Abstract: An apparatus and method for ink-jet printing including an intermediate transfer medium, a transfer medium, and an ink-jet print head to jet ink toward the intermediate transfer medium, to transfer an ink image from the intermediate transfer medium to media with an optimum image transfer and optical density. The optimum image transfer and optical density is accomplished by generating uniform pressure across a nip generated by the intermediate transfer medium and the transfer medium, and control of a release coating thickness resident on the intermediate transfer medium and a time delay between a jetting of ink toward the intermediate transfer medium and transfer of jetted ink resident on a surface of the intermediate transfer medium to the media.
