Abstract
A method of correcting periodic banding defects in a printing system is provided. The method comprises: determining a banding profile estimate; determining a compensation profile; adjusting the compensation profile based on the transfer function of a motion system and the transfer function of a printing system; waiting until a defect once-around signal returns; and applying the output of the adjustment step to a controller controlling the speed of an imaging surface.
