ABSTRACT:
A system that permits the plotting of any combination of several colors in one pass. Three differently colored light sources are provided, and thus one, two or three colors may be plotted at the same time. An apparatus is provided for causing relative movement between the scanning head and the substrate along each of the two axes of the substrate. Preferably, the first axis is disposed circumferentially about a cylinder, on which the substrate is situated, the cylinder having a central axis, and the second axis is disposed approximately parallel to the central axis. The system includes deflection means, preferably acousto-optical modulators, for deflecting along a path a portion of each beam of light by an amount dependent upon the frequency of a signal that is present at the deflection means' input.
