  • Patent number: 12214601
    Abstract: A method includes, receiving a first digital image (FDI) to-be printed by a digital printing system (DPS) (10). In a in training phase: for first selected regions (111) in the FDI, a first set of synthetic images (SIs) (112A, 112B, 114A, 114B, 116A, 116B) having a defect caused by a defective part (DP) (99) in the first selected regions, is produced; a neural network (NN) (150) is trained to detect the defect using the first set SIs. In a subsequent detection phase: the NN is applied for identifying, in a second digital image (SDI) (136, 146) acquired from an image produced by the DPS, suspected second regions (135, 145); for each of the second regions, a second set (137, 147) of SIs having DPs that form the defects, is produced; and the DP is identified by comparing, in each of the second regions, between the SDI and the second set SIs.

  • Patent number: 12187027
    Abstract: A system and method for performing quality control in a digital printing system (DPS) is provided. The DPS includes an impression station for transferring an ink image from a surface of an intermediate transfer member to a substrate. The impression station includes an impression cylinder housing one or more grippers operable to grasp and hold a leading edge of the substrate as it passes through the DPS, for conveying the substrate along the impression cylinder during the transfer of the ink image. An imaging device is operable, during advancement of the substrate on the impression cylinder, to capture a digital image including a region of interest (ROI) that is associated with at least a portion of the grippers and at least a portion of the substrate. A controller is configured, based on the digital image, to indicate an error in a position of the substrate relative to the grippers.

  • Patent number: 11833813
    Abstract: A system (10, 110) includes: (i) a flexible intermediate transfer member (ITM) (44, 500, 600), including: a stack of: In (a) a first layer (602), located at an outer surface of the ITM (44, 500, 600), configured to receive ink droplets to form an ink image thereon, and to transfer the ink image to a target substrate (50, 51), and (b) a second layer (603) including a matrix holding particles (622), configured to receive optical radiation (99) passing through the first layer (602), and to heat the ITM (44, 500, 600) by absorbing the optical radiation (99); (ii) an illumination assembly (113), configured to dry the ink droplets by directing the optical radiation (99) to impinge on the particles (622); and (iii) a temperature control assembly (121), configured to control a temperature of the ITM (44, 500, 600) by directing a gas (101) to the ITM (44, 500, 600).

  • Patent number: 9749497
    Abstract: 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.
