The Bell & Howell Fully Automatic Sound Picture Production Printer

A. S. Howell, B. E. Stechbart, R. F. Mitchell

A new printer, in which the fundamental design is established on basic sensitometric specifications, is described. An analysis is presented of the requirements of the laboratory ideal of a printing machine, including such specifications as fully automatic fool-proof interlocking, elimination of operator's mistakes and film wastage, and many other features desirable in a machine of this type. The paper describes the new printer fully and shows how the printer can be set in practice to conform to absolute sensitometric standards.
