Photo-Lithography

The manual presents the chemical principles and hands-on techniques for producing lithographic prints by photographic means, covering theory of lithography, characteristics of stones and metal plates, ink and sensitizing materials, transfer and etching procedures, and methods for corrections and reversing images. It describes preparation of litho stones, use of acids and gums, practical recipes and process sequences tested by the author, and adaptations for color plate production. Emphasis is on clear, practical instruction for technicians and printers rather than historical exposition, with step-by-step guidance intended to reproducibly convert photographs, drawings, and paintings into printable plates.
