-
A process by which an engraved copperplate or an electrotype from an engraved plate of steel or copper has a film of iron deposited over its surface by electricity, in order to protect the engraving from wear in printing. By this means an electrotype of a fine engraving which, if printed directly from the copper, would not yield 500 good impressions, can be made to yield 3,000 or more. Whenever the film of iron becomes so worn as to reveal any part of the copper underneath, it is removed and a fresh coating deposited; and in this way as many as 30,000 good impressions have been printed from the electrotype of a finely-engraved plate.
