Patent number: 8042933Abstract: In a digital printer the elements involved directly in the print process, which are located on a shuttle assembly are mounted upon a metrological frame which is isolated from the base frame by vibration dampers. Because the elements of the shuttle drive systems, such as a belt drive system having a motor and pulleys, are mounted upon the base frame, the drive and reaction forces from the motor drive systems are led to the base frame while the shuttles assembly is guided by the force-free, vibration free metrological frame. This allows for higher accuracy during printing as the metrological frame serves as a vibration free reference element.Type: GrantFiled: May 8, 2006Date of Patent: October 25, 2011Assignee: Agfa Graphics NVInventors: Arend-Jan Beltman, Albert Brals, Werner Van De Wynckel, Bart Verhoest, Bart Verlinden

Patent number: 8033745Abstract: A digital printer includes a digital printing unit for digital printing an image onto a printing substrate during relative movement between a print head and the printing substrate, and a printing table for holding the printing substrate during the digital printing. The printing table is firmly fixed to the digital printing unit during the digital printing of the image onto the printing substrate and is released from the digital printing unit prior to and after the digital printing of the image onto the printing substrate. The printing table may be moved between a printing position, in which it is firmly fixed to the digital printing unit, and a printing substrate feeding position, in which it supports feeding and removing of the printing substrate from the printing table.Type: GrantFiled: May 30, 2006Date of Patent: October 11, 2011Assignee: Agfa Graphics NVInventors: Bart Verlinden, Bart Verhoest, Werner Van De Wynckel, Albert Brals, Markus Hilpert

Patent number: 7901063Abstract: An ink circulation system for use in an inkjet printing apparatus includes an inkjet printhead, an ink supply path for supplying an ink to the inkjet printhead and an ink return path for returning ink not used for printing from the inkjet printhead. The ink return path is coupled to the ink supply path for replenishing the ink supply path with the ink returned from the printhead. The coupling establishes an ink circulation circuit. The ink circulation circuit can be replenished with fresh ink from a main tank, as ink is withdrawn by the printhead for printing. In the circulation system an active through-flow ink degassing unit is provided to control the dissolved gas level of the ink in the ink circulation system.Type: GrantFiled: December 15, 2005Date of Patent: March 8, 2011Assignee: Agfa Graphics NVInventors: Paul Wouters, Bart Verhoest, Werner Van de Wynckel, Robert Janssens, Erwin Kempeneers

Patent number: 7878625Abstract: A printhead positioning system is provided wherein the shuttle assembly is split up in a printing shuttle, having a high accuracy positioning capability and a utility shuttle needing only a low accuracy positioning system. Due to this split-up the mass of components which have to be positioned accurately is greatly reduced and therefore making it easier to position the lighter load accurately and allowing for use of cheaper drive systems while maintaining the high accuracy in printing.Type: GrantFiled: May 4, 2006Date of Patent: February 1, 2011Assignee: Agfa Graphics NVInventors: Marc van Kalmthout, Arend-Jan Beltman, Albert Brals, Werner Van De Wynckel, Bart Verhoest, Bart Verlinden

Publication number: 20090040249Abstract: An ink circulation system for use in an inkjet printing apparatus includes an inkjet printhead, a supply subtank for containing a supply of ink for the inkjet printhead and a return subtank for containing a surplus of ink not used by the inkjet printhead. The supply subtank is coupled with the return subtank and with the inkjet printhead via a first fluid path. A second fluid path couples the return subtank with the supply subtank for circulating the ink from the return subtank back to the supply subtank. This way a closed ink circulation path is realized. The ink flow from the supply subtank to the inkjet printhead and to the return subtank is controlled by means of a pressure difference between the ink in the supply subtank and the ink in the return subtank. A back pressure at the nozzle of the inkjet printhead is established via active pressure control means.Type: ApplicationFiled: December 15, 2005Publication date: February 12, 2009Inventors: Paul Wouters, Bart Verhoest, Werner Van de Wynckel, Robert Janssens, Erwin Kempeneers
