What is disclosed is a novel system and method for controlling process color in a color adjustment system in an image marking device. A control parameter, such as a gain matrix, forms a basis of an adaptive closed-loop controller. A sensitivity matrix is used to calculate the gain matrix. This permits complex color adjustments at a customer location. The present system and method is well suited for long production runs because, as the system moves (or drifts) away from nominal, the color control system will learn the changes in the system (e.g., new input-output sensitivity) with print, measure, and prediction processes, operating on the test patches, and effectively adapt to these changes by re-computing the feedback controller gains and revising the current actuator values to follow desired target color values. The present system and method can also be used for adjusting or developing a CMYK recipe in color management LUTs. |
