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.
