An intaglio printmaking technique, similar to engraving, the result is lines with slightly ragged edges because the burr or raised area created with the incising remains, unlike engraving where it is polished away. The first intaglio proofs that are pulled are of the best quality and most collectible because the burr wears away in the printing process. American artists noted for drypoint include James Smillie, Chauncey Ryder, Edward Hopper and Gertrude Albright. Source: Ralph Mayer, "A Dictionary of Art Terms and Techniques"; AskART biographies
