ABSTRACT:
The method which comprises the steps of producing a halftone dot photograph, producing a cut out photograph by cutting out a desired portion of the photograph, adhering the cut out photograph on a transparent film, printing the front side of this film on a positive film to produce a halftone positive film, printing the backside of said film on a negative film to produce a silhouette film in which the cut out portion appears as deep-black, superposing the halftone positive film on a photosensitive resin plate to produce a photographic resin plate, turning the silhouette film upside down and superposing it on the photosensitive resin plate and exposing it to light to produce a silhouette resin plate, alternately bringing the photographic resin plate and silhouette resin plate into contact with a continuous foaming resin plate.
