Application of a Liquid Layer on Negative Films to Eliminate Surface Defects in Optical Printing

Raymond H. DeMoulin, Philip A. Ripson, Stanley L. Scudder

When 35mm color negative films are used repeatedly for release printing, they may become badly scratched. These scratched negatives give 16mm release prints of inferior quality in an optical reduction printing operation. The effects of scratches on the negative can be eliminated by applying a thin layer of liquid to the support side of the film just before printing. A Depue optical printer was modified by adding a roller applicator and liquid reservoir and by using an undercut pressure pad at the gate. This method is simpler and less expensive than liquid immersion printing and produces prints of high quality.
