What is disclosed is a novel system and method for banding defect detection in user document images to improve image quality trend analysis in multifunction digital imaging system architectures. The present banding detection process uses region-based, time sequence analysis, and graylevels of image regions in a collection of a sequence of regions, to improve banding detection. The present method independently analyzes the colorant separations to detect banding due to sources that are colorant-dependent, e.g., due to a single developer housing. This identification can be performed in the presence of multiple banding defects.
