Abstract: A printing system for printing on a substrate, comprises a movable intermediate transfer member in the form of a flexible, substantially inextensible, belt guided to follow a closed path, an image forming station for depositing droplets of a liquid ink onto an outer surface of the belt to form an ink image, a drying station for drying the ink image on the belt to leave an ink residue film on the outer surface of the belt, first and second impression stations spaced from one another in the direction of movement of the belt, each impression station comprising an impression cylinder for supporting and transporting the substrate and a pressure cylinder carrying a compressible blanket for urging the belt against the substrate supported on the impression cylinder, and a transport system for transporting the substrate from the first impression station to the second impression station. The pressure cylinder of at least the first impression station is movable between a first position in which the belt is urged towards the impression cylinder to cause the residue film on the outer surface of the belt to be transferred onto the front side of the substrate supported on the impression cylinder, and a second position in which the belt is spaced from the impression cylinder to allow the ink image on the belt to pass through the first impression station and arrive intact at the second impression station for transfer onto the reverse side of the substrate supported on the second impression cylinder.

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.

Some embodiments relate to regulation of a velocity and/or tension and/or length of the ITM. Some embodiments relate to regulation of deposition of ink on the moving ITM. Some embodiments regulate to apparatus configured to alert a user of one or more events related to operation of the ITM. Some embodiments relate to a time-line GUI for visualizing and/or manipulating queued print jobs which may be employed. Some embodiments relate to a reversed augmented reality GUI for visualization and/or control of the printing system. In some embodiments, a display screen is mounted to a printer housing and/or able to control access to moving parts of a printing system.

Abstract: An intermediate transfer member (ITM) for use in a printing system to transport an ink image from an image forming station to an impression station for transfer of the ink image from the ITM onto a printing substrate, wherein the ITM is an endless flexible belt of substantially uniform width which, during use, passes over drive and guide rollers and is guided through at least the image forming station by means of guide channels that receive formations provided on both lateral edges of the belt, wherein the formations on a first edge differ from the formations on the second edge by being configured for providing the elasticity desired to maintain the belt taut when the belt is guided through their respective lateral channels.

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. 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.
Abstract translation: 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。
