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

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.
KODAK Packaged Toners
KODAK PROFESSIONAL Rapid Selenium Toner.
Produces several cool chocolate-brown hues with warm-tone
papers, purplish brown tones with neutral-tone papers, and
very little or no change with cold-tone papers. Use the 1:20

and maximum density with a minimum tone change, use a
1:20 or 1:40 dilution. You can also use this toner with
black-and-white films. It converts the silver image to silver
selenide.
KODAK PROFESSIONAL Brown Toner. Produces a
