However, the photographic method of transferring an image from the copy to the plate

is usually used. The photographic film is placed in contact with a sensitized Multilith plate and the negative image is "burned into" the plate by exposure to light.

Chapter 51 METHODS OF PRINTING

THE three basic methods of printing are -- relief (raised surface), planographic (surface), and intaglio (subsurface).

In relief printing, also referred to as letterpress, the design is raised in relief from the surrounding surface and only the raised surface portions print after being inked. Examples -- newspapers, magazines, booklets, circulars printed from type, electrotypes, stereotypes, halftone plates, line cuts, etc. Relief printing is adaptable to all finishes of paper for type work. Where the screen is coarse enough it is adaptable on rough-surface papers, but the best results for halftone printing are obtained with a fine screen halftone on a coated paper surface.

California Job Case for Type.

1. In setting type by hand, individual letters of type are picked from a job case and

placed into a composing stick in which they are arranged and spaced as desired. Each line is removed as it is set and placed on a flat tray called a galley. When the page is complete, corrected, etc., it is locked up for the printing press. Simple corrections are made by removing the letter or whatever is in error and changing it.
