Describes dark storage conditions, storage facilities and procedures for the handling and inspection of reflection prints of all types and sizes.

This International Standard specifies dark storage conditions, storage facilities and procedures for the handling and inspection of reflection prints of all types and sizes. This International Standard is applicable to prints on the following opaque supports: fibre-base paper; RC (resin coated) paper; pigmented and other types of plastic supports, e.g. polyester, cellulose acetate; fabric, e.g. canvas, linen. This International Standard is applicable to the following processed black-and-white silver gelatine prints: wet-processed, including those that have been chemically treated to improve the permanence of the silver image and/or to modify its colour, e.g. with gold, selenium or sulphur formulations; diffusion transfer, e.g. Polaroid and Fuji Photo Film instant prints1; stabilization-processed (which contain the silver image as well as invisible, chemically stabilized silver halides). This International Standard is applicable to the following processed multicolour and monochrome colour photographic prints: chromogenic, washed and stabilized; silver dye bleach; dye transfer; diffusion transfer, e.g. Polaroid and Fuji Photo Film instant prints1), peel-apart or integral; pigmented gelatine, e.g. carbon, carbro. This International Standard is applicable to black-and-white and colour prints made with the following systems: thermal dye transfer (commonly referred to as dye sublimation); thermal wax transfer; electro-photographic; dye and pigmented ink jet; swellable and porous-coated media supports; diazo. Recommendations for storage of photographic films and storage of processed photographic plates are given in ISO18911 and ISO18918 respectively. This International Standard is applicable to medium-term and extended-term storage conditions, as defined in Clause3.
