspond to respective distinct color planes. The compression scenario utilizes three main steps, such as selection of the predictor, context forming with bias cancellation and coding. SICLIC implements predictors, context forming and encoder techniques that exploit the intra- and inter-color plane correlations in an effective and relatively computationally inexpensive manner. The predictor is selected on the basis of the right selection of the contribution of each color plane between the intra- and inter-plane predictors obtained as a weight average of contribution from different color planes. SICLIC processes the image in two modes—regular mode and run mode. A special care is taken to ensure a proper treatment of joint runs, which occur simultaneously in all color planes.Type: GrantFiled: March 24, 2000Date of Patent: August 31, 2004Assignees: Ramot At Tel-Aviv University Ltd., Creo Il.

Patent number: 6779455Abstract: The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.Type: GrantFiled: March 27, 2003Date of Patent: August 24, 2004Assignee: Creo Il Ltd.Inventors: Murray Figov, Anna Sigalov

Patent number: 6654147Abstract: The present invention presents method and apparatus for anti-aliasing elements in pages containing variable information, to be printed by a digital printer. Each page element is pre-rasterized to a resolution higher by a given factor than the output resolution, and the pixels that belong to non-printable areas are denoted ‘Background’. During the anti-aliasing (averaging) process, each new pixel gets an attribute value, dependent on the higher resolution pixels that contributed to the new pixel: Background—if all contributing pixels were denoted ‘Background’. Opaque—if all contributing pixels were denote ‘Non-Background’. Semi-Background—if the contributing pixels were partly ‘Background’ and partly ‘Non-Backgroun’.Type: GrantFiled: July 6, 1999Date of Patent: November 25, 2003Assignee: Creo IL Ltd.Inventor: Ran Lasco Ramot

Patent number: 6640713Abstract: An improved offset printing press has a single plate blanket image (PBI) cylinder for holding an image formed on a thin film printing plate affixed thereto. The plate may be from 0.5 to 25 microns thick and has a thin layer of ink repelling material coated thereon. The plate is imaged, after being affixed to the PBI cylinder, by ablating selective portions of the ink repelling coating. The PBI cylinder is constructed to hold the printing plate by vacuum techniques, and apparatus to load and unload the plate is associated with the PBI cylinder. Because of the thinness of the printing plate, the PBI cylinder is a compliant surface, capable of printing on an inelastic media covered impression cylinder. In addition, unique inking apparatus is provided to transfer ink to the imaged printing plate. Variations of the press include a four color press utilizing a single PBI cylinder.Type: GrantFiled: November 6, 2002Date of Patent: November 4, 2003Assignee: Creo IL. LTDInventor: Robert M. Landsman

Publication number: 20030174235Abstract: A method and apparatus for composing uniform lighting and correcting for any remaining lighting non-uniformity. The method involves capturing a reference image utilizing a background sheet of uniformly reflective material. The reference image is processed and an exaggerated version of the reference image highlighting the hot and cold regions is displayed. The user modifies the lighting to compose the flattest lighting possible. A lighting calibration file is saved comprising a smoothed approximation of the light intensity of each pixel and the average of the pixels. The actual image is corrected for the remaining non-uniform lighting by utilizing the lighting calibration file.Type: ApplicationFiled: December 18, 2002Publication date: September 18, 2003Applicant: Creo IL.
