Abstract
A system and method for correcting spatial banding artifacts in print images. The system includes: a light source, a spatial light modulator, a transport system for transporting a substrate on a carrier allowing the spatial light modulator to form an image on the substrate; a first encoder ( ) that attaches to the carrier and senses its movement; a second encoder ( ) attached to the drive circuit ( ) of the transport system to sense operation of the drive circuit ( ); a first circuit ( ) that receives the information from the first encoder and adjusts operation of the spatial light modulator; and a second circuit ( ) that receives the signal from the second encoder and adjusts operation of the drive circuit to coordinate movement of the substrate and the image to avoid artifacts. The method for establishing this system is also disclosed.
