Typeface

In typography, a typeface is a co-ordinated set of letter designs, making a complete alphabet, and generally intended to be made into a font for printing or use on a computer display.

The art of designing typefaces is called type design, being the occupation of a type designer.

A font is a set of glyphs (images) representing the characters from a particular character set in a particular typeface. In digital fonts, the image of each character may be encoded either as a bitmap (in a bitmap font) or by a higher-level description in terms of lines and curves enclosing space (an outline font, also called "vector font").

The term "font" has been used for centuries to refer to the contemporary technological device used to print in a particular size and typeface (though in phototype and digital type, it no longer refers to a specific size). Virtually all fonts were cast in various lead alloys from the 1450s until the middle of the 20th century. A few large fonts were made of wood, especially in the USA. This is known as wood type[?]. There was a relatively brief overlapping period (ca. 1950s-1990s) where photographic technology, known as phototypesetting[?], was used; fonts came on rolls or discs of film. From the mid-1980s the move to digital typography[?] has been relentless and the term font nowadays almost always refers to a file containing scalable, outline letterforms, usually in one of several common formats. Some fonts, such as Microsoft's Verdana are intended primarily for on-screen use.

Categorization criteria

Of all the blackletter typefaces, the Gothic ones most closely resemble the Textura callygraphy used with manual copying of books. A Gothic typeface was thus also carved by Johannes Gutenberg when he printed his 42-line Bible, including a large number of ligatures[?] and common abbreviations. While in Germany, Gothic fonts were quickly displaced, they remained in use in great variance and are frequently referred to as Old English typefaces.
	b)	Schwabacher typefaces were predominant in Germany from about 1480 to 1530. Most importantly, all of the works of Martin Luther, leading to the Protestant Reformation, as well as the Apocalypse of Albrecht Dürer (1498) were printed in this typeface. It was probably first used by Johannes Bämler, a printer from Augsburg, in 1472. The origins of the name are unclear; some assume that the typeface was designed by a typeface carver from the village of Schwabach who worked externally and was thus refererred to as the Schwabacher.
	c)	Most commonly known among the blackletter typefaces are those of the Fraktur family, which started when Emperor Maximilian I (1493-1519) established a series of books and had a new typeface created specifically for this purpose. Fraktur faces were in wide use in Germany until the end of World War II; see the Fraktur article for details.

2. Serif fonts

Serif fonts are in turn divided into four major groups:

a)	Renaissance, with only slight difference in thickness within each glyph; this category includes the Garamond and Palatino typefaces.
b)	Baroque, where the thickness within each glyph has greater variety; this category includes Baskerville[?] and Times Roman.
c)	Classicist, with the most variance of thickness within each glyph. This includes the Bodoni and Century Schoolbook[?] typefaces.
d)	Modern fonts, especially those designed primarily for decorative purposes, frequently fall out of these categories. For example, slab serif fonts such as Rockwell look artificial on purpose, with almost rectangular shapes.

3. Sans-serif fonts

Sans serif designs are a relatively recent typographical phenomenon in the history of type design. The first specimen appears to be the two-line English so-called "Egyptian" font released in 1816 by William Caslon[?]'s foundry, England. They are commonly, but not exclusively used for display typography applications such as signage, headings and other situations where clear meaning is imperative but continuous reading is not required.

Sans serif designs are broadly divided into 4 major groups for the purposes of type classification:

a)	(todo sample image) Grotesques, early sans serif designs, such as Grotesque[?] or Royal Gothic[?].
b)	Neo-grotesques, modern designs such as Standard, Helvetica (Arial) and Univers[?].
c)	Humanist (Edward Johnston[?]'s Railway type, Gill Sans[?] or Frutiger).
d)	Geometric (Futura or Spartan).

Other commonly used sans serif fonts include Lucida[?], Arial, Optima, Tahoma[?] and Verdana.
