20130050390 | Single-Pass Imaging Method With Image Data Scrolling For Improved Resolution Contrast And Exposure Extent - A method for generating an elongated concentrated scan image on an imaging surface of a scan structure (e.g., a drum cylinder) in an imaging (e.g., xerographic or lithographic) apparatus, wherein the imaging surface is caused to move in a cross-scan (process) direction. A spatial light modulator having a two-dimensional array of light modulating elements is used to modulate a two-dimensional light field in response to predetermined scan image data, and then the modulated light is anamorphically imaged and concentrated onto an elongated imaging region defined on the imaging surface. To avoid smearing, movement of the imaging surface is synchronized with the modulated states of the light modulating elements such that image features of the scan image are scrolled (moved in the cross-scan direction) at the same rate as the cross-scan movement of the imaging surface, whereby the features remain coincident with the same portion of the imaging surface. | 02-28-2013 |
20130050799 | Single-Pass Imaging System Using Spatial Light Modulator Anamorphic Projection Optics - A single-pass imaging system for a printing apparatus capable of 1200 dpi or greater that includes a homogenous light generator for generating homogenous light from high energy IR lasers, a spatial light modulator including light modulating elements arranged in a two-dimensional array, and an anamorphic optical system. The light modulating elements are disposed such that each modulating element receives an associated homogenous light portion, and is individually adjustable between an “on” modulated state and an “off” modulated state, whereby in the “on” modulated state each modulating element modulates its received homogenous light portion such that an associated modulated light portion is directed onto a corresponding region of the anamorphic optical system. In the second modulated state, the associated homogenous light portion is prevented (e.g., blocked) from passing to the anamorphic optical system. The anamorphic optical system then anamorphically concentrates the modulated light portions to form a scan line image. | 02-28-2013 |
20130050800 | MULTIPLE LINE SINGLE-PASS IMAGING USING SPATIAL LIGHT MODULATOR AND ANAMORPHIC PROJECTION OPTICS - Two substantially one-dimensional scan line images are simultaneously generated by modulating a two-dimensional homogenous light field using a spatial light modulator having light modulating elements arranged in a plurality of rows and a plurality of columns. An upper group of modulating elements are configured using a first scan line image data group, and a lower group of modulating elements are configured using a second scan line image data group. The homogenous light source is then pulsed (toggled) to direct the two-dimensional homogenous light field onto the spatial light modulator. The resulting two-dimensional modulated light field is directed through an anamorphic optical system, which images and concentrates the modulated light on an imaging surface such that two parallel one-dimensional scan line images are simultaneously formed on the imaging surface. | 02-28-2013 |
20130050803 | Variable Length Imaging Apparatus Using Electronically Registered And Stitched Single-Pass Imaging Systems - An imaging apparatus including multiple spatial light modulators, each including light modulating elements arranged in two-dimensional array disposed in a homogenous light field, multiple anamorphic optical systems, each disposed downstream from an associated spatial light modulator, a scan structure, and an image stitching controller. The light modulating elements of each spatial light modulator are individually adjustable to either pass received homogenous light portions to the anamorphic optical systems, or to block/redirect the homogenous light portions, thereby generating a two-dimensional modulated light field. Each anamorphic optical system images and focuses received modulated light field onto an associated substantially one-dimensional scan line portion on the scan structure. The image stitching controller modifies the image data sent to each spatial light modulator such that selected light modulating elements are enabled or disabled, thereby electronically stitching the scan line portions to form a seamlessly stitched scan line image. | 02-28-2013 |
20130081549 | KEYLESS INKING METHODS, APPARATUS, AND SYSTEMS WITH CHAMBER BLADE SYSTEM SPANNING ANILOX ROLL AND FORM ROLL FOR DIGITAL OFFSET PRINTING - 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. | 04-04-2013 |
20130294803 | METHOD AND APPARATUS FOR GENERATING DIFFERENTIAL GLOSS IMAGE USING LASER ENERGY - A method and system for enabling an image production device to generate differential gloss for a print includes exposing a toner image of a material to laser to cause one or more portions of the toner image to melt. The material includes the toner image and a substrate. The substrate is to remain substantially unaffected by the laser. | 11-07-2013 |

20140272121 | Digital 3D Fabrication Using Multi-Layered Mold - A replica 3D structure is fabricated inside a multi-layered mold by patterning each mold layer to define a void/opening that matches a corresponding cross section of the structure's peripheral surface, and filling the patterned opening of each layer with a structural material (i.e., before depositing a subsequent layer of mold material). The mold material (e.g., photoresist or another dissolvable sacrificial material) is blanket deposited (e.g., by slot-die, spray coating) and then patterned using a laser or a printed mask. Each layer of modeling material (e.g., polymer, ceramic or metal, or a combination thereof) is electro-plated or otherwise deposited on the previously formed modeling material layer. High vertical resolution is achieved by utilizing relatively thin mold layers. The mold layer deposition, patterning and modeling material deposition is repeated until the replica 3D structure is entirely formed inside the multi-layered mold, and then the mold is dissolved or otherwise removed. | 09-18-2014 |
