摘要： The present invention relates to a color management method for the conversion of internal color appearance space color values to CMYK device values, by interpolating CMY values from a plurality of CMY to color appearance space lookup tables, wherein each CMY table is associated with a specific value of K. A target internal color value is received and the relative purity of that color is calculated in the CMY space. Next, a black generation value is calculated using the relative purity of the target color. Finally, one of the plurality of CMY lookup tables is selected based on the black generation value, and a CMYK value is provided based on an interpolation from the selected lookup table. In this way, the present invention is able to control the output K value in a color appearance space to CMYK conversion. Accordingly, colors across a wide relative purity range, including natural images, can be reproduced with better accuracy and higher quality.

摘要： Color management which uses a color conversion LUT for transformation from an N-dimensional source device color space (N≧4) to a destination device color space, in which the color conversion LUT is constructed in a two-step process. In the first step, an intermediate color conversion LUT is constructed that converts colors in a three-dimensional device-independent color space through a gamut mapping step and through an inverse destination device transform so as to obtain colors in the destination device color space. In the second step, the overall color conversion LUT is obtained by applying a source device transform to color combinations in the source device color space so as to obtain color values in the three-dimensional device-independent color space, and thereafter performing three-dimensional color look-ups in the intermediate color conversion table.

摘要： The present invention provides for determining a gamut boundary description for a color device, the color device being characterized at least by a destination transform which converts colors from a device-independent color space to a device-dependent color space and which reports out-of-gamut colors. A set of sample values is determined in the device-independent color space. For each of the sample values within the set of sample values, the destination transform is applied to the sample value, and in a case where the sample value is in gamut, the sample value is included within a set of gamut boundary values. The gamut boundary description is determined by forming a set of polygonal surfaces based on the set of gamut boundary values. Accordingly, a gamut boundary description is determined without necessarily having to sample additional color values as the number of colorant channels for the color device increases.

摘要： The present invention provides for a device model that transforms color image data between a device independent color space and a device dependent color space having n colorants. When transforming color from a device independent color space to a device dependent color space, a plurality of colorant sets is obtained, wherein each colorant set is a defined subset of the n colorants which includes some but not all of the n colorants, and wherein the number of defined subsets is smaller than the number of all possible subsets of the n colorants. A transform is generated for each of the colorant sets, wherein each transform maps to a device dependent color space corresponding to the respective colorant set. A search order can be obtained to define an order for searching the transforms. A color composition of the n colorants can be obtained to produce primary and secondary colors. Accordingly, a configurable device model for n-channel printing can be realized.

摘要： The present invention relates to a color management method for controlling the amount of black ink used by a destination device with a black channel when converting colors from one of a plurality of source device color spaces to destination device color space. This conversion is accomplished by obtaining a black weight of a source pixel in the source device color space, transforming the source pixel into a color in color appearance space, and calculating destination values based on the color in color appearance space and the obtained black weight. In the case that the source device color space does not include a black channel, the black weight is obtained from a color purity of the source pixel. In the case that the source device color space is a device space including a K channel, the black weight is obtained from the K channel.

摘要： A method and apparatus for generating transform-based color profiles by a measurement-based Color Management System (CMS). The measurement-based CMS generates the transform-based profile wherein the measurement-based color system is parameterized by color data and procedures. The CMS may use a reference Profile Connection Space (PCS) loaded from a measurement profile, thus enabling user configuration of the generation process. The reference PCS may also be set to include a gamut that is appropriate for an eventual color-output device. In addition, a Gamut Mapping Model (GMM) used in the generation process is user-selectable as well as a Device Model (DM). The DM may also be supplied as a pluggable module. The CMS also features user-selectable mapping from an International Color Consortium (ICC) intent to a PCS profile and to a DM. The features of the CMS may be used in an application, stand-alone profiling tool or in an operating system utility.

摘要： The present invention transforms a source device colorant value to a destination device colorant value, by determining whether all non-black colorant values of the source device colorant value are zero, transforming the source device colorant value to a colorimetric value using a source device model, transforming the colorimetric value to a gamut-mapped colorimetric value using a user-selectable gamut-mapping model, and selecting a destination device colorant value based on the determination. In a case where all of the non-black colorant values of the source device colorant value are zero, the destination device colorant value is selected so that its black colorant value reproduces a lightness of the gamut-mapped colorimetric value, and all of its non-black colorant values are zero. Otherwise, the destination device colorant value is selected so that a combination of its non-black and black colorant values reproduces the gamut-mapped colorimetric value. Accordingly, black content is preserved while accommodating a user-selectable gamut-mapping model.
