| Heat vs. Tape |
| |
When your master film is stored in a vault, several reels are spooled together on large, thousand-foot reels and
stored in "pancake" canisters. There are two methods for splicing the tape ends together - tape or heat splicing. In
the past, many microfilm labs used common cellophane or even masking tape to splice these ends. Unfortunately, even
so-called "film tape" will begin to oxidize in just a few years, causing the onset of destructive redox.
Heritage Microfilm uses a heat splicer, which actually "welds" the ends together, using a precisely controlled heat element. This
eliminates the need for tape, and the resultant damage caused tape splicing. It takes longer, but it is the best method available.
Caution: If your microfilm vendor is using any type of tape to splice your master film, problems will arise, in most cases sooner
rather than later. Insist upon heat splicing for your precious history. |
