METHOD AND APPARATUS FOR COMPENSATION OF BANDING FROM MULTIPLE SOURCES IN MARKING PLATFORM |
摘要 |
A method for compensation of banding in a marking platform includes: initiating a calibration stage; marking a test pattern over multiple intervals of a lowest fundamental frequency among marking modules; obtaining image data for the test pattern from a sensor; obtaining 1× signals from sensors associated with the marking modules; and processing the image data in relation to the 1× signals to form banding profiles for multiple marking modules. Alternatively, the method may include: processing image data in relation to 1× signals to form banding profiles for multiple marking modules; determining amplitudes in multiple banding profiles exceeds a threshold to identify dominant banding profiles; and processing dominant banding profiles to form dominant banding signatures. Alternatively, the method may include: initiating a correction stage; obtaining 1× signals from sensors associated with dominant marking modules; and periodically processing dominant banding signatures and 1× signals to determine a banding compensation value.
