摘要： What is disclosed is a method for determining a color solution which achieves color objectives for a color marking device involves performing the following. In one embodiment, N objectives of interest are identified for a color marking device and a N-dimensional Pareto Front is constructed which comprises a collection of color solutions which accommodates those objectives. The Pareto Front is constructed using an optimization process based upon printer models of the objectives. Color solutions can be at least one color recipe, or a combination of color recipes and process actuators. A target point is selected in an N-dimensional objective space based upon at least one user-selected preference. The target point is then mapped to a point on the Pareto Front. The mapping identifies one of the color solutions which, in turn, is used to generate a spot color for the device. The generated spot color achieves the user-selected preference.

摘要： What is disclosed is a feedback control based system and method for selecting spot color recipes for improved spot color rendition while simultaneously minimizing a function of image quality attributes formed with states defined as vectors such as L*, a*, b*, mottle, graininess, etc. Color is measured with an in-line spectrophotometer or with a full/partial width array. If the sensor is not available, then a model of the print device is used to optimize the function of image quality attributes. In one example embodiment, a spot color of interest is selected along with a set of image quality attributes to be improved for the spot colors of interest. Set points for process actuators and color recipes of the color marking device are adjusted such that a function of the image quality attributes is minimized when the spot color is rendered on the device. Various workflows are disclosed.

摘要： What is disclosed is a novel system and method for retrieving a gamut mapping for a color device. A ray-based model is derived from a system estimation of either a seed profile or a seed device. The model is hard coded inside a run-time ICC profile creation algorithm. The runtime profile generation code can be optimized for a variety of gamut mapping scenarios. The generated profile is provided to an imaging system wherein out-of-gamut colors are mapped to the color gamut of the host device. The present method provides an accurate way to reproduce colors of images by retrieving the gamut mapping from profiles or from the color device that use destination profiles for rendering images.

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.

摘要： Disclosed herein are optimal or near optimal algorithms implemented as software tools that will allow the user/machine to identify optimal media out of the job set automatically. There are at least two main process steps to the exemplary embodiment. The first step involves the off-line characterization of the printing/image rendering system that will be used to extract the principal basis vectors from the experimental data. The second step involves the run-time mode, in which the pre-characterized basis vectors are used in conjunction with an optimal algorithm that will identify the media for re-calibration/re-characterization from the group of media set that the customer is interested to print. The optimal algorithm performs the combinatorial search every time the customer wishes to select the media. Once the optimal media is selected, the customer or the machine can print color patches (which are also optimal set) and execute the rest of the processing to reconstruct the best color management LUTs.
