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 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.

NOTE: Refer to the latest revision of each ANSI or ISO Standard specified.
