1913, from Ger. Rotogravur (originally, in full, Deutsche Tiefdrück Gesellschaft), said to blend two corporate names, Rotophot and Deutsche Photogravur A.G. Etymologically, the roots are L. rota "wheel, roller" and Fr. gravure "engraving." The process was used for printing photo sections of newpapers and magazines, so that the word came to be used for these.
