Kodak COM DR Microfilm 2467 (Estar Base) is a
slow-speed film with a direct reversing emulsion
that is blue-green sensitive. It has high spectral
sensitivity in the 430 to 550 nm range.
Kodak COM DR Microfilm 2467 is 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. COM DR Microfilm is drop-in
compatible with roll film COM equipment
such as Bell & Howell, DatagraphiX 4500, XR,
3M Beta COM, and graphic COMs such as
the III Cal Comp. COM DR Microfilm requires
only conventional processing, and does not
require the use of a full reversal processing
system, which uses dichromate bleach.
Manufactured to meet ISO and ANSI
standards for an LE 500 film
Excellent capture of CRT, formsflash,
Minimum adjustments are necessary to
balance these exposures.
Uniform background provides crisp
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
and fewer exposure adjustments of duplicator
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 eliminates image
bloom caused by reflected light. This is
particularly important with headers and
detailed form slides.
Process-surviving antistatic backing
Even after processing, static protection is
maintained to reduce dirt and dust build-up
during duplication and handling.
