Letterpress Printing
Letterpress is the oldest form of printing; it is the method we have is mind when we speak of the invention of printing by Johannes Gutenberg more than 500 years ago. Printing and letterpress were synonymous until a relatively short time ago because letterpress was, and still is, the only reproduction method capable of using metallic types in the press. Metallic types on their part were historically the exclusive means for printing of reading matter. This condition remained unchanged for more than 200 years. It was first modified in the eighteenth century by the invention of stereotyping. Stereotypes made it possible to replace individual types for presswork with cast metal plates made from the original composition. The invention of electrotyping, made in the nineteenth century, added a second kind of duplicate plates and made it possible to free letterpress further from the limitations imposed on press construction and presswork by composition consisting of metallic types. But in spite of duplicate plates and composing machines, which were developed in the last third of the nineteenth century, metallic type remained the only means for converting reading matter into standardized letter forms. The next big step ahead was made after World War II when non – metallic composition became possible.
The exclusive ability of letterpress to print directly from metallic types distinguished letterpress for hundreds of years from other printing methods. Even at present this ability can make letterpress a most economical printing method for jobs consisting mainly of reading matter, particularly when it is possible to print the whole job directly from type.
Letterpress is especially well represented in job – and commercial printing. This is the name for printing as a service business. At this point it must be mentioned that many printed products can be produced by several printing methods. The zone of interchangeability of printing processes and methods is growing: consequently, we may find the same product listed as examples for the use of more than a single printing process or method.
Letterpress is the traditional method for the printing of books: it serves for the production of most magazines, many in relatively small editions, but some of an enormous circulation. Other products produced by letterpress include advertising materials; envelopes and calling cards, catalogs of various kinds; labels, business forms; tickets and many other items. As mentioned before, most of these products are not necessarily printed in letterpress but can also be produced by other printing methods.
One of the reasons for the great popularity of the letterpress method lies in its ability to produce printing in almost any required quantity with economy and dispatch.
