Silver Duplicating Microfilms

Overview

Silver Duplicating Films

IMAGELINK Pos Duplicating Microfilm (Estar Base)

IMAGELINK Pos 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 (Estar Base)
IMAGELINK LC Direct Duplicating Microfilm (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 Direct Duplicating film for your microfiche and roll-film applications; and LC Direct Duplicating 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)

  • IMAGELINK LC Direct Duplicating Microfilm: 4.0 mils Estar base (4.2 mils total, unprocessed)
  • IMAGELINK Pos Microfilm 10:  4.0 mils Estar base (4.2 mils total, unprocessed)
  • IMAGELINK Direct Duplicating Microfilm 10:  4.0 mils  (4.2 mils total, unprocessed)
  • IMAGELINK Direct Duplicating Film 06: 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 Pos Microfilms) above minimum density with indicated processing. This number can be used directly with incident-light meters.

  • Pos: 2.1
  • Direct Dupe: 0.2
  • LC: 0.12
