KODAK IMAGELINK DL 1000 Microfilm / 2482
Description
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).
Product Applications
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.
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.

Handling
Film not in cartridges should be handled in total darkness. Unexposed film in its cartridge can be handled in room light.
Storage
Store unopened packages of film at 21°C (70°F). If storage for longer than three months is needed, 13°C (55°F) or lower is recommended. Keep the film at 50% relative humidity or below, and protected from radiation and X-rays. To avoid moisture condensation on the film, cold or frozen film should be warmed throughout to approximate room temperature before the package is opened, six hours if refrigerated, or overnight if frozen. Once a package is opened, do not refrigerate or freeze the film. If the Kodak Komstar Microimage Processor will be shut down for four hours or more, unthread the film from the film transport.

Photographic Properties
The following data are based on development in the Kodak Komstar Microimage Processor as recommended.
Exposure
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.
The optimum exposure intensity setting is determined by selecting from a complete intensity series produced according to procedures as indicated under Exposure Optimization below.
 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.
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.
Depending on the Komstar being used, this can be done in several ways.
Kodak Optistar Image Writer
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.
Komstar 100/200/300 Microimage Processors, Komstar Microimage Processor IV, and Optistar Processor V
Spectral Sensitivity
Optimum sensitizing for helium-neon lasers (633 nm).
Exposure Optimization
To determine the proper COM and duplicator exposure settings, perform the following procedure:
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.
D-453
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.
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 MediaProcessed Safety
Photographic FilmsStorage. 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. The recent specifications for Thermally
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.
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.
NOTE: Refer to the latest revision of each
ANSI or ISO Standard specified.
*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.
