" Relief etching on copper, or ecktypography, was the name which A. Dembour, an engraver in Metz (Lorraine), called the relief process invented by him in 1834. He made drawings on copper plates with greasy varnish and etched away the bottom, which was not covered by the varnish. This is perhaps one of the first publications on the so-called relief etching for letter press printing..." Eder's HISTORY OF PHOTOGRAPHY, 1945.
