Electronic photocomposition system

摘要: An electronic photocomposition system forms patterns, including characters, on an imaging device, such as a cathode ray tube, and focuses the patterns onto photosensitive surface for recording thereon. The characters formed include ascender that ascend from predetermined character baseline descender descend below baseline. Each is by plurality of successive vertical scans create individual slices. start each scan positioned at displaced to bottommost portion character. retraced immediately upon traversing outer periphery during so length corresponds contour characters. are stepped across scanned and, end scanning character, jumped position where next begins with no intercharacter space being scanned.
