It is then exposed under the negative in a printing frame as soon as possible after sensitization, as its photosensitive properties do not last long. Exposure may last between several minutes and approximately one hour, depending on the brightness. The image is formed by a very fine orange-brown silver grain. At this point, it is generally toned, usually in a bath of gold chloride, which imbues it with colder tones, from reddish-brown to black depending on the precise composition of the gold bath. This operation dramatically improves preservation of the print, by reducing its chemical sensitivity. The toned proof is then fixed in a bath of sodium thiosulphate. Due to the delicate nature of the paper, in order to prevent crinkling or curling, in the majority of cases, the prints produced are mounted on a card backing sheet.
