EASTMAN Fine Grain Release
Positive Film 5302

/ 7302

DESCRIPTION
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 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. This relates to optimized
film handling ratherthan 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
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 a Bell
& 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:
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 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 5378™ / 7378™.
The optimum variable-area sound-track density for the print
liesbetween 1.2and1.4, measuredvisuallyfor 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
required toproduce optimal printdensities are determinedby
using recognized cross-modulation test procedures.
