Printmaking
Spirit duplicator
A spirit duplicator (also referred to as a Ditto machine in North America, Banda machine in the UK or Roneo in France and Australia) was a printing method invented in 1923 by Wilhelm Ritzerfeld and commonly used for much of the rest of the 20th century. The term "spirit duplicator" refers to the alcohols which were a major component of the solvents used as "inks" in these machines. The device coexisted alongside the mimeograph.
