Handling and Projecting 35mm Archive and Studio Prints: Voluntary Guidelines
The continued availability of older American films for public exhibition depends on proper care of existing 35mm prints. Archive and studio prints (sometimes known as vault prints), unlike distribution copies, are produced in small quantities for internal use. Often a title is represented by a single 35mm print made from preservation materials or surviving from the original year of release. Additional copies can be difficult and expensive to make. Thus archives and studios lend only to exhibitors willing to take special care in handling and projecting these fragile materials.
The Public Access and Educational Use Task Force, appointed by the Librarian of Congress to ac/ise on the national film preservation program, has developed the following voluntary guidelines to assist exhibitors, archives and studios in framing acceptable practices for handling and projecting rare 35mm archive and studio prints. These voluntary guidelines draw upon the experience of archive and studio projectionists. They are presented as an informal reminder list for the practicing projectionist.
Preparing Projection Equipment for Use
1. Inspect equipment for dirt and dust, particularly at all contact points along the film path and at any optical or magnetic scanning points.
2. Check the mechanical alignment to insure that the film runs through the projector in a straight path and is not skewed.
3. Check film tension. Under normal operating conditions film tension should be between 6 and 16 ounce-feet (oz-ft). Because film and sprocket tooth combinations tear when the tension exceeds the uppermost limit of 15 pound feet (Ib-ft), the tension of all film handling equipment should be far below this level. Tension as low as 6 02-ft is sufficient to provide a steady screen image. Tension greater than 16 oz-ft accelerates film wear.
