Non-Silver Duplicating Films
Overview
Non Silver Duplicating Films
Imagelink Diazo C Microfilm 1957, 2957, 3957
Imagelink Diazo C Microfilm is a fast-speed, non-silver print film. Use it to generate direct-duplicating copies in fiche or roll form, from silver or reprintable diazo films. Other typical uses include producing negative-appearing copies from negative appearing computer-output microfilm originals and duplicating copies of source documents, engineering drawings, and continuous-tone negatives. Imagelink Diazo C Microfilm is formulated to produce a blue-dye image offering high visual contrast on a reader.
Imagelink Diazo D Microfilm 1956, 2956, 3956
Imagelink Diazo D Microfilm is formulated to produce a neutral-black background. The dyes offer high visual contrast for viewing and next-generation prints.
Imagelink Thermal Print Film KF 1353/2353
Imagelink Thermal Print Films are suitable for generating distribution copies (usually negative-appearing) in fiche or roll format i.e. clear lines with dark background made from positive-appearing, computer output microfilms (COM) or other camera original films. Reversed-polarity prints can also be made from other microfilm images. A title stripe, if used, facilitates fiche identification.

Specifications
Nominal Thickness Data (mils)
- 2462, 2468, and 2470: 4.0 mils Estar base (4.2 mils total, unprocessed)
- 3468: 2.5 mils Estar base (2.7 mils total, unprocessed)
Exposure
The following data indicates meter setting values for 1/25 second tungsten exposures calculated using the formula 45/H, where H is the exposure in lux-seconds required for a density of .20 (1.20 for x462 Microfilms) above minimum density with indicated processing. This number can be used directly with incident-light meters.
- x462: 2.1
- x468: 0.2
- 2470: 0.12
