Abstract: The present disclosure is drawn to printing systems. In one example, a printing system can include an inkjet print head and a plasma generator. The inkjet print head can be used to form a printed image on a media substrate. The plasma generator can be positioned with respect to the inkjet print head to treat the printed image after application to the media substrate.

Abstract: An improved end-seal carrier assembly for supporting a seal in a seal-type continuous dampener. The seal is supported by a backing plate and pressed against the ends of the dampener's rollers. A carrier shaft is fixedly mounted to the backing plate. A shaft housing is mounted to the sideframe and has a hole extending longitudinally there through into which the shaft is mounted so to rotationally and longitudinally translate with respect to the sideframe. A coil spring is wound about a portion of the carrier shaft and has a first spring end operatively engaging the backing plate and a second spring end operatively engaging the shaft housing. The coil spring is configured to induce both a compressive and torsional bias between the backing plate and the sideframe. The shaft housing is rotatable for winding the coil spring and thereby establishing the torsional bias.

Abstract: The occurrence of offsetting and strike-through in a stencil printing device is prevented without creating any new problems, and the printing paper is allowed to be conveyed with a pair of rollers interposing the printing paper for a reliable paper ejection process. Printing paper P is passed through a nip between a contact roller 37 and a counter roller 39 opposing the contact roller 37, the outer circumferential surface of the contact roller being coated with a layer of excess ink removing liquid which does not dissolve with the printing ink forming the printed image and has smaller surface tension than the printing ink, and the contact between the excess ink removing liquid layer a of the contact roller 37 and the printed surface of the printing paper P causes the excess portion of the printing ink b deposited on the printed image of the printing paper to be transferred onto the excess ink removing liquid layer a so as to remove the excess ink from the printing paper P. The contact roller may be replaced with an endless contact belt 83.

Abstract: A printing press and a method operating the same. The printing press includes: a frame; a plate cylinder being rotatably mounted on the frame; an inking unit for supplying ink to the plate cylinder. The inking unit comprises: an ink fountain for containing ink; a plurality of inking rollers; means for transferring ink between said ink fountain and said plurality of inking rollers; a plurality of ink applicator rollers for transferring ink between said plurality of inking rollers and said plate cylinder. The printing press further includes a dampening unit for supplying damping medium to said plate cylinder. The dampening unit comprises a form roller having an elastic outer cylindrical surface which can be engaged at the printing plate of a plate cylinder, a driven dampening distributor having a chromium outer cylindrical surface and being assigned to the form roller, and further dampening-unit rollers supplying the form roller with the dampening medium contained in a dampening-medium vessel. The dampening distributor is preferably provided with cups arranged close to each other and preferably featuring each a depth of approximately 20 micrometers, and, preferably, the ridges between the cups: are rounded off; permeate the dampening-medium film and the ink film on the form roller; and, under a certain contact pressure, are in contact with the outer cylindrical surface of the form roller and drive the form roller.

Abstract: An ink-based digital printing system includes a dampening fluid delivery system that forms a dampening fluid layer on a reimageable surface of an imaging plate using vapor condensation. The system includes a delivery nozzle having a chamber that receives atomized dampening fluid, mixes the fluid with hot air or nitrogen gas for rapid vaporization, and directs the vapor onto an imaging member surface for condensation and dampening fluid layer formation.

Abstract: A printing unit includes a press unit having a forme cylinder, a transfer cylinder, an inking unit and, preferably, a damping unit. The inking unit of each press unit applies printing ink to a forme cylinder of the respective press unit in such a way that a ductor roll of an inking unit picks up printing ink kept ready in an ink fountain and applies it to the forme cylinder of the respective press unit by a film roll interacting with the ductor roll, inking unit rolls arranged downstream of the film roll, and at least one ink applicator roll rolling on the forme cylinder. Inking unit rolls driven in rotation and inking unit rolls driven in oscillation are are driven independently from one another on the drive side.
