Abstract
An ink-based digital printing dampening fluid delivery system useful for printing with an ink-based digital printing system, the ink-based digital printing system having an imaging member, includes a supply chamber; and a supply channel, the supply channel being configured to deliver fluid onto a surface of the imaging member, wherein a width of the surface of the imaging member onto which dampening fluid is applied is twenty percent greater, or more, than a diameter of the supply chamber.
Claims8
An ink-based digital printing dampening fluid delivery system useful for printing with an ink-based digital printing system, the ink-based digital printing system having an imaging member, the system comprising:
- a supply chamber having a supply chamber interior;
- a supply channel, the supply channel defining a supply channel interior in communication with the supply chamber interior, the supply channel descending towards the imaging member at an angle of 30 degrees or less, the supply channel being configured to deliver fluid vapor onto a surface of the imaging member;
- and
- a supply channel outlet configured to enable the supply chamber interior to communicate with the surface of the imaging member, the supply channel outlet being configured to deliver dampening fluid vapor to the surface of the imaging member at an angle of 30 degrees or less by vapor deposition, the supply channel including line probes configured to report tangential velocity above a plate surface, mass fraction at the surface of the plate, and temperature at the surface of the plate.
