In offset lithography, the design is printed upon a rubber blanket which in turn transmits the design to the paper. Practically all lithography is now of the offset type. While both coated and uncoated papers are being successfully used for lithographing purposes, the latter is chiefly used. Blanket resiliency makes it possible to secure excellent results in halftones on uncoated (rough) stock. Examples -- displays, posters, books, book covers, booklets, circulars, labels, wrapping papers, calendars, inserts, etc.

Slug Cast by a Typesetting Machine of the Line Type.

1. Type may also be set by composing or typesetting machines.

2. One of three types of machine is the intertype. It composes with matrices, small brass

dies, which have the forms of various characters indented in their sides. The individual matrices are assembled in the desired order for each line of the material, and a type-high metal slug with the letters in relief is cast in one piece from these matrices.

3. Another typesetting machine which operates on the same principle as the intertype is

the linotype.

4. Corrections in linotype and intertype matter are made by resetting the complete line

in which an error occurs.
