Type case in the context of "Typesetting"

Typography is the art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line spacing, letter spacing, and spaces between pairs of letters. The term typography is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process. Type design is a closely related craft, sometimes considered part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers. Typography also may be used as an ornamental and decorative device, unrelated to the communication of information.

Typography is also the work of graphic designers, art directors, manga artists, comic book artists, and, now, anyone who arranges words, letters, numbers, and symbols for publication, display, or distribution, from clerical workers and newsletter writers to anyone self-publishing materials. Until the Digital Age, typography was a specialized occupation. Personal computers opened up typography to new generations of previously unrelated designers and lay users. As the capability to create typography has become ubiquitous, the application of principles and best practices developed over generations of skilled workers and professionals has diminished.

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 letterpress printing and typesetting, a composing stick is a tray-like tool used to assemble pieces of metal type into words and lines, which are then transferred to a galley before being locked into a forme and printed. Many composing sticks have one adjustable end, allowing the length of the lines and consequent width of the page or column to be set, with spaces and quadrats of different sizes being used to make up the exact width. Early composing sticks often had a fixed measure, as did many used in setting type for newspapers, which were fixed to the width of a standard column, when newspapers were still composed by hand.

The compositor takes the pieces of type from the boxes (compartments) of the type case and places them in the composing stick, working from left to right and placing the letters upside-down with the nick to the top.

In typesetting, a slug is any of several kinds of piece of lead or other type metal. One kind of slug is a piece of spacing material used to space paragraphs. In the era of commercial typesetting in metal type, they were usually manufactured in strips of 6-point lead. Another kind of slug is a single sort, bearing a single letter or any other symbol. More recently, a slug can be an entire line of Linotype typeset matter, where a single piece of lead has been cast bearing a line of text.

In modern typesetting programs such as Adobe InDesign, slugs hold printing information, customized color bar information, or display other instructions and descriptions for other information in the document. Objects (including text frames) positioned in the slug area are printed but will disappear when the document is trimmed to its final page size.

A California job case is a kind of type case: a compartmentalized wooden box used to store movable type used in letterpress printing. It was the most popular and accepted of the job case designs in America. The California job case took its name from the Pacific Coast location of the foundries that made the case popular.

The defining characteristic of the California job case is the layout, documented by J. L. Ringwalt in the American Encyclopaedia of Printing in 1871, as used by San Francisco printers. This modification of a previously popular case, the Italic, it was claimed reduced the compositor's hand travel as he set the pieces of type into his composing stick by more than half a mile per day.In the previous convention, upper- and lowercase type were kept in separate cases, or trays. This is why capital letters are called uppercase and the minuscules are lowercase. The combined case became popular during the western expansion of the United States in the 19th century.
