graphotype

Century Dictionary and Cyclopedia

1. n. A process of making blocks for use in surface-printing. Drawings are made on a thin surface of finely prepared chalk with a silicious ink. When dried, the soft parts are brushed away, and the drawing remains in relief; stereotypes are then made from the block. In a later form of the process the chalk surface is superseded by a zinc plate covered with finely powdered French chalk brought to a hard and firm texture by great pressure.
2. n. A type-writer for embossing letters upon thin sheets of metal to form type for use in an addressing-machine.
3. n. A form of type-casting and -setting machine.

1. n. A process for producing a design upon a surface in relief so that it can be printed from. Prepared chalk or zinc oxide is pressed upon a smooth plate by a hydraulic press, and the design is drawn upon this in a peculiar ink which hardens the surface wherever it is applied. The surface is then carefully rubbed or brushed, leaving the lines in relief.
