摘要： What is disclosed is a novel system and method for quickly and accurately determining whether a color is inside or outside the boundary of a surface of a color gamut. The present method enables a gamut mapping algorithm to quickly identify points which require further processing and those which are already inside the gamut and thus do not need to be processed by the gamut mapping function. The present method can be performed directly on the printing device to determine whether the colors are in/out of the actual gamut surface of the target marking device. Other embodiments have also been disclosed.

摘要： What is disclosed is a system and method for mapping an out-of-gamut spot color to a surface boundary of a target color gamut of a color marking device in a color management system. The present method accurately detects the intersection of a point at the boundary surface of a ray traced between the out-of-gamut color and color point along a neutral axis of the target gamut. The ability to map an out-of-gamut color accurately to the gamut surface provides many advantages as one skilled in the art would appreciate. Various embodiments are provided.

摘要： A method and system of color management for an image marking device. A sensor measures printed hardcopy colors. A first gain, computed by a linear controller based on a linear model, is scheduled for each color node of a sampled color space. For each node where a convergence error exceeds a threshold, a second gain is scheduled by a nonlinear controller. The second gain scheduling includes initializing operational parameters, and performing an iterative procedure. The iterative procedure includes computing gain matrices over a defined projection horizon, evaluating a cost function for each gain matrix, determining the cost function, scheduling a new gain based on selecting a gain matrix having the minimum value of the cost function, and computing new CMYK values based on the new gain. A multidimensional LUT based on the scheduled gain matrices is generated and stored in memory, and a hardcopy output image is generated based on the stored multidimensional LUT.

摘要： What is disclosed is a novel system and method to reduce noise induced by color mixing in a color management system. At least one device color recipe is obtained for a target spot color. The recipe is defined for a color marking device and defines a range of marking device color values for a target L*a*b color value. Next, a minimal value and a maximum value of each color value in the range of color values for said target L*a*b color value are identified. An iterative process of searching is performed until the printed color test patch produces a visually acceptable smoothness while matching color accuracy. This iterative process includes generating at least one additional new device color recipe from color values within the range of color values. At least one of the new device color recipes is selected and provided to the color marking device for rendering.
