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: A method of printing includes, applying to an intermediate transfer member (ITM) (44), one or more fluids that include at least a printing fluid for forming an image on the ITM (44). At least part of the image is transferred from the ITM (44) to a target substrate (50). Residues of the one or more fluids that were not transferred to the target substrate (50) and remained on the ITM (44), are transferred from the ITM (44) to one or more rotatable elements (112), and the residues are removed from the one or more rotatable elements (112).
