  • Publication number: 20210394531
    Abstract: 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.

  • Patent number: 11203199
    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.
