Features & Benefits
Get exceptional high quality in your processing.
Auto-reversal COM films use environmentally friendly low replenishment rate standard process photochemicals. Imagelink COM DR Film 2467 and Imagelink Ecopos 305 feature clear bright headers, sharp characters and high visual contrast for wet roll-format COM output. They are specifically designed for CRT-technology imaging and typically require deep-tank processing.
These films are slow speed with direct reversing emulsion that is blue-green sensitive with high spectral sensitivity in the 430 to 550 nm range.
Imagelink COM DR Microfilm 2467 and Imagelink Ecopos 305 are designed for use in blue phosphorous CRT (cathode ray tube) type computer output microfilmers (COMs). These devices photograph data displayed electronically rather than from printed documents. The Imagelink COM Microfilms are "drop-in" compatible with roll film COM equipment such as DatagraphiX 4500, XR, 3M Beta COM; and graphic COMs such as the III Cal Comp. Imagelink COM DR Microfilm 2467 and Imagelink Ecopos 305 Microfilm require only conventional processing, and does NOT require the use of a "full reversal" processing system, which uses dichromate bleach.
Drop in capability with low printing density and anti-static backing.
Features and Benefits
- Fast, efficient, high-quality duplication.
- Increased friendliness to the environment.
- Manufactured to meet ISO and ANSI standards for an LE 500 film.
- Excellent capture of CRT, formsflash, and cutmark. (Minimum adjustments are necessary to balance these exposures.)
- Uniform background provides crisp diazo copies.
- Low printing density (D-min 0.04-0.05). Clearer master characters (D-min) allow for higher throughput rates of duplicators.
- Good exposure and duplication latitude. The combination of a low D-min and medium contrast yields a wider exposure tolerance; also fewer tolerance, and fewer exposure adjustments of duplicator exposure times.
- Low process sensitivity. Even as process conditions vary, DR microfilm maintains high image quality.
- Invariant photographic speed. From batch to batch, there is no need to adjust exposure output. Halation protection. This eliminates "image bloom" caused by reflected light. Halation protection is particularly important with headers and detailed form slides.
- Process-surviving anti-static backing. Even after processing, static protection is maintained to reduce dirt and dust buildup during duplication and handling.
- Hardened emulsion for high-temperature rapid processing and resistance to abrasion
- Antihalation undercoat
- Meets ANSI and ISO standards for archival storage media
Nominal Thickness Data (Unprocessed)
- Support: 4.0 mils, Estar Base
- Total Film Thickness: 4.0 +/- 0.2 mils
- 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.
- Com-Pack Cartridge may be handled in room light.
- Roomlight Load may be handled in room light.
- Keep unprocessed film in the original, unopened package at 70 degrees Fahrenheit (21 degrees Celsius); 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, and five hours if frozen).
- Fine grain
- Excellent dimensional stability
- Medium contrast
- Excellent latent-image keeping
- High resolving power (resolving power based on recommended process)
- 1.6:1 (ISO-RP) - 100 line pairs/mm
- 1000:0 (ISO-RP) - 400 line pairs/mm
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
- Granularity: 6
Read at net diffuse visual density of 0.30 using a 48-micrometer aperature.
Processing Information: Processors and Processing Chemicals
- Imagelink COM DR 2467 and Imagelink Ecopos 305 Microfilm 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 Imagelink COM Professional Developer and Replenisher DRC with Imagelink Microfilm Fixer and Replenisher).
- Imagelink COM DR 2467 and Imagelink Ecopos 305 Microfilms are 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.
- D-max: 1.95 to 2.15. (When starting with fresh chemicals, D-max may be slightly lower than 1.95 until the chemicals are seasoned.)
- D-min: .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 startup of fresh developer may be slightly lower, but should stabilize in the 1.95 to 2.15 range.
