Patent number: 8919252Abstract: An Ink-based digital printing system comprises an external fluid applicator for applying multi-component, multi-functional fountain solution to a surface of an imaging plate. The plate is image wise exposed using a high power laser to remove primary components of the fountain solution from select regions of the plate according to digital image data, leaving a layer of the secondary components at said select regions. The plate is then inked with ink useful in printing. The ink adheres to the select regions from which the primary components have been removed to form an ink image. The ink image is transferred at an image transfer step wherein the secondary components enable efficient transfer of the ink to a medium with reduced image quality defects. The multi-component fountain solution comprises primary components that reject or repel ink, and secondary components that function as a release agent.Type: GrantFiled: August 31, 2012Date of Patent: December 30, 2014Assignee: Xerox CorporationInventors: Jack Lestrange, Santokh S. Badesha, Mandakini Kanungo, David J. Gervasi, Maryna Ornatska, Matthew M. Kelly

Patent number: 8005390Abstract: A method creates a printing image charge on a photoreceptor printing region of a photoreceptor within a printing apparatus and, simultaneously with the creating of the printing image charge, charges source patches on the photoreceptor outside the photoreceptor printing region. The method then transfers developer material from a donor roll to the photoreceptor. The source patches cause developer material to be removed from areas of the donor roll outside a donor roll printing region to create developer material-depleted regions. The method then reloads the donor roll with developer material using a magnetic brush and evaluates a reload function of the donor roll by characteristics of developer material on target patches with developer material in areas of the non-printing region of the photoreceptor adjacent the target patches. The method then alters the printing image charge to maintain the reload function within a predetermined range.Type: GrantFiled: October 15, 2008Date of Patent: August 23, 2011Assignee: Xerox CorporationInventors: Palghat S. Ramesh, Joseph Sheflin, Jack LeStrange, Peter Paul, Aaron M. Burry

Patent number: 7911652Abstract: A test target is written in a non image zone at set time intervals. The test target is sensed. At least one of frequency, amplitude and phase of banding, which is inherent in a printing device, is determined based on the sensed test target. At least one banding compensation parameter based at least on one of the determined frequency, amplitude and phase of banding is determined. Characteristics of producing an image based on the determined banding compensation parameter are adjusted to compensate the banding inherent in the printing device.Type: GrantFiled: September 8, 2005Date of Patent: March 22, 2011Assignee: Xerox CorporationInventors: Nancy B.
