Imposing stone

nounStandard termPrinting

A flat, heavy surface used for assembling and locking up metal type.

A perfectly flat, rigid work surface used in letterpress printing for arranging pages of metal type and locking them into a chase. Originally made of smooth marble or limestone, later versions were cast iron or steel but kept the traditional name. The heavy, flat surface ensures all type characters sit perfectly level before printing.
