Patent number: 10105907Abstract: A printing system and method of printing an object having a surface of varying height, by a printer configured to print a number of pass images on top of each other in a number of passes, including: deriving from an object image a number of pass images to be printed on top of each other, including: establishing pass pixels of the pass images for which pass pixels a pass pixel height is defined, where a sum of the defined heights of a sequence of pass pixels that corresponds to a respective pixel of the object image equals the height of that pixel of the object image; and printing the pass images on top of each other. An amount of printed material that is printed per printed pass pixel is varied in accordance with the defined pass pixel heights.

Patent number: 10099474Abstract: In a method to check a fixative print head for nozzle failures, a reference mark is printed by the nozzles of a colored ink print head and a test mark is printed via overprinting of the colored ink by the nozzles of the colored ink print head and of a fixative by the nozzles of the fixative print head onto a printing substrate web. The test mark and the reference mark are compared with one another. If the reference mark and the test mark correspond to one another (e.g., at least in part), this indicates that nozzles of the fixative print head are operating incorrectly. If operating incorrectly, the nozzles have, for example, failed entirely or eject the fixative at too great an angular deviation.Type: GrantFiled: February 24, 2017Date of Patent: October 16, 2018Assignee: Océ Holding B.V.Inventors: Ulrich Stoeckle, Philippe Koerner
