For Table Top Processors*

Mix the brown toner solution at a dilution of 1:25 (1 part brown toner to 25 parts water). The temperature of the brown toner solution should be 1000F. If the machine speed varies, adjust it to allow for a minimum of 25 seconds of dwell time in the brown toner solution.

As an example, the tank setup for a Kodak Prostar Processor is the following:

Tank Solution

1Brown Toner

2Brown Toner

3Brown Toner

4Brown Toner

5Wash

6Wash

For this particular application, a constant machine speed of 10 feet/min yields a dwell time in the brown toner solution (all four tanks) of 24-25 seconds.

*These are starting point recommendations. Final conditions will vary.

Procedure to Ensure Post-Processing Brown Toning

To ensure that the brown toner solution has changed the processed silver to silver sulfide, follow this procedure.

After the post-process brown toner treatment has been completed, measure the background density (or D-max) of an image of a plain white document on the microfilm. Bleach a portion of the microfilm that contains the filmed white documents with dichromate bleach, wash thoroughly, and dry the microfilm. Re-measure the background density (or D-max) of the white document. If 65% or more of the density remains, the brown toning is sufficient. This procedure is outlined in ANSI/NAPM IT9.15- 1993.5

Dichromate bleach is available by ordering the following from Solutek (1-617-445-5335):

Conclusion

Kodak Brown Toner, using the procedures described above, has been shown to meet ANSI specifications for satisfactorily toned film as described in ANSI/NAPM IT 9.15-1993.5All films toned at the Kodak Disaster Recovery Laboratory will be done in accordance with these procedures and standards. ANSI/NAPM IT 9.1-1996 (ANSI/ISO 10602-1995)6recognizes that microfilms given stabilizing treatments as described here are expected to achieve their full Life Expectancy (LE) of 500 years for polyester-based and 100 years for acetate-based films. If you have questions about brown toning, please call your local Kodak Representative or the Kodak Disaster Recovery Laboratory at 1-800-EKC-TEST (1-800-352-8378) or 716-253-3907.
