Drypoint engraving is one of the 'Intaglio' types of printmaking, Intaglio literally meaning 'to carve'. Where-as in block printing you print from the areas that are left raised, with intaglio, the ink comes from the recesses that have been engraved. Copper or zinc are often used as the plate in drypoint, but you can also get excellent results from acrylic and board. The design is scratched onto the plate with a sharp point then ink applied over the surface. The excess is rubbed away, leaving it only in the design. With damp paper and pressure the drawing is forced out onto the paper.
