EASTMAN Fine Grain Release
Positive Film 5302 / 7302
TECHNICAL DATA /
EASTMAN Fine Grain Release Positive Film 5302 (35 mm)
and 7302 (16 mm) is a low speed, high-resolution print
film. 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 for dubbing prints for
sound.
BLACK-AND-WHITE PRINT FILM
BASE
This film has a clear acetate safety base with an anti-static
protective layer. The base thickness is 5.6 mils. In addition,
7302 Film has an anti-curl layer applied to the base.
DARKROOM RECOMMENDATIONS
Use a KODAK OC 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 lower. 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 (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. This relates to optimized film handling rather than
preservation; 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, and KODAK Publications

PRINTER CONDITIONS
You can make satisfactory prints using negatives of
average density if run on a continuous additive printer
(such as the Bell & Howell Model C) run at 180 ft/min, and
equipped with a 1000-watt lamp operated at 80 volts (85
volts for 35 mm), and a ground glass in the beam. Typical
starting-point printer settings are as follows:
Beam
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 Printer, the following recommendations
should be helpful as a starting point: 1000-watt lamp at 55
volts and a printer speed of 62 feet per minute for 16 mm
film. For 35 mm film, using a Bell & Howell Model D
Printer: 500-watt lamp at 75 volts and 90 feet per minute.
For both 16 and 35 mm setups use a neutral density filter
(such as the KODAK WRATTEN Neutral Density Filter,
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 2378/3378. The
optimum variable-area sound track density for the print
lies between 1.2 and 1.4, measured visually for both 16 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
required to produce optimal print densities are determined
by using recognized cross-modulation test procedures.

Many factors affect the drying: air temperature, relative humidity (RH);
volume, rate and distribution of the air flow; final squeegeeing, etc. In a
conventional convection-type drying cabinet with air at about 95°F (35° C)
and 40 to 50 percent RH, drying will take 15 to 20 minutes. With 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 1/2 to 2/3 of the way through. Upon cooling
to room temperature after leaving the dryer, the film should be in equilibrium
with the room air at approximately 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
70 F (21 C) to the recommended control gamma. For more
information on image-structure characteristics, see

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.
