Abstract: A reimageable printing member such as a printing plate for use in flexography, includes a layer having a multiplicity of channels therein. The layer has an open side to which the multiplicity of channels are open. The reimageable printing member further includes a filed generator such as an electrode or a magnetic field generator associated with the multiplicity of channels and generating an electric and/or magnetic field. The multiplicity of channels are individually addressable, thereby permitting the field to be applied to selected ones of the multiplicity of channels so that the marking material within such selected channels can be manipulated to move out of the channel and onto an image receiving substrate brought into contact with the open side of the layer, thereby forming an image on the substrate.

Abstract: A reimageable printing member such as for use in flexography, includes a layer having a multiplicity of holes, wherein the holes include therein a dimension change material and a printing material upon the dimension change material. Thus, the holes house vertically expandable units, the top portion of which is capable of protruding out of an opening of the hole at a top surface of the layer. Each of the holes may be individually addressed to provide a stimulus that initiates a change in dimension in the dimension change material. In this manner, selected ones of the units may be made to print a corresponding portion of an image on an image receiving substrate brought into contact with the printing member.

Abstract: Error diffusion halftoning systems and methods propagate the error both within a color layer and between the color layer being halftoned and subsequent color layers yet to be halftoned. Threshold array halftoning systems and methods diffuse error to subsequent color layers after a color layer has been halftoned using a threshold array. A color continuous tone image is separated into color layers. A plurality of weighting factors are selected that control how error is diffused to subsequent color layers as each color layer is halftoned. A first color layer is halftoned using error diffusion or threshold array halftoning. An error layer is generated from the first halftoned color layer and the first color layer. A modified second continuous tone color layer is generated based on at least one error layer and the corresponding weighting factor. That modified second continuous tone color layer is then halftoned and the process is repeated.

Abstract: Methods and systems formulate the impedance for decoupling capacitors of a multiple power supply printed circuit board considering plane capacitance, series resonant frequencies, parallel resonant frequencies and impedance. The impedances are evaluated at anti-resonant frequencies, which have been found to be the problematic frequencies and potentials for high impedance. Once such impedance at selected frequencies have been determined, they can be compared to target values, set for example by various system integrity or EMI standards or design parameters, to assess whether a particular DC power supply system performs properly from signal integrity or electromagnetic radiation points of view. This ability to readily assess a high probability of compliance theoretically will reduce research and development time and budget, reducing possibly many iterations of board designs and trials and error physical testing.

Abstract: A Gamut Enhance Module (GME) is disclosed for applying 3 independent Tone Reproduction Curves (TRC) to each of the color components of an input image. The implementation is done via three independent and fully programmable 1D lookup tables. The input to the Gamut Enhance Module is the output DSS from a Scaling Module (SCL), representing a scaled and de-screened version of the source image. The output is a gamut-mapped signal GME. The GME unit includes special logic to neutralize (set to gray) or preserve input colors.

Abstract: A server on a network controls a database which functions as an “asset manager” for a large population of items or assets. For “network” assets which are capable of electronically communicating data about themselves, such as computers and digital printers, relevant data is gathered over the network and entered into the database. For “non-network” assets which are not capable of electronic communication, such as typewriters and furniture, information is gathered into the database by other means. Within the database, the distinction between network and non-network assets is largely hidden.

Abstract: A method of improving black print quality in a color printer having at least one color ink and black ink includes determining a location on a substrate where a black pixel is to be printed, printing a droplet of color ink at the location, and printing a droplet of black ink with the color droplet. If the color printer includes cyan, magenta and yellow, then a droplet of cyan ink, magenta ink or yellow ink may be printed with the droplet of black ink. For images containing black at a plurality of locations, the cyan, magenta and yellow droplets may be equally distributed among the plurality of locations. Alternatively, the cyan, magenta and yellow droplets may be distributed in accordance with a digital halftone screen.

Abstract: A page to be printed is organized into a plurality of strips. To rendered the page using a tandem printer, each strip is rendered a plurality of times, once for each print engine of the tandem printer. Each time the selected strip is rendered for a different one of the print engines, the rendered image data for that print engine is stored into a separate memory area, such as a buffer, associated with that print engine Once a selected strip is rendered and the rendered image data stored into the associated memory areas, the rendered image data is used by the appropriate print engines to form image portions on a receiving sheet corresponding to the rendered image data. At the same time, a next strip is selected and repeatedly rendered for each of the print engines.

A 4DLUT reset section 7 resets some of data in the prepared K preservation 4DLUT, whereby partial calorimetric match is intended.

Abstract: An image processing device is structured such that an appropriate judgement of an image, at which blurring or disappearance or the like will occur, is possible. When pixels, which form a line image at which there is the possibility that blurring or disappearance will occur at the time of printing by using a printing plate, are extracted, a line image warning function gives notice by displaying a warning message on a monitor of a client terminal. Thereafter, image converting and print setting are carried out such that an extracted line image is clarified. In this way, when a proof is prepared, an image, at which there is the possibility that blurring or disappearance will occur on a printed matter obtained by using a printing plate, is clarified, and appropriate proofing is possible.

Abstract: Detecting skew and determining skew angle using the front of a document by determining background-to-document transitions. Incoming scanlines are interval sampled in the fast scan direction every nth pixel. The samples are collected and organized into a two dimension array comprised of scanline based rows and interval based columns. The collected and organized samples are analyzed by intervals to determine a scanline (row) where a specified sampling condition exceeds predetermined threshold. The corresponding row-interval point forms a background-to-medium transition point of the edge of a document. When two or more background-to-medium transition points are found from different intervals the skew angle can be determined using linear regression.

Abstract: What is disclosed is a method for presenting spreadsheets and other documents on client-side devices with limited resources and tiny display screen area. The present invention involves the user, on a client-side device, scrolling through a condensed image view of a document with the user's viewpoint of the image repeatedly computed server-side. A split-bar is stitched into a composite view of the user's current viewpoint. The user clicks a scroll-bar or scroll-points to indicate an intended change in direction of their current viewpoint. The client-side device provides the server with information as to where and how the next viewpoint is to be updated. Responsive to the received client information the server updates the viewpoint currently displayed with the transmission of images therefor and provides the same back to the client. In such a manner, the computing power and resources of the server are utilized for the image manipulation, cropping, etc. rather than that of the client's handheld device.
