A photomechanical process by which pictures, typeset matter, and especially magazine supplements in newspapers, are printed from an intaglio copper cylinder. On "shell cylinders", used to speed setup for the next publication, a nickel sleeve covers the copper cylinder, then is electroplated with copper for plate etching; thus permitting the sleeve to be stripped for later recovery, instead of refinishing the base cylinder each time. Process invented by Carl Kleitsch (1894); term derived from the name of a Berlin printing firm ("Rotogravur Deutsche Tiefdruck Gesellschaft"), which was formed from the merger of two other firms ("Rotophot" and "Deutsche Photogravur"). Compare photogravure; see gravure, gravure press.
