KODAK COM DR Microfilm 2467 / ESTAR Base

Description

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.

Product Applications

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.

Features

•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 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.
