Patent number: 10562318Abstract: Embodiments of the invention relate to techniques whereby sufficient compensation is provided to counteract the deleterious effects of a malfunctioning nozzle (i.e. which might create a white streak within the printed ink image) in a manner that is faithful to/harmonious with the underlying AM or FM screening. In this manner, it is possible to minimize the negative impact a failed or malfunctioning nozzle has upon the printed ink image.Type: GrantFiled: November 5, 2018Date of Patent: February 18, 2020Assignee: LANDA CORPORATION LTD.Inventors: Alon Siman-Tov, Shahar Klinger, Mattetyahu Litvak, David Tal

Patent number: 9749497Abstract: There is provided an ink-deposition device suitable for depositing ink on a target surface and a printing system comprising the same. In operation in a printing system, the ink-deposition device can convert digital images into ink images on the target surface using pixel-masks and methods as disclosed herein. Advantageously, the ink-deposition device, the printing system comprising it and the methods of using the same can reduce or prevent the occurrence of some undesired ink-formations typically governed by the respective physical and/or chemical properties of the surface and ink being used or mitigate their effect on print quality. Application of the pixel-image mask yields a binary image that exhibits pixel-clusters with stochastically distributed centroids.Type: GrantFiled: January 22, 2015Date of Patent: August 29, 2017Assignee: LANDA CORPORATION LTD.Inventors: Mattetyahu Litvak, Shahar Klinger, Alon Siman Tov, Avraham Guttman
