A brush is a tool for applying liquids, such as ink or paint. In digital image editing (e.g., digital painting or Photoshop, GIMP, etc.), we also speak of brushes, which are used to draw on the screen. Brushes are also used for hair care and in cosmetics. Fiberglass brushes and some other types of brushes are used to clean surfaces. Brushes are either manufactured by machine in industry or still handcrafted by brush and paintbrush makers. The latter is especially true for brushes that have to meet special requirements, such as in porcelain painting.

Font is a set of characters designed in a specific typeface and realized according to the respective technical conditions. It is used for text creation and processing, typesetting and printing, and forms the basis of typography. A typesetting font consists of individual characters, the glyphs: usually lowercase letters, uppercase letters, umlauts, accented characters, numerals, ligatures, punctuation marks, special characters and small caps. These are assembled manually, by machine or electronically to form words, lines and more complex orders.

The scope of such a character set depends on the technology and the intended application radius of a typesetting font. The functional efficiency of the characters of a typesetting script requires, in the case of Western European alphabetic scripts, that they are arranged horizontally, in neighborhood with other characters of the inventory, according to a uniform rhythmic and stylistic principle. Only then can they be combined into a coherent, graphically balanced typeface.

The form of typefaces in general, and that of typesetting in particular, is characterized by two different modes of access: Reading and seeing (in the sense of looking). These are due to the "double character of writing." Writing is both abstract (semantic level) and sensuously concrete (semiotic level). In routine reading, attention is focused on the abstract side of writing. Records in alphabetical writing are not deciphered letter by letter, but word and line outlines are grasped holistically by means of eye jumps (saccades). In the process, details of the form of the written image escape attention, recede into the background, and are not registered or are invisible.
