PRINTING, the art of taking impressions from characters or figures, moveable or immoveable, on paper, linen, silk, &c. There are three kinds of printing; the one from moveable letters, for books; another from copper-plates, for pictures; and the last from blocks, in which the representation of birds, flowers, &c. are cut, for printing calicoes, linens, &c. the first called common-press printing, the second rolling-press printing, and the last calico, &c. printing. The principal difference between the three consists in this, that the first is cast in relief, in distinct pieces; the second engraven in creux; and the third cut in relief, and generally stamped, by placing the block upon the materials to be printed, and striking upon the back of it.
