Abstract: A flexible belt is disclosed for use in a printing system. The belt comprises an endless strip which, in use, travels along a continuous path. Formations are provided along the sides of the strip which are capable of engaging with lateral tracks to place the belt under lateral tension, the lateral tracks further serving to constrain the belt to follow the continuous path.

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: 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.

Abstract: A printing system is described that has an intermediate transfer member in the form of a seamed endless belt for transporting an ink image from an image forming station, at which an ink image is deposited on the intermediate transfer member, to an impression station, where the ink image is transferred onto a printing substrate. The belt has along its edges formations of a greater thickness than the belt. The formations are received in channels to guide the belt and maintain the belt under lateral tension. Two drive members are provided, each located within a respective one of the channels. The two drive members are connected for movement in synchronism with one another and each has a respective laterally projecting gripper shaped for form locking engagement with the formations on a leading end of a strip from which the intermediate transfer member is to be formed. Rotation of the drive members during installation of a new intermediate transfer member serves to thread the strip through the printing system by pulling the strip from its leading end.

Abstract: An intermediate transfer member (ITM) for use in a printing system to transport an ink image from an image forming station to an impression station for transfer of the ink image from the ITM onto a printing substrate, wherein the ITM is an endless flexible belt of substantially uniform width which, during use, passes over drive and guide rollers and is guided through at least the image forming station by means of guide channels that receive formations provided on both lateral edges of the belt, wherein the formations on a first edge differ from the formations on the second edge by being configured for providing the elasticity desired to maintain the belt taut when the belt is guided through their respective lateral channels.
