Composition from publisher-prepared, machine-readable input

Much of today´s CRT photocomposition is being processed through computer systems from typed OCR input or from magnetic tapes. Both approaches have some attraction for publishers who may have the capability of preparing such input within their own editorial offices, or from available computerized master files of data. Advantages of these procedures and some problems which have been encountered are discussed. The importance of personnel selection and training, attention to details of specifications, and equipment maintenance are emphasized. With careful programming, data files can frequently be converted into typesetting language, selecting and rearranging material to meet a publisher´s needs.
