This International Standard establishes the specifications for silver-gelatin photographic reflection prints intended for dark storage. It covers silver-gelatin print types of all weights.<\/p>\n
This International Standard applies to wet-processed black-and-white silver-gelatin 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-gelatin prints processed by a monobath, which includes thiosulfate as a fixing agent followed by a conventional wash.<\/p>\n
This International Standard is not applicable to instant black-and-white photographic prints, stabilization-processed black-and-white prints (those where the undeveloped silver halide has been chemically converted and not removed), or thermally processed black-and-white prints. It does not apply to colour or dye-based photographic prints, nor to prints that have been processed by a monobath using other than a thiosulfate-type fixing solution, or prints where the silver salts are rendered more soluble by means other than thiosulfate.<\/p>\n
Laminated and adhesive mounted reflection prints, prints on poly (ethylene terephthalate) support, and prints that have been displayed are also excluded from this International Standard.<\/p>\n
