Abstract

Process for the production of photographic copies from photographic copy masters in a photographic copy apparatus, wherein initially in a measuring station of the photographic copy master an exposed photographic master material, on which photographic copy masters are exposed, is analyzed master by master. In the process, the measuring data necessary for the exposure of each master is determined, together with the size and the position of the center of each copy master on the film. A number is assigned unambiguously to each master, the number being determined by scanning an expanded DX code provided in periodic intervals in a border area of the master material by a single bar code detector used in the measuring station to read the expanded DX code. The number is determined by reading the expanded DX code. The numbers assigned to the copy masters, together with the associated measured data, are passed on to a computer and control unit. In an exposure station, located downstream from the measuring station in the direction of transport of the master material, the copy masters are exposed according to the measured data belonging to the prevailing copy master number present in the computer and control station onto photographic copy material to produce photographic copies. The number assigned to each copy master is applied to the photographic copy, preferably to the reverse side.
