DESCRIPTION

EASTMAN Fine Grain Release Positive Film 5302 (35 mm)
and 7302 (16 mm) is a low-speed, high-resolutionprintfilm.
This blue-sensitive black-and-white film is designed for
general release printing. It is also useful for making both
positive and negative titles, and dubbing prints for sound.

BASE

This film has a clear acetate safety base with anti-static
protection, and a base thickness of 5.6 mils. In addition,
7302 Film has an anti-curl layer applied to the base.

DARKROOM RECOMMENDATIONS

Use a KODAK OA Safelight Filter / greenish yellow, with a
15-watt bulb, no closer to the film than 1.2 metres (4 feet).

STORAGE

Store unexposed film at 13˚C (55˚F) or lower. For extended
storage, store at -18˚C (0˚F) or below. Process exposed film
promptly. Store processed film according to the
recommendations in NAPM IT9.11-1992: for medium-term
storage (minimum of ten years), store at 25˚C (77˚F) or
lower at a relative humidity of 20 to 50 percent; for
extended-term storage (for preservation of material having
permanent value), store at 21˚C (77˚F) or lower at a relative
humidity of 20 to 50 percent; for extended-term storage (for
preservation of material having permanent value), store at
21˚C (70˚F) or lower at a relative humidity of 20 to 30
percent. For active use, store at 25˚C (77˚F) or lower at a
relative humidity of 50 ± 5 percent. Thisrelates to optimized
filmhandlingratherthanpreservation;static, dust-attraction,
and curl-related problems are generally minimized at the
higher relative humidity. After usage, the film should be
returned to the appropriate medium- or long-term storage
conditions as soon as possible.

For more information about medium- and long-term
storage, see NAPM IT9.11-1992, andKODAK Publications
H-1, KODAK Motion Picture Film, and
H-23, The Book of Film Care.

PRINTING CONDITIONS

You can make satisfactory prints using negatives of average
density if run on a continuous additive printer(such as aBell
& Howell Model C) at 180 feet per minute, equipped with a
1000-watt lamp at 80 volts dc (85 volts for 35 mm) and a
ground glass in the beam. Typical starting-point printer
settings are as follows:

Trim Setting Tape Setting

Beam 16 mm 35 mm 16 mm 35 mm

Red 17 21 32 24
Green 17 21 32 24
Blue 17 21 32 24

For laboratories with subtractive printers, such as a
Bell & Howell Model J, use the following starting-point
recommendations for 16 mm film: 1000-watt lamp at
55 volts dc and a printer speed of 62 feet per minute. For
35 mm films with a Bell & Howell Model D Printer, use
these starting-point recommendations: 500-watt lamp at
75 volts dc and 90 feet per minute. For both 16 and 35 mm
setups, use a neutral density filter (such as the KODAK
WRATTEN NeutralDensityFilter,No. 96) with a density of

0.50 in the beam and a diaphragm setting of 13.

SOUND-TRACK PRINTING

A variable-area positive silver sound track can be printed on
5302 / 7302 Film from a negative sound record on
EASTMAN EXR Sound Recording Film 5378™ / 7378™.
The optimum variable-area sound-track density for the print
liesbetween 1.2and 1.4,measured visuallyfor both16 and
35 mm films. This print density is chosen to provide a good
compromise between signal-to-noise ratio and frequency
response. The densities of the sound-track negatives
requiredto produce optimal printdensities are determined by
using recognized cross-modulation test procedures.

PROCESSING

Use the following process recommendations as starting
points for a typical continuous-immersion processor using
formulas presented in KODAK Publication No. H-24.15,
Manual for Processing EASTMAN Motion Picture Films,
Module 15. The processing times may require modification
for a particular machine.

LUBRICATION

All films destined for projection require some lubrication to
prevent problems during early projection life. Edge waxing
with a paraffin wax solvent solution provides a simple,
inexpensive, and adequate lubrication for 35 and 70 mm
projection prints. For 8 and 16 mm prints, an overall
lubricant may be required.

§ Drying depends on many factors such as air temperature, relative
humidity (RH), volume, rate and distribution of the air flow, final
squeegeeing, etc. In a conventional convectional-type drying cabinet
with air at about 35˚F (95˚C) and 40- to 50-percent RH, drying will take
15 to 20 minutes. In an impingement-type drying cabinet, however, with
a higher temperature and lower RH, drying time is greatly reduced. WIth
either type of dryer, the film should be dry without tackiness
the way through. Upon cooling to room temperature after leaving the
dryer,the film should be at equilibrium with the room air atapproximately
50-percent RH.

IMAGE STRUCTURE

The modulation-transfer curves, the diffuse rms granularity,
and the resolving power data were generated from samples
of 5302 Film exposed with tungsten light and processed as
recommended in KODAK Developer D-97 at 21˚C (70˚F) to
the recommended control gamma. For more information on
image-structure characteristics, see KODAK Publication
No. H-1, KODAK Motion Picture Film.
