Abstract: A printing system is disclosed which includes a plurality of rollers configured to support and move a loop-shaped, flexible intermediate transfer member of at least 10 meters in length along a printing system path. The printing system further includes an image forming station configured to form an image on a portion of the intermediate transfer member, and an impression station configured to enable substantial transfer of the deposited image to a substrate. The printing system also includes at least one high-speed motor associated with the plurality of rollers and configured to move the loop-shaped flexible intermediate transfer member at a speed of at least about one meter per second. Moreover, the printing system includes guiding channels configured for exerting a lateral tensioning force on the loop-shaped intermediate transfer member as it is received within the guiding channels and circulates at the speed of at least about one meter per second.

Abstract: A printing process is disclosed which comprises directing droplets of an ink onto an intermediate transfer member to form an ink image, the ink including an organic polymeric resin and a coloring agent in an aqueous carrier, and the transfer member having a hydrophobic outer surface so that each ink droplet in the ink image spreads on impinging upon the intermediate transfer member to form an ink film. The ink is dried while the ink image is being transported by the intermediate transfer member by evaporating the aqueous carrier from the ink image to leave a residue film of resin and coloring agent. The residue film is then transferred to a substrate.

Abstract: A printing system and method are provided. The printing system includes an image forming station for temporarily deposit an image on an intermediate transfer member when the intermediate transfer member in the image forming station is in a first temperature range. The system further includes a drying station configured to increase a temperature of the intermediate transfer member from a first temperature in the first temperature range to a second temperature in a second temperature range, the second temperature being substantially higher than the first temperature. The system further includes an impression station configured to transfer the temporarily deposited image from the intermediate transfer member onto a substrate when the intermediate transfer member in the impression station is in the second temperature range. The system further includes a cooling station for retaining a coolant configured to revert the intermediate transfer member to a temperature in the first temperature.
