  • Patent number: 6196675
    Abstract: An apparatus and related method for improved image fusing in an ink jet printing system are provided. An ink image is transferred to a final receiving substrate by passing the substrate through a transfer nip. The substrate and ink image are then passed through a fusing nip that fuses the ink image into the final receiving substrate. Utilizing separate image transfer and image fusing operations allows improved image fusing and faster print speeds. The secondary fusing operation enables the image transfer process to use reduced pressures, whereby the load on the drum and transfer roller is reduced. Additionally, the secondary fusing operation may be utilized to apply a supplemental coating to the transferred image.

  • Patent number: 6113231
    Abstract: An apparatus and related method for high speed offset ink jet printing are provided. Multiple print head modules form a full width ink image by ejecting ink drops onto an intermediate transfer surface on a rotating drum. One or more complete images are formed on the intermediate transfer surface in less than one revolution of the drum. The images are then transferred to a final receiving medium while additional images are simultaneously formed on the intermediate transfer surface as the drum continues to rotate. Two or more color component images may be overlayed to form a complete color image in less than one revolution of the drum. Additionally, the simultaneous imaging and image transfer allow the apparatus and method to print images having a length greater than the circumference of the drum.
