    Abstract: A cleaning apparatus includes an inker roller and an ink source holding ink for the inker roller. The inker roller contacts a reimageable surface of an imaging member downstream of an ink image transfer station that transfers an ink image from the surface to a print sheet, with the surface having residual ink remaining thereon after the transfer of the ink image. The inker roller applies ink from the ink source against the reimageable surface. However, instead of the ink transferring from the inker roller to the surface, the ink stays with the inker roller and removes the residual ink from the surface to clean the surface for a subsequent ink image. The inker roller is not contaminated from removing the residual ink as the inker roller is designed to be coated by ink that adds to its coating of ink via the removed residual ink.

    Abstract: Examples of the preferred embodiments use printed content (e.g., halftones, difference in grayscale or darkness) to determine thickness of fountain solution applied by a fountain solution applicator on an imaging member surface and/or determine image forming device real-time image forming modifications for subsequent printings. For example, in real-time during the printing of a print job, a sensor may measure halftones or grayscale differences between printed content and non-printed content of a current printing on print substrate. Based on this measurement of printed content output from the image forming device, the image forming device may adjust image forming (e.g., fountain solution deposition flow rate, imaging member rotation speed) to reach or maintain a preferred fountain solution thickness on the imaging member surface for subsequent (e.g., next) printings of the print job.

    Abstract: Apparatus and method for using a line laser (LL) to quickly mark a substrate or media by utilizing a laser additive on/within the substrate/media, which greatly reduces the power requirement for marking the substrate/media. The combination of the LL wide swath (>305 mm) and the improved media/surface sensitivity to laser wavelength allows the LL marking system to achieve faster marking than other systems. The LL is mounted over a transport which transports the sensitized substrate/media past the LL for marking. The desired image is projected from the LL line by line in synch with the moving media and once the media passes the beam path of the LL, marking is complete. In this case, the media has been physically-altered via the heat generated by the LL interacting with the photosensitized media and is permanent. A second method would use a photosensitizing agent coated on top of the media to be marked.

    Abstract: A solid blanket receives a flood layer of very thin (e.g., about 10 μm or less) image receiving UV curable coating, which may be a clear, substantially clear, or tinted UV ink. A lower viscosity digital ink image may then be printed on top of the flood layer, for example by jetting UV ink on top of the flood layer. The lower viscosity UV digital ink sits on top of the thicker UV curable coating and maintains its location by surface tension interaction with the coating. The combination of ink and coating is then partially cured to a tacky state at which point it is transferred to print media via a conformable pressure nip. Since the lower viscosity jetted inks are not responsible for directly wetting the media, media latitude widens greatly. Further, no dampening fluid or fountain solution is needed to aid the transfer or the imaging.
