Paper Abstract

The Autologic Micro-5 CRT phototypesetter employs a vacuum-tensioned web transport wherein type images displayed on a cathode-ray tube are imaged by a lens upon photographic film or paper. A unique servo design utilizing a microcomputer permits character exposure while the media is in motion. An extensive evaluation of type requirements and photographic materials led to an optimized lens design that provides the necessary type acuity and machine speed at moderate cost. A family of optical magnifications are housed in a common lens barrel design, thus maximizing commonality. The Micro-5 can be used to typeset both characters and halftone pictures. It can produce complete camera-ready pages, eliminating traditional pasteup composition. Typefonts are stored digitally upon an integral magnetic disc, and displayed on the CRT utilizing a patented technique.
