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.
