REGISTRATION SYSTEM FOR AN ELECTROSTATIC PRINTER/PLOTTER ABSTRACT OF THE DISCLOSURE A system for registering the primary colored images formed by a full color electrostatic plotter to create a high resolution composite color image. The print heads in the system include an active region of styli for forming image lines and left and right slack regions of styli. The active region may be shifted from side and increased in size to assure lateral regis- tration. Longitudinal registration is achieved by ad- justing the time interval between printing lines of successive primary images. Specific embodiments uti- lize line enhancement algorithms to ensure minimum line thickness in the image and to avoid the creation of artifacts in complex regions of the image and CCDs as sensors.
