Patent ID: 8096650

Claim:
A method for controlling printing in a solid ink jet printing system, the method comprising: forming a first ink image and a second ink image on a first transfer surface and a second transfer surface, respectively; passing a receiving substrate through a first nip simplex path of a first ink jet printer at a first print speed wherein the first ink jet printer is selectively dedicated to a first side printing; exerting a first pressure on the receiving substrate in the first nip to transfer the first ink image from the first transfer surface to a first side of the receiving substrate; moving the receiving substrate through an inverter path; passing the receiving substrate through a second nip simplex path of a second ink jet printer at a second print speed; exerting a second pressure on the receiving substrate in the second nip to transfer the second ink image from the second transfer surface to a second side of the receiving substrate; wherein the passing the receiving substrate through the first nip is between a first drum and a first roller, the first roller includes a selectively non-oiled transfix roller surface; wherein the passing the receiving substrate through the second nip is between a second drum and a second roller, the second roller includes a selectively oiled transfix roller surface; wherein the first print speed of the first ink jet printer is slower than the second print speed of the second ink jet printer; wherein the transfer of the first ink image and the transfer of the second ink image include a single pass duplexing operation; and, the print speed of the first ink jet printer plus the print speed of the second ink jet printer is faster than a print speed of a multiple pass duplexing operation of the substrate through the first ink jet printer or the second ink jet printer.
