ABSTRACT: The process described herein for reproducing plastic objects, which consists in preparing a photographic negative of the object to be produced in a light graduated in proportion to the prominence of the surface thereof, preparing the photographic negative of said object in a differently-distributed light, preparing a diapositive [positive transparency] of one of said negatives, copying the diapositive and the uncopied negative on a sensitized mass capable of producing a relief, and finally developing said mass to reproduce the form of the original. [Formal abstracts were not written for many older patents. Independent claim(s) substituted for abstract for this patent.]XX
