Engraving
The art of cutting lines or grooves in plates blocks or dies. Numismatically this takes the form of engraving images into the face of the dies used in striking coins, a process which has now been almost completely superseded by hubbing and the use of reducing machinery. In the production of paper money, intaglio engraving is still commonly practiced. ln this process the engraver cuts the design into a steel die and the printing ink lies in the grooves. The paper is forced under great pressure into the grooves and picks up the ink, and this gives banknotes their characteristic ridged feeling to the touch. Nowadays many banknotes combine traditional intaglio engraving with multicolour lithography or photogravure to defeat the would-be counterfeiter.
