DESCRIPTION

KODAK PROFESSIONAL B/W Duplicating Film SO-132 is an orthochromatic, medium-contrast film designed for one-step duplication of continuous-tone black-and-white negatives. This film does not require reversal processing. You can use it to duplicate images on bulky or fragile photographic plates or films. For long-term keeping, treat duplicates on this film with KODAK Rapid Selenium or KODAK Brown Toner.

STORAGE AND HANDLING

Store unexposed film at 55°F (13°C) or lower in the original sealed package. Always store film (exposed or unexposed) in a cool, dry place. To avoid moisture condensation on film that has been refrigerated, allow the film to warm up to room temperature before opening the package. Process film as soon as possible after exposure.

Protect processed film from strong light, and store it in a cool, dry place. For more information on storing duplicates, see KODAK Publication No. E-30, Storage and Care of Photographic Materials--Before and After Processing.

EXPOSURE

You can use tungsten, fluorescent, or tungsten-halogen light sources to expose this film. Make a series of test exposures under your conditions. Start with a trial exposure of 40 seconds if you use a tungsten light source that provides 5 footcandles (54 lux) at the exposure plane. More exposure produces lower densities in the duplicate; less exposure produces higher densities.

DARKROOM RECOMMENDATIONS

Use a KODAK 1A Safelight Filter (light red) in a suitable safelight lamp with a 15-watt bulb. Keep the safelight at least 4 feet (1.2  metres) from the film.

Note: In most exposure and processing systems, this film will require 2/3 to 1 stop more exposure than KODAK PROFESSIONAL B/W Duplicating Film SO-339.

MANUAL PROCESSING

The development times in the tables below are starting-point recommendations. To produce the required contrast in the duplicate, you can vary the development time. Likewise, you may need to adjust the exposure time to make the best duplicate.

Tray Processing

Provide continuous agitation.

Large-Tank Processing

Agitate once per minute.

Final Steps in Processing--
65 to 75°F (18 to 24°C)

MACHINE PROCESSING

You can process this film in roller-transport processors, such as the KODAK VERSAMAT Film Processor, Model 5, 11, or 411, with KODAK DURAFLO RT Developer Replenisher, KODAK DURAFLO Developer Starter, and KODAK Rapid Fixer.

The recommended machine speeds for processing this film at 80°F (26.5°C) are as follows:

TONING

For long-term keeping, you can treat duplicates produced on this film with KODAK Rapid Selenium Toner (diluted 1:29) or KODAK Brown Toner (diluted 1:32).

The capacity of either of these toners, without replenishment, is 150 sheets of 8 x 10-inch film (600 sheets of 4 x 5-inch film) per gallon of working solution.

Process the film as described in the Processing sections above. If the film has dried, presoak it before toning for several minutes in 65 to 75°F (18 to 24°C) water.

IMAGE-STRUCTURE CHARACTERISTICS

The data in this section is based on development in a KODAK VERSAMAT Film Processor, Model 5, at 80°F (26.5°C) in KODAK DURAFLO RT Developer Replenisher with two developer racks at 4.25 ft/min.

Characteristic Curves

Note: If you want to make prints at 5X or greater magnification from the duplicate negatives, first make a test duplicate negative and enlargement to be sure the image quality will be satisfactory for your application.
