In typography, a typeface (also known as font family) is a set of one or more fonts each composed of glyphs that share common design features. Each font of a typeface has a specific weight, style, condensation, width, slant, italicization, ornamentation, and designer or foundry (and formerly size, in metal fonts). For example, "ITC Garamond Bold Condensed Italic" means the bold, condensed-width, italic version of ITC Garamond. It is a different font from "ITC Garamond Condensed Italic" and "ITC Garamond Bold Condensed", but all are fonts within the same typeface, "ITC Garamond". ITC Garamond is a different typeface from "Adobe Garamond" or "Monotype Garamond". (These are all alternative updates or digitisations of the typeface Garamond, originally created in the 16th century.) There are thousands of different typefaces in existence.
Type foundries have cast fonts in lead alloys from the 1450s until the present, although wood served as the material for some large fonts called wood type during the 19th century, particularly in the United States. In the 1890s the mechanization of typesetting allowed automated casting of fonts on the fly as lines of type in the size and length needed. This was known as continuous casting, and remained profitable and widespread until its demise in the 1970s. The first machine of this type was the Linotype machine, invented by Ottmar Mergenthaler. Digital type became the dominant form of type in the late 1980s and early 1990s. Digital fonts store the image of each character either as a bitmap in a bitmap font, or by mathematical description of lines and curves in an outline font, also called a vector font.
