KODAK COM DR Microfilm 2467 / ESTAR Base
Features
Description
• Manufactured to meet ISO and ANSI
standards for an LE 500 film
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.
• Excellent capture of CRT, formsflash,
and cutmark
Minimum adjustments are necessary to
balance these exposures.
ProductApplications
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.
• 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
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
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.

Development Time and Transport Speed
These are starting-point recommendations
for deep-tank processors. Shallow-tank and
medium-tank processors, or variable operating
conditions in all processors, may require
replenishment rate adjustments to maintain
process activity levels.
Development/transport times should be set by
timing film speed (splice point) top of rack, roller-
to-roller while running in the processor. Transport
speeds are based on actual dwell times and
photographic aims, and are determined by timing
film speed, top of rack, entrance roller to exit
roller while running in the processor.

Replenishment Rates
Developer Film Path:
Once development time and transport rates
are set to acquire desired photographic aims,
replenishment rate settings are determined by
multiplying the transport speed by the required
replenishment rates for the appropriate film width
being used. Replenishment may be reduced if
significant quantities of leader are used. For
instance, with Kodak COM Professional
Developer and Replenisher DRC, practical
experience indicates rates as low as 7.5 mL/ft
of 105 mm film are adequate in deep tank
processors. The use of control charts such
as Kodak Publication A-1631 is recommended
for monitoring control.

The MTF curve was determined using a method
similar to that described in ANSI PH2.39-1977
(R1990).
The above chart can be used to determine
other development time/temperature
combinations that provide equivalent
photographic quality. Temperatures between
90 and 100°F (32 and 37.8°C) are optimum
for total system performance.
Notice: While the data presented are typical of production coatings, they do not represent standards which must be met by
Eastman Kodak Company. Varying storage, exposure, and processing conditions will affect results. The company reserves
the right to change and improve the product characteristics at any time.
After-ProcessInformation
Keeping
This film is suitable for archival keeping when processed as recommended. However, due to possible
variations in conditions, it is recommended that users establish their own compliance with existing
archival-keeping requirements as outlined in pertinent standard ANSI/NAPM IT9.1-1996, ISO 10602 -
1995, and in Kodak Booklet D-31. This film is within thiosulfate limits for microfilm, when processed
according to manufacturer’s recommendations.
