Toning Black-and-White Materials

Photographic print toners are chemical solutions used to treat black-and-white prints after processing. What does treatment with a toner solution do to a black-and-white print?

Changes or enhances the image color to convey a mood or impression, from subtle to extraordinary.

Extends the life of the print image during display or storage. Toning converts the black-and-white silver image to an inert compound, which reduces the harmful effects of intense light, ultraviolet radiation, oxidizing gases, extremes of temperature and humidity, and fumes. All Kodak toners will protect the image whether or not they produce a color shift.

Enhances the maximum density (D-max) in the image. With some toners, you can increase the shadow densities in prints with little or no change in the image tone. For example, you can treat KODAK PROFESSIONAL POLYMAX Fine-Art Paper (discontinued) in KODAK PROFESSIONAL Rapid Selenium Toner to produce a richer range of tones in the shadow areas. The curve below shows the increase in upper-scale contrast and D-max of KODAK PROFESSIONAL POLYMAX Fine-Art Paper toned in Rapid Selenium Toner (diluted 1:40).

SELECTING A KODAK PROFESSIONAL PACKAGED TONER

The visual effect of a toner depends on a combination of factors:

the toner and toner dilution

the paper emulsion type, surface, and stock tint

the length of the toner treatment

the processing of the paper

Not all toners perform the same way with all papers. Be sure to select a compatible paper/toner combination. See the tables Tones Produced by Paper/Toner Combinations and Degree of Toning Produced by Paper/Toner Combinations.
