Before-Process Handling and Storage
Handling
Unprotected films should be handled in total
darkness or under safelight conditions such
as a Kodak No. 2 Safelight Filter / dark red,
or a Kodak No. 1 Safelight Filter / red, with
a 15-watt bulb at least four feet from the film.
However, the following package configurations
may be handled in room light:
• Com-Pack Cartridge
• Roomlight Load
Storage
For best storage, keep unprocessed film in
the original, unopened package at 70°F (21°C),
50% relative humidity or below, and protected
from radiation and X-rays. To avoid moisture
condensation on film that has been refrigerated,
do not open the package until the film has
warmed throughout to normal room temperature,
about three hours if refrigerated or five hours
if frozen.
Photographic Properties
• Fine grain
• Excellent dimensional stability
• Medium contrast
• Excellent latent-image keeping
• High resolving power
Resolving power: (based on recommended
process)
Note: Refer to the latest revision of each ANSI
or ISO Standard specified.
Test-Object Contrast Line Pairs/mm
1.6:1 (ISO-RP) 100
1000:1 (ISO-RP) 400
These values were determined by a method
similar to the one described in ISO Standard
6328-1982, “Photography - Photographic
Materials - Determination of ISO Resolving
Power,” except the light source used was a
high pressure mercury vapor arc.
Diffuse RMS Granularity: 6
Read at net diffuse visual density of 0.30 using
a 48-micrometre aperture. A more detailed
discussion of granularity can be found in
Kodak Publication F-20, “Understanding
Graininess and Granularity.”
Processing Information
Processors and Processing Chemicals
Kodak COM DR Microfilm 2467 can be
processed in most typical continuous-strand
type medium and deep-tank processors such
as Allen F10, F-10R, F-20, F-20R, Houston
Fearless 76, Oscar, Jamieson, Hollywood,
Kodak Versamat 75, and others utilizing
Kodak COM Professional Developer and
Replenisher DRC with Kodak Microfilm Fixer
and Replenisher. COM DR 2467 Microfilm is
compatible with all standard microfilm processing
equipment and high-quality microfilm chemicals,
although results may vary.
IMPORTANT: For best results and to avoid
aeration, always add chemical
concentrate to water, not water
to concentrate.
Photographic Aims
D-max:1.95 to 2.15*
D-min: 0.06 or lower
Processor transport speed and/or temperature
may be varied to achieve D-max and D-min
values. Process adjustments to achieve a D-max
in the range of 1.95 to 2.15 or lower D-min may
be required depending on unique processing
situations. Initial D-max on start-up of fresh
developer may be slightly lower, but should
stabilize in the 1.95 to 2.15 range.
* When starting with fresh chemicals, D-max may
be slightly lower than 1.95 until the chemicals
are seasoned.
