Printing method similar to engraving, but where a special needle of toughened steel or steel tipped with a diamond head is used to cut a design onto a metal plate. The plate is then inked and a print taken. The softer edged picture so produced is due to the ridge or burr left on each side of the cut, which catches the ink and comes out on the print.
