What Is a Mimeograph?

The mimeograph was an american file plate stencil duplicator. A patent for this sort of device had been filed for this by duplication inventor a eugenio de zocato in 18 74. The key here is that the ink could then flow into these perforations to reproduce the writing. This was also called the papyrograph. And then there was a more advanced typograph that was also produced. It operates on the principle of a stencil, similar to screen printing techniques that were not new at this time.
