In general

FOMATONER INDIGO is a liquid concentrate of an one-bath toner for the toning of black-and-white photographs into blue tone. The intensity of the image tone depends on diluting ratio, temperature and toning time. The toning takes place at room temperatures (20 – 25 oC). Photographs both on resin-coated (RC) paper base (e.g. Fomaspeed) and baryta paper base (e.g. Fomabrom) can be toned.

FOMATONER INDIGO is suitable for the toning of both new photographs (the toning takes place immediately after processing) and older ones.

Packaging

FOMATONER INDIGO is available as a two-component liquid concentrate (part A and part B) in a set containing 2 bottles of 250 ml.

Yield

The toning solution made from one set is sufficient to tone approx. 2 sq. m of paper irrespective of sort of the paper base which corresponds to approx. 45 photographs sized 18×24 cm. The yield depends on the optical density of photographs toned.
