摘要： What is disclosed is a novel system and method for implementing a color model function for a printer that uses a relatively large number of colorants. The model is based upon several four color printer color models that contain more complete color models by storing output data for a higher number of input color value combinations and a small number of additional measurements that characterize the response of the printer to outputs using more than four colorants. Results from more complete printer models are determined and combined with a CMYKOV printer model that stores output values for only a coarse resolution of inputs. Transitions between various regions of color space defined by the colorant model definitions are then smoothed. A higher dimension printer color model output is produced. The present method effectively determines a higher dimension color printer model output corresponding to values of an N+2 dimension color model input.

摘要： What is disclosed is a novel system and method of inheriting intended GCR into a 4-to-4 cascaded LUT to compensate for print engine change which adversely impacts the quality of an output print. The present method uses the device link transform to generate starting LUT nodes for the inverse of the drifted printer model by inputting CMYK or RGB into the device link at a color space resolution sufficient to determine output nodes. Lab and CMYK values are derived from this process, and a “starting LUT” is created at the Lab destination nodes. An iterative control begins with this starting LUT to produce an inverse drifted printer model that contains a close approximation for the intended GCR. The present method captures the intent of the device link transform for a fleet and generates the cascaded LUT for drift, specific printer, side1/side2, and other modes leading to special GCRs.

摘要： What is disclosed is a system and method for merit-based gamut mapping. In one embodiment, color points are clustered in regions of interest within a color space. Each cluster is associated with a gamut mapping function and a merit function. Mapping parameters of each gamut mapping function are iteratively varied to optimize the values based on the merit function value. An optimized gamut mapping function results. Optimized gamut mapping functions of adjacent clusters are blended together by blending the value of the gamut mapping function for a point of a cluster with a value produced by the gamut mapping function of an adjacent cluster for that color point. The composite gamut mapping function contains the optimized gamut mapping functions of all clusters is then output for use in mapping points within those clusters to points within the target gamut. The composite gamut mapping function exploits local advantages of each cluster.

摘要： What is disclosed is a novel system and method for converting a set of L*a*b* values to CMYK color space in which all CMYK formulations that produce each L*a*b* value are found and enumerated. The CMYK formulations are found through a search algorithm starting with the lightest L*a*b* values then visiting neighboring L*a*b* values until the entire L*a*b* color set has been processed. The CMYK space is tessellated into a set of pentahedrons, and for each L*a*b* value, an enclosing pentahedron is found and the CMYK values corresponding to where the locus of this point penetrates each surface is recorded. Adjacent pentahedrons are then visited and this process continues until the gamut boundary is reached. The result is a piecewise linear representation of the CMYK locus containing all values that will give the target L*a*b* value. The present method provides a flexible and powerful approach for solving color management problems.

摘要： A computerized system, method, and software apparatus is presented which reduces the black level of the printing process in order to substantially remove stray black dots from the finished product of a printing output. Black levels are reduced by updating the print engine regions for the colors W, C, M, Y, MY, CM, CY, and neutral and by assigning a weights each color. The values are used to compute CMKY values. These values are then placed in a gain matrix and stored in a computer memory.

摘要： Systems and methods are disclosed of a smooth gray component replacement strategy which utilizes the full gamut of a printer device. A CMY to CMYK gray component replacement transform is disclosed which inherently exploits the full gamut of the printer, by transforming points in CMY cube to L*a*b* color space, scaling the obtained values so they fill the maximum gamut obtainable with the printer device and calculating the CMYK values needed to obtain the scaled L*a*b* values. The CMY to CMYK transform is then smoothed with an averaging filter that does not change CMYK values at the corners. The entire color gamut is adequately sampled and small changes in CMY do not produce large jumps in L*a*b*.

摘要： A transformation function defines a relationship between a first color space and a second color space. The transformation function is edited by producing first and second outputs of an image in the first and second color spaces, respectively. The outputs are related in accordance with the transformation function. A portion of the first output, which corresponds to a portion of the second output including a color to be modified, is selected via a graphical user interface. A desired amount to modify the color is specified. A correction function is determined in accordance with the desired amount. The transformation table is edited in accordance with the monotonic correction function.
