  • Patent number: 7190827
    Abstract: A color space conversion technique uses a set of control lines in a first color space. Each control line includes several control points having predetermined values in a second color space. A planar region is identified among the set of control lines in the first color space. The planar region contains a number of target points that are to be interpolated from the first color space to the second color space. The planar region is partitioned into at least a first area and a quadrangular area. Target points in the quadrangular area correspond to a different set of colorants from the second color space than target points in the first area. A quadrangular interpolation is applied to the target points in the quadrangular area to determine corresponding values in the second color space based at least in part on the predetermined values of control points bounding the quadrangular area.

  • Patent number: 7161719
    Abstract: A generalized color calibration architecture and method are disclosed. A first interface receives raw measuring data of a sample from a measuring tool. The data has a color type, and the sample has one or more color targets. Each color target has an arrangement of one or more color patches. A second interface receives the color data type, one or more target identifiers specifying the targets, and a color patch order for each target identifier. The color patch order specifies the arrangement of the color patches of a corresponding color target. A color calibration manager performs the color calibration based on the raw measuring data, the color data type, the target identifiers, and the color patch order for each target identifier. The calibration yields or updates one or more color conversion tables for subsequent use with a device, such as a color printer, or another type of device.

  • Patent number: 7054035
    Abstract: A method of mapping a color produced by an image device in a presentation color space to a destination color space including steps of receiving the color from the image device, determining if color is to be preserved, converting the color to the destination color space using a default profile if it is determined that color is to be preserved, and converting the color to the destination color space using a device-specific profile absent a determination that color is to be preserved.

  • Patent number: 7023584
    Abstract: A method, includes depositing a first quantity of a first colorant corresponding to a first color value and a second quantity of a second colorant corresponding to a second color value on a region of media, determining a value related to a hue of the region, determining a difference between the value and a predetermined value. In addition, the method includes changing an association between the first color value and a first colorant quantity value, corresponding to the first quantity of the first colorant, according to the difference. An apparatus includes a spectral measurement device configured to generate output corresponding to a spectral content of light reflected from a region on media formed by depositing a first quantity of a first colorant and a second quantity of a second colorant onto the media. In addition, the apparatus includes a memory to store a plurality of color values and a corresponding plurality of first colorant quantity values.

  • Patent number: 6980328
    Abstract: A color printing system and method for reducing bidirectional hue shift in inkjet printing. A set of data channels for the ink colors of the system is generated, including at least one print-direction-independent data channel, and at least one pair of print-direction-dependent data channels. A print controller receives the set of data channels for printing, and selects the print-direction-independent data channels, and one of each pair of print-direction-dependent data channels, to provide the data for printing in each opposite scanning direction of the print engine.

  • Patent number: 6848688
    Abstract: Multiple sheet set compiling in a compiler of the seriatim output of printed sheets from a printer with a sheet entry position and a lateral sheet tamping system for laterally tamping the sheets being stacked in the compiler, in which the accumulated stack height of the sheets being compiled is estimated, and in response thereto the height of the top of the lateral sheet tamping system is raised to be maintained above the top of that rising (thicker) stack in the compiler, and lowered for the initial sheets stacking, and the compiler sheet entry position is also automatically raised in proportion to the increasing height of the stack of sheets being compiled in the compiler.

  • Patent number: 6840420
    Abstract: A device for holding a badge and an identification card includes a first strip of material constructed of leather. The first strip of material is shaped to include first and second generally oval-shaped portions which are connected through a neck. The first portion is shaped to include a pair of openings through which the badge can be pinned. A second strip of material constructed of leather is sewn onto the first strip of material along three sides so as to define a generally rectangular-shaped pocket for receiving the identification card, the first strip of material being shaped to include a centered window to display the identification card when disposed within the pocket. The first strip of material can be folded about the neck to form a closed loop. A pair of complementary fasteners are mounted onto the first strip of material to retain the device in its closed loop configuration.

  • Patent number: 6801337
    Abstract: Optimally determined halftoning algorithms are applied to tone values by selecting among combinations of at least two algorithms that best address the tradeoff between output quality and rendering performance. Input tone values are scrutinized and matched with the algorithm combination that processes the associated tone values in a manner that increases performance (including data compressibility) without sacrificing output quality. The selection process is computationally simple and fast. Reliability is ensured because the combinations of halftoning algorithms are tabulated as a result of analysis of test samples of the printed output.

  • Publication number: 20040113349
    Abstract: A disk stacker system for delivering selectively inverted substrate assemblies into a receiving tray. By alternating inverted with non-inverted substrate assemblies or otherwise grouping inverted and non-inverted substrate assemblies, handling of folded printed material is made more efficient and packing of the folded printed material is made more dense and efficient. The disk stacker system operates by delivering selected substrate assemblies directly to the output tray and bypassing the disk stacker inverting apparatus and by delivering other substrate assemblies to the disk stacker apparatus for inversion prior to delivery to the output tray.
