EASTMAN Fine Grain Release
Positive Film 5302 / 7302
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.
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:
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.
