In a method for reproducing a halftone picture by scanning, wherein a brightness and a width of a recording light beam to be projected on a photosensitive material is suitably controlled by means of picture signals obtained from the scanning of an original picture, a control method for reproducing a halftone dot cut away along a picture outline is disclosed, wherein a position of an outline in an original picture is detected, wherein the intersection of the outline with a halftone dot is discriminated by comparing the two positions of the outline and the dot, and wherein a part of the dot positioned inside the outline is exposed by the recording light beam.
