ABSTRACT:
By providing a photographic original plate on which an original picture image and a light-shielding mask are formed, two identical pictures can be formed by exposing a sheet of photosensitive material with the original plate placed thereon and repeating the procedure after rotating the original plate 180 degrees about a point which is located outside of the picture image and the light-shielding mask. Though the two printed images are inverted relative to each other, the final prints are eventually cut apart along a central line and no problem arises. Through adoption of the method and the use of the novel photographic original plate, not only the printing process becomes simpler than conventional method but a better result in the final prints can be obtained.
