NBS MONOGRAPH 99 Automatic Typographic-Quality Typesetting Techniques: A State-of-the-Art Review U.S. DEPARTMENT OF COMMERCE NATIONAL BUREAU OF STANDARDS —— THE NATIONAL BUREAU OF STANDARDS The National Bureau of Standards ' provides measurement and technical information services essential to the efficiency and effectiveness of the work of the Nation's scientists and engineers. The Bureau serves also as a focal point in the Federal Government for assuring maximum application of the physical and engineering sciences to the advancement of technology in industry- and commerce. To accomplish this mission, the Bureau is organized into three institutes covering broad program areas of research and services: THE INSTITUTE FOR BASIC STANDARDS . provides the central basis within the United States for a complete and consistent system of physical measurements, coordinates that system with the measurement systems of other nations, and furnishes essential services leading to accurate and uniform physical measurements throughout the Nation's scientific community, industry, and commerce. This Institute comprises a series of divisions, each serving a classical subject matter area: —Applied Mathematics—^Electricity—Metrology—Mechanics—-Heat—Atomic Physics Physical Chemistry—Radiation Physics—Laboratory Astrophysics ^—Radio Standards Laboratory,^ which includes Radio Standards Physics and Radio Standards Engineering- Office of Standard Reference Data. THE INSTITUTE FOR MATERIALS RESEARCH . conducts materials research and provides associated materials services including mainly reference materials and data on the properties of materials. Beyond its direct interest to the Nation's scientists and engineers, this Institute yields services which are essential to the advancement of technology in industry and commerce. This Institute is organized primarily by technical fields: —Analytical Chemistry—Metallurgy'—-Reactor Radiations—^Polymers—Inorganic Mate- rials—Cryogenics ^—Materials Evaluation Laboratory—Office of Standard Reference Materials. THE INSTITUTE FOR APPLIED TECHNOLOGY . provides technical services to promote the use of available technolog}' and to facilitate technological innovation in industry and government. The principal elements of this Institute are: —Building Research—Electronic Instrumentation—-Textile and Apparel Technology Center—Technical Analysis—Center for Computer Sciences and Technology—Office of Weights and Measures—^Office of Engineering Standards Services—Office of Invention and Innovation—Clearinghouse for Federal Scientific and Technical Information.^ ' Headquarters and Laboratories at Gaithersburg, Maryland, unless otherwise noted mailing Washing- ; address ton, D.C. 20234. 2 Located at Boulder, Colorado 80302. 3 Located at 5285 Port Roval Road, Springfield, Virginia 22151.

National Bureau of Standards Monograph 99 Issued April 7, 1967 For sale by the Superintendent of Documents, U.S. Government Printing Office Washington, D.C. 20402 - Price 70 cents Library of Congress Catalog Card No. 66-62198 Foreword The Research Information Center and Advisory Service on Information Processing, (RICASIP), which has been incorporated in the Technical Information Exchange, Center for Computer Sciences and Technology, National Bureau of Standards, has been engaged in a continuing program to collect information and maintain current awareness about research and development activities in the field of information processing and retrieval. An important responsibihty of RICASIP which has been jointly supported by the National Science Foundation and NBS, has been the preparation of state-of-the- art reviews on topics of current interest in various areas of this broad field. This report is one of a series intended as contributions toward improved interchange of information among those engaged in research and development in this field. The report considers new techniques for typographic-quality composition based upon ma- chine generation, manipulation, and processing of textual and other materials to be reproduced in multiple copies for distribution or publication. It should be noted that names and descriptions of specific proprietary devices and equipment have been included for the convenience of the reader, but completeness in this respect is recognized to be impossible. It is also to be noted that certain important developments have remained proprietary or have not been reported in the open Uterature. Some of the major contributors to key developments in the field may thus have been inadvertently omitted. The omission of any method or device does not necessarily imply that it is con- sidered unsuitable or unsatisfactory. Conversely, inclusion of descriptive material on any proprietary instrument, product, or process does not constitute endorsement. In general, we shall be concerned with the techniques that offer reproduction copy of typographic quality, which may be defined in terms of a variety of' factors involving human engineering, aesthetic, economic, and productivity considerations. It is to be noted that this report was prepared on the Linofilm equipment of the United States Government Printing Office. A. V. ASTIN, Director. Ill Contents Page Foreword ,. HI 1.
