Typography

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 (leading), and letter-spacing (tracking), and adjusting the space between pairs of letters (kerning). 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 a decorative device, unrelated to communication of information. Typography is the work of typesetters (also known as compositors), typographers, graphic designers, art directors, manga artists, comic book artists, graffiti 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. Digitization 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. So at a time when scientific techniques can support the proven traditions (e.g., greater legibility with the use of serifs, upper and lower case, contrast, etc.) through understanding the limitations of human vision, typography as often encountered may fail to achieve its principal objective: effective communication. The word 'typography' in English comes from the Greek roots τύπος typos = 'impression' and -γραφία -graphia = 'writing'. Although typically applied to printed, published, broadcast, and reproduced materials in contemporary times, all words, letters, symbols, and numbers written alongside the earliest naturalistic drawings by humans may be called typography. The word, typography, is derived from the Greek words τύπος typos 'form' or 'impression' and γράφειν graphein 'to write', traces its origins to the first punches and dies used to make seals and currency in ancient times, which ties the concept to printing. The uneven spacing of the impressions on brick stamps found in the Mesopotamian cities of Uruk and Larsa, dating from the second millennium B.C., may be evidence of type, wherein the reuse of identical characters was applied to create cuneiform text. Babylonian cylinder seals were used to create an impression on a surface by rolling the seal on wet clay. Typography also was implemented in the Phaistos Disc, an enigmatic Minoan printed item from Crete, which dates to between 1850 and 1600 B.C. It has been proposed that Roman lead pipe inscriptions were created with movable type printing, but German typographer Herbert Brekle recently dismissed this view. The essential criterion of type identity was met by medieval print artifacts such as the Latin Pruefening Abbey inscription of 1119 that was created by the same technique as the Phaistos Disc. The silver altarpiece of patriarch Pellegrinus II (1195–1204) in the cathedral of Cividale was printed with individual letter punches. Apparently, the same printing technique may be found in tenth to twelfth century Byzantine reliquaries. Other early examples include individual letter tiles where the words are formed by assembling single letter tiles in the desired order, which were reasonably widespread in medieval Northern Europe. Typography with movable type was invented during the eleventh-century Song dynasty in China by Bi Sheng (990–1051). His movable type system was manufactured from ceramic materials, and clay type printing continued to be practiced in China until the Qing Dynasty. Wang Zhen was one of the pioneers of wooden movable type. Although the wooden type was more durable under the mechanical rigors of handling, repeated printing wore the character faces down and the types could be replaced only by carving new pieces.
