ABSTRACT:
Reproductions of originals are obtained electro-photographically by exposing a charged photoconductor sequentially to at least two electro-optically regulated laser beam exposures, each exposure representing a separate color component of the original. Full color reproduction is possible.
Alternatively a laser beam exposure may be accompanied, preferably substantially simultaneously, by exposures from either an opaque original or a transparency or both.
