Product History In 1923, the spirit duplicating machine was invented. It used methanol to transfer ink from a spirit master to a sheet of paper. The machine was called a “ditto machine”, and the spirit master a “ditto master.” Rival technology of the time were mimeo and hecto processes. Both technologies have disappeared but the names live on and are often applied to the spirit process. In Europe, “Hecto” or “Hectograph” is the common name for spirit duplicating masters. The term “Dittos” is used in the United States. ReproFX Spirit units are free of lead and other heavy metal contamination and safe for application to the skin.
