Kodak Duplicating Microfilms
Kodak
Duplicating Microfilms are
silver-halide films designed for
making high quality duplicates of
original camera and other
duplicate microfilms. Depending
on the film type used, these films
can either maintain or reverse
image polarity. These duplicating
microfilms can be used in a
variety of manufacturer’s silver
duplicators.
Kodak
Duplicating
Microfilms are fine grain, high resolution microfilms with the exposure and
development latitude to duplicate/enhance varying quality originals.

Product applications
Eastman Kodak Company produces
Kodak
Duplicating 2462 Microfilm,
Kodak
Direct Duplicating 2468/3468 Microfilm and
Kodak
Direct Duplicating
Intermediate 2470 Microfilm. These films all require conventional processing.
Direct duplicating films maintain image polarity between generations.
Kodak
Duplicating 2462 Microfilm reverses polarity.
Kodak
Duplicating and
Direct Duplicating Microfilms
are primarily intended for
creating multiple distribution
copies of camera film
masters, and occasionally
as intermediate print film
masters, when creating
large quantities of duplicates
such that the original camera film is not at risk of damage.
Kodak
Direct
Duplicating Intermediate Microfilm is typically used as an intermediate print
master but may also be used as a distribution copy. All duplicating microfilms
use a “contact-printing” method, such that the master and duplicate are
brought into intimate contact during exposure. A description of each follows.
