Slab-serif type was perhaps first commercially introduced by London typefounder Vincent Figgins under the name 'Antique', appearing in a type-specimen dated 1815 (but probably issued in 1817). The first known example of a slab-serif letterform is woodblock lettering on an 1810 lottery advertisement from London. Some of the type designs appearing around this time may be based on signpainting and architectural lettering traditions, or vice versa. Others had completely new structures: sans-serif letters, based on classical antiquity, and reverse-contrast letterforms. Some were developments of designs of the previous fifty years: ultra-bold types known as ' fat faces', which were related to ' Didone' text faces of the period but much bolder. Poster-size types began to be developed that were not merely magnified forms of book type, but very different and bolder. Slab serif lettering and typefaces appeared rapidly in the early nineteenth century, having little in common with previous letterforms.ДЄs the printing of advertising material began to expand in the early nineteenth century, new and notionally more attention-grabbing letterforms became popular. Slab serif fonts were also often used in typewriters, most famously Courier, and this tradition has meant many monospaced text fonts intended for computer and programming use are slab serif designs.ДЄ sample of the typeface Courier, a slab serif face based on strike-on typewriting faces. Some fonts oriented towards small print use and printing on poor-quality newsprint paper may have slab serifs to increase legibility, while their other features are closer to conventional book type fonts. These designs may have bracketed serifs which increase width along their length before merging with the main strokes of the letters, while on geometrics the serifs have a constant width.Дisplay-oriented slab serifs are often extremely bold, intended to grab the reader's attention on a poster, while slab serifs oriented towards legibility at small sizes show less extreme characteristics. Others such as those of the Clarendon genre have a structure more like most other serif fonts, though with larger and more obvious serifs. Some such as Memphis and Rockwell have a geometric design with minimal variation in stroke width: they are sometimes described as sans-serif fonts with added serifs. Slab serifs form a large and varied genre. Slab serifs were invented in and most popular during the nineteenth century. Serif terminals may be either blunt and angular ( Rockwell), or rounded ( Courier). In typography, a slab serif (also called mechanistic, square serif, antique or Egyptian) typeface is a type of serif typeface characterized by thick, block-like serifs. Some headings and the lower passage are in Didone type, but much body text is slab serif. Slab-serif type on the heading of a Chartist poster, 1848.
