摘要： What is disclosed is a system and method which addresses the problem of inheriting color management intent from a fleet color management LUT into a 4-to-4 cascaded LUT. The LUT is updated starting with a set of patches that either form a uniform or non-uniform grid of the LUT or can be projected to a uniform or non-uniform grid in the CMYK space using, e.g., PCA. A set of L*a*b* target as well a variable that serve the purpose of preserving the GCR and other elements of the fleet profile is obtained by passing the set of CMYK values to the fleet printer model. By iterating on the printer (or the printer model of the engine at the moment of the engine change) and converging to the targets, the engine device cmyk set is obtained. The LUT is formed between the uniform or non-uniform gridded CMYK and the device cmyk.

摘要： What is disclosed is a novel system and method for generating a spectral matching guide for spot color print applications. Spectral matching values are determined for spot colors obtained from a library of spot colors. A spectral matching guide is created from the spot colors and their respective spectral matching values in a manner more fully disclosed herein. Thereafter, when a user desires to render a job in a particular spot color, the associated spectral matching value for that spot color can be obtained from the spectral matching guide. In other embodiments, recommendations in the form of a suggested printer to use, a media type, a halftone screen, and other meaningful assistance can be provided for selection of spot colors for a given print/copy job that are less sensitive to varying illuminations. The present spectral matching guide provides meaningful extensions in spectral color reproduction in print/copy job environments.

摘要： A methodology is disclosed to achieve adaptive illumination independent matching of spot colors. In one embodiment, the methodology includes an iterative process to determine a variety device specific recipes for spot colors across different illumination spectra, and then automatically choosing and/or recommending the optimal recipe that provides the lowest color dispersion across a variety of illuminants under consideration. This approach may be used with a variety of gamut mapping techniques. According to a further embodiment, the methodology may be used with a ray-based gamut mapping method.

摘要： A system and method for achieving process spot color consistency using white and CMYK toners is disclosed. The present application employs traditional CMYK using the automated spot color editing approach and enhances this approach by applying a white toner to the printing substrate prior to applying the color. This new and novel method will improve the color printing technology for printing or alternately, applying the application of the white as a distinct separation layer for the color toner separations, on plastics, ceramics, woods, and other such non-paper materials.

摘要： What is disclosed is a novel system and method for performing ray-based compression mapping in a color management system. The present method compresses a color point located at or near a boundary surface of a color gamut to a point beneath the gamut surface in order to eliminate artifacts which are likely to arise from a color marking device trying to reproduce colors which are on a boundary of the device's printable gamut. The present method is directly applicable to a variety of gamut mapping strategies employed in color management systems.

摘要： Exemplary embodiments provide a roll member that includes one or more controllable cells and methods for making and using the roll member to control an image (or toner) state thereon. The controllable cells can be disposed on a roll substrate and configured in a manner that each controllable cell can be addressed individually and/or as groups. Each controllable cell can be addressable to provide a surface vibration to release toner particles adhered/attracted thereto and can also be capable of sensing the toner state of the roll member and thus to control the image or toner state. In an exemplary embodiment, the disclosed roll member can be used as a donor roll for a development system of an electrophotographic printing machine to create controlled and desired toner powder cloud for high quality image development.
