NEW METHODS OF PRINTING AND REPRODUCING SCHOLARLY MATERIALS.

This article presents information about new methods of printing and reproducing scholarly materials. Three lines of development are being pursued: composing typewriters producing positive images on paper; film composing machines based on standard matrix assemblies; and film composing machines based on non-standard matrix assemblies. The development of composing typewriters is characterized by two forces, to do something as cheaply as possible and to do it as much like metal types as possible. Major developments in printing machinery can be grouped under two heads, faster and more automatic printing equipment, and refinements in offset.
