Function

To transfer individual designs from an original engraving to a master die prior to the preparation of a gravure printing plate.

Technical

This is a siderography, or transfer, press used in the making of gravure printing plates for banknotes. It employs principles developed in the United States by Jacob Perkins in the early 19th century. Individual parts of a banknote design are engraved separately by hand on individual steel dies. Each die is first hardened then placed in the siderography press, where under great pressure the image is tranferred to a steel roll. All rolls comprising the complete design are then hardened and then each in turn is used to impress its image in the steel master die. From this flat master die the actual printing plates are made by electrotyping. For more information see: Robert N. Steffens, Engraved Stationery Handbook (New York: 1950), pp. 143-144.
