JOHANN GEORG WILLE (1715–1808). The Message. 1762.
DRYPOINT is an intaglio process in which the image is engraved into a copper or zinc plate with a diamond or steel needle. Characteristic of drypoint is the burr that appears beside the lines, i.e., the residual metal is not removed as in copper engraving. This technique allows to produce very thin lines, but the plate yields very few prints (10 to 40).
