Spirit Duplicator ... is essentially a hectograph which uses spirits, or alcohol to make its duplications.
In order to duplicate documents, it was necessary to first copy them onto the appropriate spirit master.
"This machine printed from a "master" created in the same manner in which hectographic master sheets for spirit duplicators were made, but considerably before their introduction" (Rhodes and Streeter 109).
