Type: A Primer of Information About the Mechanical Features of Printing Types / Their Sizes, Font Schemes, &c. with a Brief Description of Their Manufacture

This treatise is the first of a series of text-books, published under the general title of Typographic Technical Series for Apprentices , which have been prepared under the auspices of the Committee on Education of the United Typothetae of America, for the use of printers’ apprentices and students of typographic printing.
It is not what they are but what they can be made to do under the control of trained intelligence and skilful hands that makes printer’s types of importance to the world. No tools used in modern industry seem simpler than these little pieces of metal, yet they are the product of the most highly specialized skill and ingeniously perfected mechanisms. To the young printer their physical elements are matters of first concern. An understanding of these elements may be only a small part of his trade education, but it is important. The possibilities and the limitations of type can be appreciated only by thorough familiarity with the technical details and niceties provided by the modern typefounder.




Printing owes its development first and chiefly to movable metal types. The so-called invention of printing was the discovery of a method of making serviceable type in quantity. The idea of a separate type for each letter of the alphabet was probably conceived long before Gutenberg’s time, but it remained for him and his associates to devise an apparatus for making them quickly and accurately enough to be of practical value. That apparatus was the type mold, which experience has since proved to be the most efficient means of securing exactness and uniformity in a number of small pieces of metal.
Type is made of an alloy of lead, tin, and antimony. Its length (technically called height-to-paper) is .918 of an inch. Each type is cast separately in a mold, and has the letter or printing character in bold relief on one end.
Exact uniformity of body is necessary in order that the types, when composed in lines and pages, may be locked together by pressure at the sides so as to make a compact mass. All types in a printing form must be of the same height, so that their faces may present a uniformly level surface from which an impression may be made that will show all the characters clearly. A short type will print faintly or will not print at all, while a long one will be unduly forced into the sheet.
