  • Patent number: 10864716
    Abstract: A dampening fluid recycling system may include a print station having an imaging member with a reimageable surface, a dampening fluid deposition subsystem for applying a layer of dampening fluid onto the reimageable surface, and a dampening fluid recovery subsystem configured to remove excess dampening fluid vapor that does not condense over the reimageable surface. The dampening fluid deposition subsystem may include a dampening fluid supply chamber, a dampening fluid supply channel, and a dampening fluid supply channel outlet. The dampening fluid supply chamber may include an inlet tube and a tube body that may be a split tube. The dampening fluid supply channel may attach to the split tube and descend towards the imaging member to deliver fluid vapor from both parts of the first split tube onto the reimageable surface of the imaging member.

  • Patent number: 10814611
    Abstract: A dampening fluid deposition system includes a vapor generator adjacent an air supply channel and in fluid communication with a dampening fluid supply to produce dampening fluid vapor. The vapor generator includes a vapor channel having an interior in communication with air confined within the air supply channel. The vapor generator may include a liquid reservoir receiving dampening fluid from the dampening fluid supply and a heater that heats the received dampening fluid into dampening fluid vapor. The liquid reservoir may include a wick that stores dampening fluid and releases dampening fluid vapor into the vapor channel and a heat conductive tub that holds the wick and dampening fluid. The passive dampening fluid deposition system mixes the dampening fluid vapor with the confined air to form an air/vapor mix that is condensed as a layer of dampening fluid onto the reimageable surface of an imaging member.

  • Patent number: 10069996
    Abstract: In an example embodiment, an image processing system can be implemented, which includes a printing surface and a prism that splits light from an input light source into two parallel light beams indicative of a signal image. Two or more DMDs (Digital Micromirror Devices) can be utilized, wherein the two parallel light beams are directed to the DMDs for image processing, such that as the two parallel light beams are reflected out onto the printing surface, the two parallel light beams are recombined into a single image, thereby enabling heat dissipation while “stitching” said output of said at least two digital micromirror devices to a usable video path.
