摘要： A digital printing system (10) includes a flexible intermediate transfer member (ITM) (44) and a dancer assembly (100). The ITM (44) is configured to receive ink droplets from an ink supply system to form an image thereon, and to transfer the image to a target substrate (50). The dancer assembly (100) includes a fluid chamber (103) and a rotatable element (111) fitted in the fluid chamber (103), the fluid chamber (103) includes an inlet (107) configured to receive pressurized fluid (130) into the fluid chamber (103), and the pressurized fluid (130) causes the rotatable element (111) to move relative to the fluid chamber (103) and to apply tension to the ITM (44) while being rotated by the ITM (44).

摘要： 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.

摘要： A friction reduction system for reducing friction of an intermediate transfer member (ITM) of a printing system, while the ITM is guided along the printing system by a guiding arrangement. The friction reduction system includes a fluid reservoir mounted within the printing system, a fluid depositing arrangement disposed along the ITM, and a control mechanism, adapted to control depositing of fluid, from the fluid depositing arrangement onto the guiding arrangement or onto at least a portion of the ITM. Depositing of the fluid reduces friction between the ITM and the guiding arrangement.

摘要： A method of printing includes, applying to an intermediate transfer member (ITM) (44), one or more fluids that include at least a printing fluid for forming an image on the ITM (44). At least part of the image is transferred from the ITM (44) to a target substrate (50). Residues of the one or more fluids that were not transferred to the target substrate (50) and remained on the ITM (44), are transferred from the ITM (44) to one or more rotatable elements (112), and the residues are removed from the one or more rotatable elements (112).

摘要： Some embodiments relate to printing system is described that has an intermediate transfer member (ITM) 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 ITM, to an impression station, where the ink image is transferred onto a printing substrate. Two drive members are provided for movement in synchronism with one another. Rotation of the drive members during installation of a new ITM serves to thread the strip through the printing system by pulling the strip from its leading end. Alternatively or additionally, indirect printing system comprising the ITM and an image forming station at which droplets of ink are applied to the ITM to form ink images thereon is disclosed. One or more blowing mechanisms (e.g. associated with the image forming station) are disclosed herein.
