Collotype printing is a classic photographic printing technique invented by Alphonse Poitevin (France) in 1855 and successfully commercialized by Joseph Albert (Germany). It uses a gelatin-based plate and achieves a rich tonal rage without relying on halftone screens. Moreover, the high pigment content of its inks allows it to offer excellent durability. Although this technique has almost disappeared, Benrido has evolved and sustained it. This paper explains the history, characteristics, and future of the process, focusing on Benrido's collotype.
