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: Embodiments of the present invention relate to control apparatus and methods of a printing system, for example, comprising an intermediate transfer member (ITM) and to user-related features of a printing system. Some embodiments relate to regulation of a velocity and/or tension and/or length of the ITM. Some embodiments relate to regulation of deposition of ink on the moving ITM. Some embodiments regulate to apparatus configured to alert a user of one or more events related to operation of the ITM. Some embodiments relate to a time-line GUI for visualizing and/or manipulating queued print jobs which may be employed. Some embodiments relate to a reversed augmented reality GUI for visualization and/or control of the printing system. In some embodiments, a display screen is mounted to a printer housing and/or able to control access to moving parts of a printing system.

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: Embodiments of the invention relate to a method of indirect printing with an aqueous ink. In some embodiments, an intermediate transfer member (ITM) comprising a silicone-based release layer surface is employed. For example, the release layer surface satisfies at least one of the following properties: (i) a receding contact angle of a drop of distilled water deposited on the silicone-based release layer surface is at most 60°; and (ii) a 10-second dynamic contact angle (DCA) of a drop of distilled water deposited on the silicone-based release layer surface is at most 108°. Related apparatus, systems and treatment formulations are disclosed herein.
