Final answer:
To create a drypoint print, an artist uses a burin to scratch an image into a metal plate, creating a burr that holds the ink for printing. This technique is distinct from etching where a wax coating and acid bath are used or aquatint which involves a resin and needle to create tonal effects.
Step-by-step explanation:
When creating a printmaking piece, the specific technique determines the tools used and the effect on the plate. In the case of drypoint, the artist uses a sharp instrument known as a burin to incise or scratch an image directly into a metal plate, which in this instance is typically made of copper. As the burin scratches the surface, it creates a burr, which is a slight raised edge of metal that catches ink and results in a rich, soft line when the plate is inked and printed. A burin is similar in appearance to a metal engraving tool, with a sharp point and a rounded handle that fits in the palm of the hand. This process differs from etching, where wax is applied to the plate and an image is scratched into it before being placed in an acid bath. Aquatint also utilizes an acid bath but first applies a resin to create tonal effects, and the artist uses a needle to draw into the resin, exposing the metal for etching.
