Abstract: A flexible belt is disclosed for use in a printing system. The belt comprises an endless strip which, in use, travels along a continuous path. Formations are provided along the sides of the strip which are capable of engaging with lateral tracks to place the belt under lateral tension, the lateral tracks further serving to constrain the belt to follow the continuous path.

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: 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.
