glyphography

[Gr. glyphe =a carving, and graphoto write, to draw.) A name given by Mr. Palmer to his relief line engraving. A thin ground of wax is spread upon the plate; this is etched or cut away so as to give the design in intaglio. The ground is now covered with a film of graphite, after which metal is precipitated upon the metal in an electro-bath, giving a metallic plate with the design in relief. The copper shell is backed with lead and used as an ordinary printing surface. glyptic, a. [Gr. glyptikos = carving; glyphōto engrave; Fr. glyptique.] 1. Ord.
