Metal type in the context of Typesetter

Printing emerged as early as the 4th millennium BCE in the form of cylinder seals used by the Proto-Elamite and Sumerian civilizations to certify documents written on clay tablets. Other early forms include block seals, hammered coinage, pottery imprints, and cloth printing. Initially a method of printing patterns on cloth such as silk, woodblock printing for texts on paper originated in Tang China by the 7th century, to the spread of book production and woodblock printing in other parts of Asia such as Korea and Japan. The Chinese Buddhist Diamond Sutra, printed by woodblock on 11 May 868, is the earliest known printed book with a precise publishing date. Movable type was invented in China during the 11th century by the Song dynasty artisan Bi Sheng, but it received limited use compared to woodblock printing. However, the use of copper movable types was documented in a Song-era book from 1193, and the earliest printed paper money using movable metal type to print the identifying codes were made in 1161. The technology also spread outside China, with the oldest extant printed book using metal movable type being the Jikji, printed in Korea in 1377 during the Goryeo era.

Woodblock printing was also used in Europe until the mid-15th century. Late medieval German inventor Johannes Gutenberg created the first printing press based on previously known mechanical presses and a process for mass-producing metal type. By the end of the 15th century, his invention and widescale circulation of the Gutenberg Bible became responsible for a burgeoning economical book publishing industry spreading globally across Renaissance Europe and eventually among the colonial publishers and printers that emerged in the British American colonies. This industry enabled the communication of ideas and the sharing of knowledge on an unprecedented scale, leading to the global spread of the printing press during the early modern period. Alongside the development of text printing, new and lower-cost methods of image reproduction were developed, including lithography, screen printing and photocopying.

In the manufacture of metal type used in letterpress printing, a matrix (from the Latin meaning womb or a female breeding animal) is the mould used to cast a letter, known as a sort. Matrices for printing types were made of copper.

However, in printmaking the matrix is whatever is used, with ink, to hold the image that makes up the print, whether a plate in etching and engraving or a woodblock in woodcut.

Typesetting is the composition of text for publication, display, or distribution by means of arranging physical type (or sort) in mechanical systems or glyphs in digital systems representing characters (letters and other symbols). Stored types are retrieved and ordered according to a language's orthography for visual display. Typesetting requires one or more fonts (which are widely but erroneously confused with and substituted for typefaces).

One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission.

The Linotype machine (/ˈlaɪnətaɪp/ LYNE-ə-type) is a "line casting" machine used in printing which is manufactured and sold by the former Mergenthaler Linotype Company and related companies. It was a hot metal typesetting system that cast lines of metal type. Linotype became one of the mainstays for typesetting, especially small-size body text for newspapers, magazines, and advertisements from the late 19th century to the 1970s and 1980s, when it was largely replaced by phototypesetting and then digital typesetting.

The name of the machine comes from producing an entire line of metal type at once, hence a line-o’-type. It was a significant improvement over the previous industry standard of letter-by-letter manual hand composition using a composing stick and shallow subdivided trays, called “cases”.

In letterpress printing, wood type is movable type made out of wood. First used in China for printing body text, wood type became popular during the nineteenth century for making large display typefaces for printing posters, because it was lighter and cheaper than large sizes of metal type.

Wood has been used since the earliest days of European printing for woodcut decorations and emblems, but it was not generally used for making typefaces due to the difficulty of reproducing the same shape many times for printing. In the 1820s, Darius Wells introduced mechanised wood type production using the powered router, and William Leavenworth in 1834 added a second major innovation of using a pantograph to cut a letter's shape from a pattern. This made it possible to mass-produce the same design in wood repeatedly. Wood type was manufactured and used worldwide in the nineteenth century for display use.

A type foundry is a company that designs or distributes typefaces. Before digital typography, type foundries manufactured and sold metal and wood typefaces for hand typesetting, and matrices for line-casting machines like the Linotype and Monotype, for letterpress printers. Today's digital type foundries accumulate and distribute typefaces (typically as digitized fonts) created by type designers, who may either be freelancers operating their own independent foundry, or employed by a foundry. Type foundries may also provide custom type design services.

Punchcutting is a craft used in traditional typography to cut letter punches in steel as the first stage of making metal type. Steel punches in the shape of the letter would be used to stamp matrices into copper, which were locked into a mould shape to cast type. Cutting punches and casting type was the first step of traditional typesetting. The cutting of letter punches was a highly skilled craft requiring much patience and practice. Often the designer of the type would not be personally involved in the cutting.

The initial design for type would be two-dimensional, but a punch has depth, and the three-dimensional shape of the punch, as well as factors such as the angle and depth to which it was driven into the matrix, would affect the appearance of the type on the page. The angle of the side of the punch was particularly significant.
