Lexicon (designed in 1992 by Bram de Does) is pre-eminently suitable for output on laser and other low-resolution printers and for typesetting in small sizes.
Lexicon consists of two main groups: Lexicon No.1 and Lexicon No.2. Lexicon No.1 has short stems (ascenders and descenders); Lexicon No.2 has 'normal' stems. Both groups share the same widths thus making it possible to change fonts without reflowing text.
Each main group contains 12 variants: six upright weights (A to F) and six italic weights (A to F). A is the regular weight, and F is the boldest weight.
