Second-Generation Typesetter

A typesetter using a photomechanical technology, but which does not imitate a hot metal typesetter in its design. Second-generation typesetters are those which use rotating disks or film strips to carry master character images. Light is selectively flashed through the character image, focused through movable or interchangeable lenses, and received on photosensitive film or paper. Escapement is provided by means of a moving mirror that alters the light path, or by moving the film or the font matrix.
