Abstract:
A method of forming an imaging blanket for a printing apparatus comprises preparing a support structure (e.g., mold) for receipt of a polymer blanket compound, introducing the polymer blanket compound in liquid state over the support structure, curing the polymer blanket compound to produce an imaging blanket, releasing the imaging blanket from the support structure, and etching a surface of the imaging blanket to form a texture pattern therein, the surface forming an imaging surface of said imaging blanket. An imaging surface providing desirable dampening fluid retention is provided. Wet etch, dry etch or a combination of both may be used. The polymer may be a silicone compound, may include 3 percent by weight granular material.
Abstract:
A method and system is provided to extend operational life of a mirror array of an image generating system, wherein the image generating system further includes a high intensity power light source to cause light to impinge on the mirror array, sufficient to cause deleterious plastic deformation of associated hinges of the mirror array, and an image output generating section configured to receive light from the mirror array. Image date is received by the image generating system image data to control mirrors of the mirror array and to generate an output image. A required level of illumination is provided from the mirror array to the image output generating section over a predetermined time period, in accordance with the received image data. Then during at least a portion of the same predetermined time period of providing the required level of illumination from the mirror array to the image output generating section, de-stress switching operations are performed for selected ones of the mirrors of the mirror array to reduce the plastic deformation of the associated hinges. Next, an output image is generated based on the received image data, wherein the de-stress switching operations occurring during at least a portion of the providing of the desired level of illumination is undetected.

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:
An ejector device that includes one or more ejectors comprises an ejector layer that spans at least one hollow area. The ejector layer has a first surface and an opposing second surface arranged to receive a viscous material with viscosity between 20 and 50,000 centipoise. The ejector layer includes a radiation absorber material configured to thermally expand without phase transition in response to heating by activation radiation transmitted to the first surface. Thermal expansion of the ejector layer causes displacement of the ejector layer and ejection of the material from the second surface of the ejector layer.

Abstract:
An imaging blanket for a variable data lithography printing system is disclosed that comprises a polymer body having incorporated therein carbon black and measured amount of surface-treated fumed silica. The carbon black serves to improve the thermal absorption efficiency for thermal patterning of a dampening fluid layer formed over the imaging blanket in use. The surface-treated fumed silica assists with desirable dispersion of the carbon black in the polymer body. The surface-treated fumed silica further assists with the formation of a surface micro-texture as part of the process of molding the imaging blanket. A method for manufacturing such an imaging blanket is also disclosed.
