ABSTRACT:
A first, second and third color component image are each recorded line-by-line on a reproduction carrier during scanning of the original as the reproduction carrier is transported past a first, second and third recording station respectively. The recording is achieved by an intensity modulated beam deflected in a direction perpendicular to the direction of transport. To superimpose the second and third color component image exactly onto the first color component image, a mark is created either at the first recording station or prior to the time the reproduction carrier arrives at the first recording station. The mark is sensed at least at the second and third recording station and a sawtooth generator started when the mark is sensed and stopped with the vertical trigger pulse of the beam deflection system used to adjust the position of the beam in the direction of transport of the reproduction carrier. In the line direction the starting position of the beam is controlled by a position signal having an amplitude corresponding to the distance in the horizontal direction between the mark and the start of a line of the first color component image.
