Patent number: 8293338Abstract: A method of applying a protective coating over ink printed media in a digital printing engine whereby horizontally discharging ink jet nozzles arranged in a vertical array, discharging a protective coating onto the marked surface of media disposed on a belt in vertical disposition. The coated media is then transported vertically to an adjacent source of ultraviolet radiation for curing the protective coating.Type: GrantFiled: April 15, 2008Date of Patent: October 23, 2012Assignee: Xerox CorporationInventors: Vittorio Castelli, Gregory Joseph Kovacs

Patent number: 8218155Abstract: A method of printing an image on a substrate comprises determining a pile height differential for the image. A clear marking material is added to the image printed on the substrate in response to the determined pile height differential. Adding the clear marking material substantially reduces the pile height differential between two areas of the printed image. The clear marking material may be a clear ink or a clear toner material. The substrate on which the image is printed may comprise a plurality of sheets, a roll or other length of print media. The step of adding clear marking material to the image may include substantially leveling the printed image using the clear marking material. In at least one alternative embodiment, the step of adding clear marking material to the image includes adding at least one patch of clear marking material to the printed image.Type: GrantFiled: April 16, 2008Date of Patent: July 10, 2012Assignee: Xerox CorporationInventor: Gregory Joseph Kovacs

Patent number: 8197024Abstract: An inkjet printer has been developed that reduces the effects of show-through by depositing ink onto a cooled print medium. The inkjet printer includes a printhead and a cooler. The printhead is configured to eject ink onto an ink receiving member as the ink receiving member is transported along a portion of a media path through the inkjet printer. The cooler is positioned proximate the media path to cool the ink receiving member prior to the printhead ejecting ink onto the ink receiving member.Type: GrantFiled: October 29, 2009Date of Patent: June 12, 2012Assignee: Xerox CorporationInventors: Gregory Joseph Kovacs, Bryan James Roof, Michael D. Thompson, Edward B. Caruthers, Lawrence Floyd, Jr., Shawn R. Rowan

Patent number: 8123345Abstract: A system enables ink on an image receiving member to be re-distributed to reduce banding effects in the image. The system includes an ink applicator for applying ink to form an ink image on an image receiving member as it passes by the ink applicator; a plenum chamber for receiving a flow of pressurized fluid from a fluid source, and at least one opening in the plenum chamber to direct the flow of pressurized fluid from the plenum towards the ink image on the image receiving member to re-distribute the ink on the image receiving member.Type: GrantFiled: January 31, 2008Date of Patent: February 28, 2012Assignee: Xerox CorporationInventors: Gregory Joseph Kovacs, Ashish Pattekar, David K. Biegelsen, Lars Erik Swartz, Jennifer L. Belelie, Peter Gordon Odell

Patent number: 7887176Abstract: Methods and devices for forming, such as by printing, high quality, high throughput, ultraviolet curable gel ink images on flexible substrates for packaging applications are disclosed. The methods and devices have excellent image quality and do not require pinning of the ink during color printing or nitrogen inerting during curing.Type: GrantFiled: May 15, 2008Date of Patent: February 15, 2011Assignee: Xerox CorporationInventors: Gregory Joseph Kovacs, Steven E. Ready, Allen W. Denham, Lawrence Floyd, Jr., James Fallon, Jr., Jennifer L. Belelie, Barkev Keoshkerian, Peter Gordon Odell, Christopher A. Wagner
