    摘要: A printing device is requested to generate a calibration test print. The printer generates a plurality of color patches and identification data which are put in hard copy form by a marker. The identification data includes data such as device identifiers, calibration print identifiers, and calibration statistics for the printing device. The hard copy calibration print is scanned and is transmitted to a calibration server. The calibration server interprets the coded data and determines the originating device, the calibration pattern printed, and an optimal color pattern based on the identification data. The color pattern printed is then compared to the optimal color pattern and their differences are determined. A color correction table is generated based on the differences and transmitted to the network address of the originating printer based on the identification data. The identification data provides for automatic recalibration of printing devices on a network.

    摘要: A method and apparatus for identifying regions within a first binary image where half-bitting may be present, converting those regions to a multiple-bit/pixel representation so as to accurately represent the image density and the intended edge structure for the region, and further generating an enhanced resolution representation of the region in either a second binary image, wherein the second binary image has a spatial resolution greater than the first image, or a multiple-bit per pixel (gray) image at the same resolution as the input image so as to enable an improved rendering of the first binary image.

    摘要: The present invention is a method and apparatus for processing a color document for moire-free printing, the color document including a plurality of color separations each defined with a set of image signals representing optical density with m possible density levels, while a printer is capable of rendering density with n density levels. The invention employs a spatial resolution scaler to produce m-bit signals at a spatial resolution that is a function of the halftone screen angle, base dot pitch, and desired halftone cell size. Subsequently, the m-bit signals at the desired spatial resolution (frequency and angle) are halftoned to produce n-bit signals that are printed with a raster output scanning-type printer suitable for printing at selectively variable spots per inch in both the fast and slow scan directions.

    摘要: A dynamic power control for an external cavity stabilized laser diode adapted for use with a Raster Output Scanner employing a photodiode to convert light emitted from the rear facet of the diode internal cavity to an electrical signal, and a comparator for comparing the light intensity signal with a reference signal and adjusting the drive current input to the diode to maintain diode output pwer constant. In a second embodiment, diode power is taken from the zero order beam at the external cavity transmissive wavelength selecting grating, in a third embodiment from the external cavity output beam, and in a fourth embodiment, from the zero order beam that passes through the holographic disc facets.

    摘要: A xerographic system and method use a tri-level development process in which at least one xerographic imaging unit includes a photoreceptor and a pair of developer units. A first developer unit includes a full strength toner of a given color and a second developer unit includes a reduced strength toner of the same or substantially the same color. By use of the tri-level process, excellent color-to-color registration can be achieved for each processed color separation. Moreover, by use of two strengths of the same colorant, a tighter control of a tone reproduction curve can be achieved. Additional xerographic imaging units can include a developer unit that provides spot color, custom color or specialty color capabilities. Additional benefits and gamut expansion can be achieved through use of a tandem architecture. A preferred implementation uses a four drum, eight color tandem architecture with full strength and reduced strength toners formulations of Cyan, Magenta, Yellow, and Black (CYMK) colorant.

    摘要: A multi-purpose print platform includes a color print engine with color and black toners and a low-cost-per-page print engine having at least two image development systems in which each of the development systems is associated with a different type of black toner and/or highlight color toners. Jobs that include color and black and/or highlight color pages can be processed by using both print engines. The low-cost-per-page print engine typically is low cost in that it facilitates processing pages at a low per page cost relative to color and/or high cost black print engines while providing the productivity and reliability of a typical black only print engine.

    摘要: A printing system capable of binding a modified image data to an individual print engine in a multiple print engine system. The system includes an image processor such as a digital front end, a set of transformations, and a configuration of printers. The system can also include a scanner that scans a test image so that this image binding process can be repeated. Furthermore, the transformation binding can also take place in real time.
