In the individual cultures, characters for the representation of texts
have developed over centuries. Writing fulfils the prerequisite for the documentation of events. Therepresentation of writing was mechanised by the printing of prefabricated characters which, when strung together, produce words and texts. This history gave rise to the mechanical and optical typesetting technique, phototypesetting, which is reflected today in electronic form in text, typesetting and pagination programs in personal computers
(PCs).Due to the enormous computing power of
modern computers, the many possibilities of type and typesetting technology can be implemented.
These include type style, typeface, font, type size, type run and boldness. As a unit for type size, the unit "point" used in classical typesetting technology, from the Didot point, has been adopted. One point (dp) corresponds to 0.38 mm. The type width is given in pica, one pica being equal to 1/6 inch or 12 points.
As far as typesetting is concerned, further design features are the type area, the type of typesetting such as flutter or justification, and the weft. There are also other style elements for the typeface and typesetting technique.
