In order to enable quick and easy reproduction, all drawings were originally based on a coarse grid and could be executed with compass and rulers. The "Normblatt" ("standards sheet") DIN 1451, "Schriften" ("Typefaces") was released preliminarily in 1931; then, with some minor changes in 1936, it was released as an official standard. In 1938, Temporary Order No. 20 required DIN 1451 to be used on the new German "Autobahn" (motorway) system. Due to this and similar regulations, DIN 1451 still dominates German public lettering today.
