A multilined (5-line) typeface by Rudolf Koch, released by Klingspor in 1930 [Reichardt]. Not registered at the VdS before July 1931. Together with Zeppelin (1929), Prisma can be regarded as a display extension to his Kabel (1927–30).
Also carried by Letraset and Mecanorma. Latter’s Prisma Neo is a distant cousin. Numerous adaptations and extensions from the phototype era, including Bauhaus Prisma, Futura Prisma & Prisma Graphic and Prismania.
