Product Applications
Description
Kodak Imagelink DL 1000 Microfilm is designed
to generate positive-appearing camera originals
in fiche format from helium-neon lasers used
in dry computer output microfilmers (COM)
equipment such as the Kodak Komstar 100/200/
300 Microimage Processors, Kodak Komstar
Microimage Processor IV, Kodak Optistar
Datawriter, Kodak Optistar V Processor,
Kodak Komstar Processor V, and the Kodak
Optistar Image Writer. This film can be handled
in room light and the equipment it is used with
does not require any special plumbing, venting,
or dark rooms.
Kodak Imagelink DL 1000 Microfilm 2482 is a
rapid-access, thermally processed (dry) silver
computer output microfilm. This film is designed
to be exposed by a red (helium neon) laser.
When developed, a positive appearing image is
formed (dark characters on a light background).
Kodak Imagelink DL 1000 Microfilm is an
extremely fine-grain, high-contrast microfilm
which offers the highest quality thermally
processed microimage available. When
DL 1000 is used with Kodak Premium 1000
Thermal Print Film 1323, a very high-quality
duplicate is achieved at optimum equipment
throughput speeds.
Imagelink DL 1000 Microfilm is primarily used to
make masters for generating negative-appearing
distribution copies (clear characters with dark
background) on thermal print film. Positive- or
negative-appearing copies can also be made on
diazo or silver films, depending on customer
preference. This film is not intended to be used
as the primary “working” copy or for frequent use
in reader printers.

Processing
1. Produce a processed BLANK master fiche
from the COM.
Kodak Komstar Microimage Processors contain
a heated metal drum which processes this film
at 1.8 meters (6 feet) per minute. Starting point
recommendations are 119 ± ½°C (246 ±1½°F)
for five (5) seconds.
2. Run an exposure series on the duplicator.
• Request 11 copies in the semiautomatic or
manual mode.
• Set the exposure to 1.0.
Duplicating Masters
• Using the fresh Kodak Imagelink DL 1000
fiche, start the copy cycle.
Print film density aims recommended when
printing from Kodak Imagelink DL 1000 Microfilm
/ 2482 Microfilm masters onto Kodak Premium
1000 Thermal Print Film 1323:
• After each exposure, increase the exposure
setting by 0.1.
• There should be 11 fiche produced, with
increasing background densities.

3. Using either a densitometer or the Kodak
Thermal Print Density Comparator, select
the fiche which has a density of 2.2 or
close to, but not darker than, the “Upper
Limit” patch on the Kodak Comparator.

This will become the background onto which
the Komstar characters will be printed.
See Kodak Publication D-49 for a description of
Kodak Thermal Print Films.
4. Produce an exposure series of Komstar
data onto Kodak Imagelink DL 1000
Microfilm such that it can be duplicated
onto a fiche with the proper background
density.
Photographic Properties
The following data are based on development in
the Kodak Komstar Microimage Processor as
recommended.
Depending on the Komstar being used, this
can be done in several ways.
Exposure
Kodak Optistar Image Writer
Kodak Imagelink DL 1000 Microfilm / 2482 is
exposed inside a computer output microfilmer
using a helium-neon laser for characters and
a tungsten light or helium-neon laser exposure
for the forms slide.
Note the current intensity settings.
Run either a test job or the “Quality Monitor
Test” from the Optistar Systems Console.
Run the job several times and vary the
intensity up or down (in increments of 10)
each time.
The optimum exposure intensity setting is
determined by selecting from a complete
intensity series produced according to
procedures as indicated under “Exposure
Optimization” below.
Komstar 100/200/300 Microimage
Processors, Komstar Microimage
Processor IV, and Optistar Processor V
Run either a test job or the “Quality Monitor
Test” from the Optistar Systems Console.
As the Komstar is running and starts a new
column of data (determined by either counting
frames or listening for the camera to change
directions), increase the “Data Intensity”
setting by one. This should produce a fiche
with eight columns of data at eight different
settings.

Exposure Optimization
To determine the proper COM and duplicator
exposure settings, perform the following

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.

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.
Processed Silver Microfilm—Specifications for
Stability are listed in ANSI/NAPM IT9.19-1994.
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.
NOTE: Refer to the latest revision of each
ANSI or ISO Standard specified.
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.

NOTE: These photographic modulation-transfer values were determined by using a method similar to the one described in
ANSI/NAPM PH2.39-1977(R1990) Photographic Modulation Transfer Function of Continuous-Tone Black-and-White
Photographic Films, Method of Measuring. The film was exposed with the specified illuminant to spatially varying
sinusoidal test patterns having an aerial image modulation of a nominal 35% at the image plane, with processing as
indicated. In most cases, the photographic modulation-transfer values are influenced by development-adjacency
effects and are not equivalent to the true optical modulation-transfer curve of the emulsion layer in the particular
photographic product.
