1. An indirect printing system comprising:
(a) an intermediate transfer member (ITM) having a release layer having an ink reception surface;
(b) a plurality of printing heads configured to apply an ink image to the ink reception surface of the ITM,
wherein:
I. the release layer is formed of a silicone material;
II. the ink reception surface of the release layer is adapted to satisfy at least one of the following structural properties:
(i) a receding contact angle of a droplet of distilled water on said ink reception surface is at most 60°; and
(ii) for a droplet of distilled water deposited on said ink reception surface, a 10 second dynamic contact angle (DCA) is at most 108°; and
III. the release layer has at least one of the following structural properties:
(1) said silicone material consisting essentially of a silicone, or containing, by weight, at least 95% of said silicone; and
(2) functional groups make up at most 5% by weight, of said silicone material.
