Abstract: In a photographic paper production method, a photographic paper support is coated with one or more photographic silver halide emulsion layers and one or more other hydrophilic colloid layers, at least one of the layers including a hardener. The coated support is then dried and conditioned to a temperature of from 24.degree. C. to 33.degree. C.
