    Abstract: An intermediate transfer member (ITM) (44) of printing system (10), the ITM includes: (a) an outer layer (102) configured to receive droplets (11) of printing fluid for producing an image thereon, and transfer the image to target substrate (50), and (b) a stack (107) of flexible support layers, the stack includes a mesh (109), having a first section impregnated in a first layer (106) having a first elastic modulus in an axis in which a tension force is applied to the ITM (44), and a second section impregnated in a second layer (108), which is placed in contact with the first layer (106) and has in the axis, a second elastic modulus different from the first clastic modulus. In response to applying to the ITM (44) a specified level of the tension force, the stack (107) is configured to retain a predefined elongation of the ITM (44) along the axis.

    Abstract: A system (10) includes a printing assembly (13) and a stacking assembly (59). The printing assembly (13) is configured to print: (i) multiple images on multiple respective substrates (50), and (ii) multiple marks on one or more edges of the multiple respective substrates. The stacking assembly (59) is configured to stack the multiple respective substrates on top of one another to form a stack (88) having a top surface (32) parallel to one or more of the substrates, and sides (21, 31, 41, 51) made from the stacked edges of the substrates. One or more of the marks are visible on a side-view of at least a given side (21) of the sides, and at least a position of the one or more marks in the side view of the given side, is indicative of a problem that occurred while printing one or more of the multiple images.

    Abstract: An indirect printing system is disclosed having an intermediate transfer member (ITM) in the form of an endless belt that circulates during operation to transport ink images from an image forming station. Ink images are deposited on an outer surface of the ITM by one or a plurality of print bars. At an impression station, the ink images are transferred from the outer surface of the ITM onto a printing substrate. In some embodiments, the outer surface of the ITM 20 is maintained within the image forming station at a predetermined distance from the one or each of the print bars 10, 12, 14 and 16 by means of a plurality of support rollers 11, 13, 15, 17 that have a common flat tangential plane and contact the inner surface of the ITM. In some embodiments, the inner surface of the ITM is attracted to the support rollers, the attraction being such that the area of contact between the ITM and each support roller is greater on the downstream side than the upstream side of the support roller, referenced to the direction of movement of the ITM.

    Abstract: Methods for printing using printing systems comprising a flexible intermediate transfer member (ITM) disposed around a plurality of guide rollers at which encoders are installed, and an image-forming station at which ink images are formed by droplet deposition by print bars onto the ITM, can include measuring a local velocity of the ITM under one of the print bars, determining a stretch factor for a portion of the ITM based on a relationship between an estimated stretched length fixed physical distance between print bars, controlling an ink deposition parameter according to the stretch factor so as to compensate for stretching of the reference portion of the ITM.
