Microfilming
guidelines

The following description provides you with a brief overview of some
basic microfilming techniques and principles. The descriptions are
aimed at the novice operator; however, even if you are a more
experienced operator you may find it helpful to review this information.

Microfilm
specifications

The microfilm used in the scanner must meet the following
specifications:

Width — 16 mm, unperforated.

Types — silver microfilms can be used to produce originals or duplicate
reels. However, duplicates from silver originals are more commonly
made using diazo microfilm (which provides direct duplicates of the
original), or vesicular/thermal microfilm (which provides reverse polarity
duplicates). Any microfilm selected must have a clear base. Tinted-base
microfilms cannot be used with the scanner. However, if tinted-base
originals are duplicated on clear base microfilms, the duplicate copies
can be used.

Film Leader — M-type film leader must be clear; black leader cannot be
used.

Thickness — 2.5 to 5.0 mils.

NOTE: Thermal films less than 4 mils thick can stretch during

processing and become narrower than 16 mm, which can
result in unreliable performance.
