5. After you have produced a master fiche
with varying densities, the next step is to
duplicate that data at the duplicator
exposure setting which you determined
yielded the proper background density.
Make three copies, use the second, and
observe it in a viewer starting with the lowest
exposure. Look for the Komstar setting which
yields the brightest and most defined
character. If necessary, make paper prints to
determine optimum settings.
6. Once the Komstar data and forms intensity
settings are determined, produce a master
and duplicate fiche at those settings for
future reference.
After-Processing Information
Handling
As with all photographic products, exercise care
to avoid scratches, abrasions, and fingerprints.
It is recommended that camera originals be
handled as little as possible and with lint-free
nylon or cotton gloves.
Print-up
Because this is a heat-processed film with
incorporated developers, extreme heat or an
intense light source (i.e., readers and printers),
can cause further development of the
background area. Darkening of the background
is called print-up. Print-up is cosmetic in nature
and does not duplicate onto the second
generation copy. Kodak Imagelink DL 1000
Microfilm has properties which reduce print-up.
Viewing and Printing
Readers and viewers are a source of heat and
light at the film plane and can possibly cause
print-up. A reader whose gate temperature does
not exceed 65°C (150°F)* will, even after the
film has been viewed for several hours, maintain
sharp and easily read images. Readers and
viewers can be a source of scratches and
abrasions. For these reasons, it is recommended
that, whenever possible, only test fiche be used
in a reader.
*If the heat at the film plane is kept at 65°C (150°F) or lower
when measured as specified in ANSI/NAPM IT9.19-1994,
this print-up has no practical effect when viewing on a
reader or in making duplicates on a printer.
Keeping (Life Expectancy)
For optimum storage life, store processed film
in the dark at 70°F (21°C), 50% relative humidity
or below, with other conditions as specified in
American National Standard ANSI/NAPM
IT9.11-1993, Imaging MediaProcessed Safety
Photographic FilmsStorage. The useful life of
Kodak Imagelink DL 1000 Microfilm can only be
estimated from incubation tests at accelerated
conditions, since the film has not been
manufactured long enough to have experienced
practical losses of the image. Extrapolation of
high temperature keeping behavior to room
temperature storage is always subject to some
uncertainties. On the basis of work done at
Eastman Kodak Company and by the ANSI/
NAPM IT9-4 subcommittee, this film is estimated
to maintain a usable image for at least 100 years
when processed as recommended, and handled
and stored as described in ANSI/NAPM IT9.11-
1993. Storage at low temperature provides
greater assurance of satisfactory image stability.
