    Abstract: A method includes, receiving a first digital image (FDI) to-be printed by a digital printing system (DPS) (10). In a 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.

    Abstract: A system (10) includes an intermediate transfer member (ITM) (44) and a substrate conveyor (80). The ITM (44) is configured to receive droplets of one or more printing fluids so as to form an image thereon, and to transfer the image to a target substrate (50). The substrate conveyor (80) is configured to grip and move the target substrate (50) to and from the ITM (44) for transferal of the image, the substrate conveyor (80) includes one or more rotatable elements (110, 200), which are configured to provide mechanical support to the target substrate (50), such that, when the target substrate (50) moves over the one or more rotatable elements (110, 200), at least one of the rotatable elements (110, 200) is configured to rotate in response to a physical contact with the target substrate (50).

    Abstract: Printing apparatus (20) includes a continuous blanket (24) and a set of motorized rollers (31), which advance the blanket at a constant speed through an image area. One or more print bars (38) eject droplets of ink at respective locations onto the blanket in the image area. One or more monitoring rollers (42), in proximity to the locations of the print bars, contact the blanket so as to be rotated by advancement of the blanket. Each monitoring roller includes an encoder (44), which outputs a signal indicative of a rotation angle of the monitoring roller. A control unit (40) collects, during a calibration phase, the signal from the encoders over multiple rotations of the monitoring rollers and computes runout correction factors. During an operational phase, the control unit synchronizes ejection of the droplets from the print bars using the computed runout correction factors.

    Abstract: An intermediate transfer member (ITM) for use in a printing system. The ITM includes an endless flexible belt formed of an elongate belt having a longitudinal axis. Attached to lateral edges of the endless flexible belt along the longitudinal axis are a first elongate strip and a second elongate strip, each of the elongate strips including lateral formations on outward facing lateral ends thereof which are distal to the lateral edges of the belt. At least one of the first and second elongate strips includes a first longitudinal portion having a first elasticity, and a second longitudinal portion having a second elasticity, such that the second elasticity is greater than the first elasticity. The first portion is attached to the lateral edges of the flexible belt and the second portion extends between the first portion and the lateral formations.

    Abstract: A heat-curable tape, a kit, and a method for connecting ends of an elongate belt to form an intermediate transfer members suitable for use with indirect printing systems. The kit includes an elongate belt and the heat-curable tape. The kit can include a crimping pin. The method includes using the heat curable tape to join ends of the elongate belt at a seam. A heater is used, in a printing system, for heat-curing the heat-curable tape onto the free ends of the elongate belt so as to form the intermediate transfer member.
