Patent ID: 8422899

Claim:
A method for compensation of banding in a marking platform, comprising: a) initiating a calibration stage to determine banding characteristics of a marking platform, the marking platform comprising a plurality of marking modules at least a portion of which are select marking modules, wherein each select marking module is provisioned with at least one once around sensor and each once around sensor is adapted to provide a 1x signal indicative of a fundamental frequency for banding characteristics associated with the corresponding select marking module; b) marking a banding test pattern on an image receiving member over at least multiple intervals of a lowest fundamental frequency among the select marking modules; c) obtaining banding image data for the banding test pattern from a test pattern image sensor in conjunction with the marking in b); d) obtaining 1x signals from each once around sensor in conjunction with the marking in b); and e) processing the banding image data in relation to the 1x signals to form a banding profile for each of two or more select marking modules, wherein the fundamental frequency associated with each 1x signal is used to determine banding characteristics attributed to the corresponding select marking module and filter banding characteristics not attributed to the corresponding select marking module for the corresponding banding profile, each banding profile reflecting a phase relation of amplitude banding characteristics to the corresponding fundamental frequency in relation to the banding test pattern.
