TECHNICAL DATA / BLACK-AND-WHITE FILM
K OD AK EKTA GRAPHIC HC Slide Film
December 2002 F-12
—NOTICE—
This film has been discontinued.
KODAK EKTAGRAPHIC HC Slide Film is a negative­working, orthochromatic film that is designed for making reverse-text black-and-white title slides (e.g., if your originals have black letters on a white background, they will reproduce as white letters on a black background). This film, features extremely high contrast, and wide exposure and development latitude—you get high contrast with opaque blacks and clear whites.
FEATURES BENEFITS
• Extremely high contrast • Opaque blacks and crisp
• Same emulsion and base as KODAK PROFESSIONAL KODALITH Ortho Film 6556, Type 3
whites for dramatic, legible titles
• Easy processing in KODAK PROFESSIONAL KOD ALITH Super RT Developer

STORAGE AND HANDLING
Store unexposed film at 75°F (24°C) 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 exposure.
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
T o f ind the best exposure for your copying equipment when first using this film, make a trial exposure series. Adjust the camera f-stop in exposures (3 above and 3 below your starting point). To determine the starting-point exposure time and aperture setting for the series, measure the illumination on the original material. T ake a direct reading with an incident-light meter, or read a gray card (18% reflectance side) on the copyboard with a reflected light meter. Set the exposure meter at Exposure Index (EI) 25 if the film will be developed in KODAK De veloper D-11, or EI 8 if developed in KOD AK PROFESSIONAL KODALITH Super RT Developer (see “Processing”).
To determine your first set of trial exposures, set the shutter speed at 1 second and make an exposure at every f-stop on the lens. Record the f-stop of the best exposure and note the lens and lighting arrangement; use these data as a starting point with other originals. After this initial test, bracket two stops on each side of the best exposure using
1
-stop increments; exposures will vary somewhat with the
3
width of the lines and the type size of the artwork.
Example: With four 200-watt tungsten lamps, two on each side of the original, and the shutter speed set at 1 second, the best exposure should be between f/5.6 and f/11. If you use two 200-watt lamps, one on each side of the original, the best exposure should be between f/4 and f/8.

DARKROOM RECOMMENDATIONS
Use a safelight equipped with a KODAK 1A Safelight Filter (light red) with a 15-watt bulb. Keep the safelight at least 4 feet (1.2 metres) 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
Small-Tank Processing (8- or 16-ounce tank)
Develop EKTAGRAPHIC HC Slide Film at 68°F (20°C) in a small tank. We recommend using KODAK Developer D-11 or KODAK PROFESSIONAL KODALITH Super RT Developer for processing this film. KOD AK Developer D-11 provides slightly lower contrast, more exposure latitude, longer solution life, and high projection contrast. It also produces faster film speed or short camera exposures.
Note: For even development of the entire roll, first fill the
tank with developer. Then, using the above safelight handling instructions, drop the loaded film reel into the developer and attach the top to the tank. Firmly tap the tank on the top of the work surface to dislodge any air bubbles. Agitate for 5 seconds every 30 seconds throughout development. You can do the remaining operation in room light.
