KODAK Commercial Film

—Notice of Discontinuance—

Due to declining usage and demand, KODAK Commercial Film has been discontinued. Kodak Professional appreciates your loyalty to Commercial Film over the years. As a recommended alternative, we suggest KODAK PROFESSIONAL T-MAX 100 Film processed to a higher than normal contrast. Some experimentation with different development times will be necessary to adjust the contrast of the film to the level required by your particular application. Do not use a safelight with T-MAX 100 Film.

DESCRIPTION

KODAK Commercial Film is a medium-speed, blue-sensitive film with moderately high contrast. You can use it for copying continuous-tone originals when red and green sensitivity is unnecessary or unwanted. Because of its blue sensitivity, you can use a red safelight when you expose and process this film, which allows ease of use and development by inspection.

SIZES AVAILABLE

Sizes and catalog numbers may differ from country to country. For a complete list of sizes, contact a dealer who supplies Kodak Professional Products.

STORAGE AND HANDLING

Load and unload your camera in subdued light.

High temperatures or high humidity may produce unwanted quality changes. Store unexposed film at 24°C (75°F) or lower in the original package. Always store film (exposed or unexposed) in a cool, dry place. For best results, process film as soon as possible after exposur

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

EXPOSURE

Speed

Daylight: EI 50/18°
Tungsten or Quartz-Iodine: EI 8/10°
Pulsed-Xenon Arc: EI 12/12°

These exposure indexes are provided primarily as indicators of the relative speed of this film compared with other photographic materials. Use the exposure indexes for daylight, tungsten, or quartz-iodine illumination with exposure meters to establish trail exposures. The pulsed-xenon arc value indicates the relative speed of this film to pulsed-xenon illumination measured with a light integrator.

Exposure and Development Adjustments for Long and Short Exposures

At the exposure times in the table below, compensate for the reciprocity characteristics of this film by increasing exposure and adjusting the development as shown.

It may be difficult to use the table to estimate the adjusted times for calculated exposure times between 1 and 100 seconds. The graphs on the next page will help you find the adjusted times for calculated exposure times between those given in the table.

DARKROOM RECOMMENDATIONS

Use a KODAK 1 Safelight Filter (red) in a suitable safelight lamp with a 15-watt bulb. Keep the safelight at least 1.2 metres (4 feet) from the film. Run tests to determine that safelight use gives acceptable results for your application.

For information on safelight testing, see KODAK Publication K-4, How Safe Is Your Safelight?

PROCESSING

The development times in the table below are based on film used for copying or general applications at an exposure time of 1/25 second.

* With continuous agitation.
** With gaseous-burst agitation (1 second every 10 seconds) that provides pressure to raise the solution level 16 mm (5/8 inch). Development times shorter than 5 minutes may produce unsatisfactory uniformity.

The development times in the table below are based on film used for graphic arts applications.

*With continuous agitation

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

IMAGE-STRUCTURE CHARACTERISTICS

The data in this section is based on development at 20°C (68°F) in KODAK HC-110 Developer for 2 1/4 minutes.

Diffuse rms Granularity* 12

* Read at a net diffuse density of 1.0, using a 48-micrometre aperture, 12X magnification.
