摘要： A reimageable layer of an imaging member is provided with a dampening fluid layer. The reimageable layer has specific properties such as composition, surface profile, and so on so as to be well suited for receipt and carrying the dampening fluid layer. An optical patterning subsystem such as a scanned modulated laser patterns the dampening fluid layer. Ink having a first set of properties such as color, composition, etc., is applied at an inking subsystem such that it selectively resides in voids formed by the patterning subsystem in the dampening fluid layer to thereby form an inked latent image. The inked latent image is then transferred to a substrate, and the reimageable surface cleaned. The process is repeated for a second ink having properties different than the first. Each ink image may successively be applied to the substrate, or a composite image may be formed then applied to the substrate.

摘要： A chamber blade system maximizes ink flow at an anilox doctor blade by including a heating element adjacent the doctor blade to heat ink adjacent the blade. The heating element may be a heat strip next to an anilox doctor blade that heats the ink adjacent the doctor blade and temporarily reduces the ink viscosity to improve the flow of ink in the vicinity of the blade. Doctoring blades with a ceramic tip coating may be configured to allow a small amount of controlled ink flow through that can wet the lands thereby reducing the hydrodynamic back pressures and friction when trying to force the ink into anilox cells.

摘要： A dampening fluid useful in offset ink printing applications contains water and a surfactant whose structure can be altered. The alteration in structure aids in reducing accumulation of the surfactant on the surface of an imaging member. The surfactant can be decomposed, switched between cis-trans states, or polymerizable with ink that is subsequently placed on the surface.

摘要： 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.

摘要： An apparatus and method for providing rewritable printing by utilizing nanoparticles at the printing plate to reduce power requirements for imaging modules in a variable data lithography system is provided. The disclosed embodiments propose a printing plate surface that is made up of an elastomer and incorporates engineered nanoparticles that have high optical absorption properties to improve ablation performance. The exact material, composition and geometry of the engineered nanoparticles are optimized for the specified imaging module without altering plate properties. The apparatus and method use electromagnetic radiation coupled with a nano-filler to locally apply heat to a dampening solution on the printing plate to form a latent image. The nanoparticles do not undergo a physical or chemical change beyond heating up.

摘要： An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. A process for variable data lithographic printing includes applying a dampening fluid to an imaging member surface; forming a latent image by evaporating the dampening fluid from selective locations on the imaging member surface to form hydrophobic non-image areas and hydrophilic image areas; developing the latent image by applying an ink composition comprising an ink component to the hydrophilic image areas, the ink composition comprising a high viscosity thickening agent to raise the viscosity of the composition from about 1.05 to about 2 times higher while maintaining excellent transfer to a substrate at low temperatures.

摘要： A variable lithographic cleaning apparatus, system and method works on the principle that dust and ink residue may be transferred from a lower surface energy reimageable conformable blanket surface to a higher surface energy surface low durometer cleaning member, such as the tacky roller, and then to an even higher surface energy cleaning member, such as the hard roller, which is hard and robust to scratching. The hard roller can then been scrubbed clean by an ink flushing device having a third cleaning member, such as a melamine sponge, wetted with a cleaning solution with the hard roller dried upon each rotation.

摘要： A variable lithographic inking system includes a chamber blade system configured to supply ink to an anilox member of an inking system. The inking system includes a soft ink transfer roll and a hard form roll. Ink is transferred from the anilox roll to the form roll by way of the transfer roll, and from the form roll to a reimageable surface layer of an imaging member of a variable data lithographic system. An ink layer free of ink history is uniformly applied onto a surface of the form roll, and subsequently transferred to the reimageable surface layer while avoiding or substantially eliminating image ghosting related to inking non-uniformities.

摘要： 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.
