摘要： There is provided a method for treating a hydrophobic release layer of an intermediate transfer member for use in a printing process in which a negatively charged aqueous inkjet ink including a polymeric resin and a colorant is jetted onto said layer, the claimed method comprising contacting the release layer, prior to jetting the ink, with an aqueous solution or dispersion of a positively charged polymeric chemical agent reducing the tendency of a jetted ink droplet to bead up on the intermediate transfer member. Other embodiments, such as hydrophobic release layers having such chemical agents disposed thereupon and printed ink images comprising the same, are also described.

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： Some embodiments relate to printing system is described that has an intermediate transfer member (ITM) in the form of a seamed endless belt for transporting an ink image from an image forming station, at which an ink image is deposited on ITM, to an impression station, where the ink image is transferred onto a printing substrate. Two drive members are provided for movement in synchronism with one another. Rotation of the drive members during installation of a new ITM serves to thread the strip through the printing system by pulling the strip from its leading end. Alternatively or additionally, indirect printing system comprising the ITM and an image forming station at which droplets of ink are applied to the ITM to form ink images thereon is disclosed. One or more blowing mechanisms (e.g. associated with the image forming station) are disclosed herein.

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.

摘要： 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.

摘要： Aqueous inkjet ink formulations comprising a solvent including water and a co-solvent, a water soluble or water dispersible polymeric resin and a colorant, and a method for facilitating the use of such an aqueous inkjet ink in an indirect printing system in which the ink is jetted onto a hydrophobic release layer of an intermediate transfer member before having the solvent removed therefrom and being transferred to a substrate, wherein prior to the jetting of the ink the release layer is brought into contact with an aqueous solution of a positively charged polymeric chemical agent. Other aspects are also described.

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.
