摘要： 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. The chemical compositions of the ink and of the surface of the intermediate transfer member are selected such that attractive intermolecular forces between molecules in the outer skin of each droplet and on the surface of the intermediate transfer member counteract the tendency of the ink film produced by each droplet to bead under the action of the surface tension of the aqueous carrier, without causing each droplet to spread by wetting the surface of the intermediate transfer member.

摘要翻译：公开了一种印刷方法，其包括将油墨的液滴引导到中间转印部件上以形成油墨图像，所述油墨在水性载体中包含有机聚合物树脂和着色剂，并且所述转印部件具有疏水性外表面，使得墨水图像中的每个墨滴在撞击中间转印部件时展开以形成墨膜。当油墨图像由中间转印部件传送时，通过从油墨图像中蒸发水性载体而使油墨干燥，留下树脂和着色剂的残留物膜。然后将残余膜转移到基底。选择墨水和中间转印部件的表面的化学组成，使得每个液滴的外表皮中的分子与中间转印部件的表面之间的有吸引力的分子间力抵消了由每个液滴产生的油墨膜的趋势在水性载体的表面张力的作用下液滴到珠粒，而不会通过润湿中间转印部件的表面而使每个液滴扩散。

摘要： 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.

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.
