<p>A method of rapidly treating an ultrahigh-contrast negative photographic material used in a photomechanical process excellent in the reproduction of originals composed of characters or dots. The above material containing a development inhibitor-releasing redox compound is treated first with a developer containing a phenol having an acid dissociation constant of 1x10-11 to 3x10-13 and then with an acidic hardening fixer containing a water-soluble aluminum compound. This method is particularly suited for treating stably and rapidly a photographic material for roomlight contact printing.</p> |
