A halftone image is recorded on a photosensitive material by exposing the image to secondary exposing beam that is obtained by imparting to a primary beam two types of intensity modulation. The intensity modulation establishes a transmissivity distribution equivalent to that of a contact screen to which the halftone image is exposed.
