    Abstract: A jacket-securing arrangement is disclosed for mounting in a cylinder, which cylinder (220) has an outer surface and at least one recess (320) in the outer surface for receiving an inwardly turned edge of a replaceable jacket (225) overlying at least part of the outer surface of the cylinder. The jacket-securing arrangement is mountable within the recess so as not to project beyond the outer surface of the cylinder when the jacket is secured thereto, and includes a clamping lever pivotable about a shaft located within the recess between a clamping position in which the edge of the replaceable jacket is clamped between the lever and a side wall of the recess and a release position in which the lever is spaced from the side wall of the recess. A magnet is provided to retain the lever in the clamping position. The clamping lever is formed of two or more members assembled around the shaft and defining between them a bearing surface engaging an outer surface of the shaft. The shaft may be a gripper shaft including a plurality of grippers for securing a printing substrate sheet to the outer surface of a substrate transport cylinder of a printing system, the jacket-securing arrangement being disposed between grippers.

    Abstract: A digital printing system includes an intermediate transfer member (ITM), to receive a printing fluid to form an image, a continuous target substrate having opposing first surface and second surface, a light source to illuminate the first surface, and an image sensor to image at least a portion of the light transmitted through the target substrate to the second surface, and a processor. The target substrate configured to engage with the ITM at an engagement point for receiving the image from the ITM, and at the engagement point, the ITM is configured to move at a first velocity and the target substrate is configured to move at a second velocity. The processor is configured to produce a digital image based on the electrical signals, and to estimate, based on the digital image, at least a distortion in the image.

    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: A printing system for printing on a substrate, comprises a movable intermediate transfer member in the form of a flexible, substantially inextensible, belt guided to follow a closed path, an image forming station for depositing droplets of a liquid ink onto an outer surface of the belt to form an ink image, a drying station for drying the ink image on the belt to leave an ink residue film on the outer surface of the belt, first and second impression stations spaced from one another in the direction of movement of the belt, each impression station comprising an impression cylinder for supporting and transporting the substrate and a pressure cylinder carrying a compressible blanket for urging the belt against the substrate supported on the impression cylinder, and a transport system for transporting the substrate from the first impression station to the second impression station. The pressure cylinder of at least the first impression station is movable between a first position in which the belt is urged towards the impression cylinder to cause the residue film on the outer surface of the belt to be transferred onto the front side of the substrate supported on the impression cylinder, and a second position in which the belt is spaced from the impression cylinder to allow the ink image on the belt to pass through the first impression station and arrive intact at the second impression station for transfer onto the reverse side of the substrate supported on the second impression cylinder.
