Recent Laboratory Studies of Optical Reduction Printing

R. O. Drew, L. T. Sachtleben

This paper reports recent laboratory work which has resulted in marked improvements over previous 16-mm reduction print quality. Improvements in image quality accrue from exposure of the print with ultraviolet light and from the use of reflection reducing coatings on the lens surfaces, while speed variations are reduced by increasing printer speed up to as much as twice normal film speed. These improvements involve only relatively simple changes in commercial reduction printers.
