Summary
An electrically driven spirit duplicator.
The spirit duplicating method is also referred to as the direct, or fluid, process. The master copy is prepared by typewriter, handwriting, punched card, or computer-printing devices. Master copies can also be prepared by copying machines and microfilm reader-printers. The master sheet is then fastened to a rotating drum. As copy sheets, slightly moistened by a special liquid, are brought into direct contact with the master sheet, a minute amount of the carbon is transferred to them, resulting in finished copies. Multicolour duplication in one operation is possible. A further advantage of the spirit process is that information can be added to or deleted from the master. Up to 300 copies can be made from one master sheet. This machine is entirely mains operated.
