An Application of Direct-Positive Sound Track in 16-MM Release Processing by Duplication Method

When dupe negatives are employed to make large releases on 16-mm positive, 3 successive printing operations are normally involved in arriving at the release print. That is, the master positive, dupe negative, and release print are made in order. Since each printing operation is attended by some degree of quality degeneration, it is desirable to reduce the operations to a minimum. — In the application described, the first printing is eliminated by rerecording to direct positive on 16-mm film. The amplifier channel feeding the direct-positive recorder is suitably equalized and compressed for 16-mm projection conditions, and bridges the channel used to make the normal rerecorded negative for 35-mm release. A 32-mm release negative is then made on a nonslip printer from the 16-mm direct positive.
