paper saved by typesetting can amount to 30 to 50 per cent, which is significant if you are
considering running 1,000 copies of a 20-page booklet. Figure 7.7 shows various type styles.

Notes The typefaces used in this book hold your attention and have better readability,
resulting in better comprehension of the content, than would a typed book.
Typesetting should be used for forms, manuals, catalogues, and internal reports, as well as for
letters and announcements that require more than ordinary type faces.
In phototypesetting, a photographic technique is used to set the type; the phototypesetting
machine takes pictures of each character one at a time and then prints them at high speeds onto
photosensitive paper. Before the development of the phototypesetting machine, composer
typewriters were used to prepare special copy. The new phototypesetters are referred to as
photocomposers because they combine photographic typesetting capabilities with text-editing
capabilities. Photocomposition has, in fact, provided the ultimate link between the word
processing department and the printing department, creating an integrated information/word
processing operation that provides more services than correspondence-only word processing
centres. Photocomposition allows the typist to edit copy and insert typesetting programming
commands such as size and style of type, spacing, and alignment (such as number of columns,
right or left margin justification, or centred) — all on one machine.

A multitude of input possibilities are available with sophisticated word processing systems that
include photocomposition facilities. Depending on the individual machine, photocomposition
equipment can accept input from diverse keyboards in the form of paper tape readers, optical
character readers (OCR), and computer mag tapes. Various typewriters can be connected to
photocomposition equipment, and the machines can communicate with each other over long
distances.
