Abstract:
A system and method are provided for enclosing a plurality of cleaning unit components in a moist cleaning unit environment, the plurality of cleaning unit components cooperating to employ a cleaner roller in an image forming device to facilitate effective cleaning of a reimageable surface in an image forming device using a proposed variable data digital lithographic image forming architecture. A range of solvents may be applied to a hard smooth high surface energy surface of the cleaner roll and a cleaning unit component internally positioned within the cleaning enclosure to clean the surface of the cleaner roll. Mechanical components are properly placed prior to the cleaner roll-reimageable surface nip to ensure that residual liquid on a surface of the cleaner roll is removed.
Abstract:
High resolution printing systems that utilize high power laser diode bars and digital mirror devices (DMD) require side-by-side stacking of illumination modules to stitching of the image from each module to form a longer total image width. An inline illumination optical system having a refractive prism and Total Internal Reflection (TIR) prism pair with an air gap along with a light guide transporting light beams at a compound angle to the prism pair eliminates the need for any axial rotation of the laser and light guide, and enables side-by-side module stacking. The illumination optical system includes an illumination module having a light source, the light guide, a DMD array and a Refractive TIR (RTIR) prism. The system also includes a DMD housing containing the DMD array and having a width within which the illumination module is confined to allow side-by-side stacking.

Abstract:
A system is provided for transferring a marking material from a ribbon to a substrate. The system includes a ribbon take-up device; a ribbon supply source that supplies the ribbon to the ribbon take-up device such that the ribbon is moved in a process direction; a pressure roll located between the ribbon supply source and the ribbon take-up device in the process direction, the pressure roll being configured to apply pressure to the ribbon at a pressure location when the ribbon is positioned between the pressure roll and the substrate; and a laser beam source that directs a laser beam or laser light through the pressure roll and onto the ribbon at the pressure location such that a marking portion of the ribbon is heated by the laser beams and transferred to the substrate.
Abstract:
A system and method are provided for implementing a unique scheme by which to execute digital vapor phase patterning on metals, semiconductor substrates and other surfaces using a proposed variable data digital lithographic image forming architecture or technique. For certain substrate printing and manufacturing applications, including some printed electronics applications, the disclosed schemes implement techniques to digitally pattern metal layers with bulk material properties in a manner that is aligned with underlying layers on the fly. The disclosed digital printing process may pattern a release oil on a substrate in support of a metal deposition process. Changeable patterning is implemented with an ability to modify the alignment of the patterns on-the-fly. The release layer on a drum is laser patterned in order that the patterned release layer is transferred to the substrate, or the patterning of the release layer is accomplished directly on the substrate.
Abstract:
A system and method are provided for providing an improved inker unit surface cleaning and conditioning system, including in a single anilox chamber blade system, for improving image quality, including eliminating ghosting, in a proposed variable data digital lithographic image forming architecture. Techniques are provided to remove acquired oil from an inking member. A particularly-configured containment encloses a cleaner (disturber) roller to emulsify the acquired oil on the inking roller. The cleaner roller is preferably configured with a pliable surface including a silicon roller surface over a porous base. The silicon roller (1) absorbs dampening solution oil; and (2) agitates ink that may be still held in certain cells/cavities of the inking member or roller. In embodiments, a vacuum pressure is applied to the inside of the hollow cleaner roller to better remove the residual ink and dampening solution from the inking roller.
