Mezzotint is also considered to be intaglio, more specifically drypoint. Drypoint means that no chemicals are used during the process, only sharp tools that pick up tiny specks of copper, called burrs, which hold ink. Mezzotint is one of the best ways to achieve various tones in printmaking. A tool called a rocker is used to roughen up the plate surface with its many “teeth”, picking up thousands of burrs, which when strategically scraped or burnished down with specific tools, can create beautiful ranges of tones when printed. Mezzotints are known to create “velvety” rich blacks that are hard to achieve in other forms of printmaking.
