Abstract
A modulator for modifying a scanning beam to project a halftone image onto a photosensitive surface including a sensor providing sensor signals in relation to the speed of the photosensitive surface, a converter responsive to the speed of the photosensitive surface to provide a signal representing an image quality factor for altering the modulation of the beam of the scanning system to adjust the projected image in relation to the speed of the photosensitive surface, the projected image including banding errors, and a random signal generator responsive to the sensor signals for generating random signals, the random signals altering the modulation of the beam of the scanning system to counter the banding errors on the projected image.
