Ditto machine

The duplicator that produces purple copies is NOT a mimeograph. It

is a spirit duplicator (called alcohol process duplicator in

Europe). It does not use ink. It uses a master. The master consists

of a sheet of paper attached to a special (usually) purple carbon

paper. It also uses spirit fluid (methanol in U.S.; ethanol in

Europe)>

In the US it was often called a Ditto machine. Ditto was one

manufacturer of these machines. I have also heard it called a

Rexograph--after another manufacturer. This type of machine was

also made by A.B. Dick, Heyer, Roneo, Standard, etc.
