This paper describes some of the characteristics and applications of programs that have been developed recently in the author's laboratory, for the production of coded paper tapes to control the Photon photocomposing machine. Conventional typesetting machines have been supplemented in the last two decades by a variety of photocomposing machines that produce the original copy for photolithographic reproduction by a photographic process. In this process, images of letters and characters are focused by an optical system at appropriate positions of a roll of sensitized paper. A photocomposing machine contains a matrix of transparent characters in an opaque background, with a mechanism for illuminating one selected character at a time. Several types of photocomposing machines have been designed and manufactured. The work that is reported here has used some Photon machines that are installed in Boston, and which are equipped with paper tape readers.
