Overview
Silver Duplicating Films
Imagelink Duplicating Microfilm 2462 (Estar Base)
Imagelink Duplicating Microfilms are micro-fine grain, silver reverse image films used for making contact prints from camera microfilms and duplicate microfilms in microfiche and roll-film applications. Silver duplicating films have a life expectancy of 500 years (LE-500) when processed and stored properly.
Imagelink Direct Duplicating Microfilm 2468, 3468, (Estar Base), Direct Intermediate Microfilm 2470 (Estar Base)
Imagelink Direct Duplicating Microfilms are micro-fine grain, silver, direct-image films developed for making contact prints from camera microfilms and duplicate microfilms. Use 4468 film for your microfiche applications; 2468 and 3468 films for roll-film applications; and 2470 for making intermediate direct-image contact prints. Silver duplicating films have a life expectancy of 500 years (LE-500) when processed and stored properly.
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.
