An Additive, High-Speed, Step-Reduction Printer

Abstract

An additive printer for higher production rate of reduction printing of 16mm from 35mm negatives has scene-to-scene color correction, density modulation and a steadier print with increased sharpness. It is readily convertible to a blow-up mode from 16mm negative to 35mm positive; film movements are of the registration pin type. Printing is done at 120 ft/min on the 35mm side, with the capability of going faster; negatives of various shrinkages can be accommodated. The machine has a multiple-length selective-fade shutter which is tape-controlled, and provides A & B printing capability, with intermixed lengths of fades and/or dissolves. A number of features provide simpler operation and greater safety measures, such as air-actuated trips which automatically stop the machine in the event of a film break, separate drive or synchronized drive for the negative and positive heads, built-in air-vacuum squeegees on both negative and positive films and multiple-speed selection.
