Abstract
An apparatus records a halftone area and a solid area in a single image with respective, different screen angles. Encoders (13, 14) and a coordinate value generator (16) generate coordinate values (U, V) on an image plane on a recording drum. An address generator (17), a pattern data memory (18) and a comparator (19) generate a first halftone dot signal (S.sub.da) for the halftone area. An address generator (22) and a pattern data memory (23) generate a second halftone dot signal (S.sub.db) for the solid area. A threshold data setter (20) and a comparator (21) generate a detection signal (S.sub.s) which indicates whether or not an image signal (S.sub.i) corresponds to the solid area. One of the first and second halftone dot signals (S.sub.da or S.sub.db) is selected by a selector (24) according to the detection signal (S.sub.s).
