This paper describes the design and method of operation of an internal drum scanning system for transferring imagery from art work to a printing plate. Criteria for resolution, plate size, transfer rate, machine cycle time, and transmission efficiency are given. The major advantages of the internal drum scanning technique lie in simplicity of design and the flexibility to deal with a number of sizes of art and plate. Attendant to these design features are the prospects for low manufacturing cost. The potential for the use of such scanning systems for both input and output of automated photo composition systems is also discussed.
