An indirect printing system comprises an intermediate transfer member (ITM) 20 in the form of an endless belt that circulates continuously to transport ink images from an image forming station, where the ink images are deposited on an outer surface of the ITM 20 by a plurality of print bars 10, 12, 14, 16, to an impression station where the ink images are transferred from the outer surface of the ITM 20 onto a printing substrate; the outer surface of the ITM 20 is maintained at a predetermined distance from the print bars 10, 12, 14, 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; the inner surface of the ITM 20 and the outer surface of each support roller 11, 13, 15, 17 are formed of materials that, tackily adhere to one another. Adhesion between the outer surface of each of the support rollers 11, 13, 15, 17 and the inner surface of the ITM 20 prevents the ITM 20 from separating from the support rollers 11, 13, 15, 17. Preferably the inner material of the ITM 20 is a soft conformable material or a tacky silicone based material. |
