Abstract: A digital printing system includes a print head and a processor. The print head is configured to jet droplets of ink. The a processor is further configured to translate a required shade of a color, to be printed at a given location on a substrate by the print head, into a sequence of pulses, the sequence including: (a) up to a predefined maximum number of driving pulses that cause the print head to jet respective droplets, and (b) a tickling pulse, which has a smaller amplitude than the driving pulses and which causes the print head to jet a droplet smaller than the droplets jetted in response to the driving pulses. The processor is additionally configured to apply the sequence of pulses to the print head.

Abstract: 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.

Abstract: A system (10) having a printing position and a non-printing position, the system (10) includes an image forming station (60) and a wiping assembly (200, 400). The image forming station (60) including at least a nozzle plate (61) having one or more nozzles (166, 166a, 166b, 166c), which are configured to apply droplets of a printing fluid onto a surface of one or more substrates (44) for producing one or more images thereon. The wiping assembly (200, 400) is at least partially positioned in a gap (141) between the nozzle plate (61) and the one or more substrates (44), and is configured, while the system (10) is in the printing position, to (i) make physical contact with the nozzle plate (61) and (ii) remove residues of the printing fluid from at least one of the nozzles (166, 166a, 166b, 166c).

Abstract: A manifold is disclosed for introducing gas into a gap between a print head and an intermediate transfer member (ITM) of an indirect inkjet printing system. The manifold has a first gas flow path terminating in a first discharge mouth for delivering a continuous low speed gas stream and a second separate gas flow path terminating in a second discharge mouth, vertically spaced from the first discharge mouth, for intermittently delivering into the gap a high speed gas stream.
