摘要： An algorithmic method is identified for compensating for thermochromaticity errors in insitu spectral color measurements of a color printing device. A difference is mapped between spectral measurements of a printed color generated by the color printing device measured at a first or hot temperature and at a second or cool ambient temperature where the mapping comprises a referenceable characteristic of the color printing device. The spectrophotometric measurement of a hot color is compared with colors obtained with thermochromaticity compensation matrix to assess if the measured color corresponds to the desired color which will result when cooled to ambient temperature.

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： 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： A method for estimating color measurements of color samples includes printing a color sample based on input data, measuring a color of the printed color sample with an in-line spectral sensor at a first temperature, and estimating a color of the printed color sample which would be output by a reference spectral sensor at a second temperature. The estimation is based on a thermochromatic model which represents relationships between measured colors of printed color samples on the in-line spectral sensor at the first temperature and the reference spectral sensor at the second temperature. The reference spectral sensor is a different type of sensor from the in-line spectral sensor, so the color response of the two spectral sensors is different, even when the measurement conditions are identical. Consequently, a set of printed spot color samples generate different measured colors at the second temperature on the in-line spectral sensor from the reference spectral sensor. The exemplary method allows these differences, as well as measurement temperature differences to be accounted for in the estimation.

摘要： What is disclosed is a novel system and method for updating a cluster model for color control. In one example embodiment, a cluster model is received and analyzed to identify clusters therein. Each of the identified clusters has an associated transform. Thereafter, in response to a threshold event having occurred, a critical cluster is identified and a critical color is identified from the cluster. Steps for identifying a critical color are more fully described herein. A selected number of patches is then printed in each of the critical colors and color measurements are obtained from the printed patches using, for instance, a colorimeter or spectrophotometer. If the color measurements have deviated beyond a defined threshold, then update the cluster model by: updating the transform associated with the cluster; redefining the number of clusters; redefining a center of any of the clusters; or redefining a boundary of the clusters.
