Passive vapor deposition system and method
10562290 · 2020-02-18 · ·

A dampening fluid deposition system includes a vapor generator adjacent the 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.

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.

Charged particle generation, filtration, and delivery for digital offset printing applications

Ink-based digital printing systems useful for ink printing include a rotatable charge-retentive reimageable surface layer configured to receive a layer of fountain solution. The fountain solution is carried to the charge retentive surface by a fog or mist including fountain solution aerosol particles, dispersed gas particles, and charge directors that impart charge to the fountain solution aerosol particles. The charge-retentive reimageable surface may be charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged fountain solution adheres to portions of the charge-retentive reimageable surface according to the electrostatic latent image to form a fountain solution image thereon. The fountain solution image can be partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate.
