Imaging materials — Wet-processed silver-gelatin type black-and-white phototgraphic reflection prints — Specifications for dark storage

ISO 18929:2003 establishes the specifications for silver-gelatine photographic reflection prints intended for dark storage and covers silver-gelatine print types of all weights.

ISO 18929:2003 applies to wet-processed black-and-white silver-gelatine photographic prints; including those that have been chemically treated (with a gold, selenium, sulfur or other chemical treatment bath) to improve the permanence of the silver image. It also applies to silver-gelatine prints processed by a monobath, which includes thiosulfate as a fixing agent followed by a conventional wash.
