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 provided are a novel system and method for determining a sensitivity matrix for adaptive color control in a color marking device capable of performing device independent color correction. In one embodiment, a determination is made as to what control operation the color marking device is being characterized for. Nominal CMYK values are then selected based on the determined control operation. If the control operation is a gray balancing operation, the nominal CMYK values are selected using C=M=Y=L* and K*=0 values. Otherwise, the nominal CMYK values are selected using a CMYK to L*a*b* printer map. Color parameters are determined for the CMYK values based on the selected nominal CMYK values. A sensitivity matrix is then generated from the color parameters and CMYK values. The method facilitates calibration of dynamically varying color reproduction devices.

摘要： An automatic gray balance control system to produce TRCs for all primary colors in a reproduction device and for each pitch of a photoreceptor system by printing target patches for each pitch, measuring the output colors, and automatically readjusting the tone reproduction curves until a satisfactory level of accuracy is obtained as compared to the theoretical desired output. The system produces pitch-based gray balanced TRCs that are updated frequently for each pitch, with different TRCs for different pitches, to ensure consistency in output from pitch to pitch as well as from page to page on a given pitch.

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.
