Zentak Grotesk is a version of Akzidenz-Grotesk halbfett, added in 1965 to Chartpak’s Deca-Dry range of faces for dry transfer lettering. [1965 catalog] [The International Blue Printer] Also carried by Celio-Tac’s Transfertype and by Alfac. [Stephenson 1987] Alfac had a second italic style that appears to be an adaptation of Helvetica Medium Italic, but with a straight-legged ‘R’ (and ridiculously high dots on ‘i’ and ‘j’). [Alfac catalog] Possibly related to the German Zentak Haftdruck GmbH.
