Abstract
A protected photographic film structure includes a strip of photographic film comprised of a series of frames, an information carrier strip secured to the strip of photographic film and running alongside the strip of film and bearing information concerning the printing order and/or the customer giving the printing order, and a pair of flexible protective strips each secured to the information carrier strip along the length of the information carrier strip at a respective one of the two faces of the information carrier strip. Each protective strip extends in direction from the information carrier strip towards the strip of photographic film and overlies and thereby protects a respective one of the two faces of the strip of photographic film. When the film strip structure travels along a predetermined path through a printing installation a device bends back the protective strips upstream of the printing station so that the strip of photographic film passes through the printing station uncovered by the protective strips.
