Description
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 a family of 
duplicating films (2462, 4462), a family of direct 
duplicating microfilms (2468, 3468, 4468) and one 
direct duplicating intermediate microfilm (2470). They 
all require conventional processing. Direct duplicating 
films maintain image polarity between generations. 
Duplicating microfilm reverses polarity.
Kodak Duplicating, Direct Duplicating Microfilms and 
Positive Print 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. The 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.
