Belgian manufacturer of cut out [before 1961] and rub-down lettering products. Also active in France, the Netherlands, Germany, and the UK, at least into the early 1990s. Many of the typefaces shown in an undated (1980s) catalog stem from ITC, Berthold, and others, but Alfac issued various original designs, too.
The company was at one point named Alfac Decadry S.A., suggesting a possible relation to Chartpak and their Deca-Dry brand. In 2008, Alfac Decadry S.A. was acquired by APLI Paper S.A.U.
