I used to work somewhere where perspex was used as a glazing material for framed pictures. One of the problems of using perspex is that it scratches very easily and the scratches are virtually impossible to remove once theyre there. Fortunately those very properties make it a great material for use as a printing plate. Any sharp tool will create a line that will hold ink beautifully. Here are a few large quick life-drawings using perspex in this way. For any printmakers keen on this drypoint technique I suggest a thinner and more user friendly alternative material called Makrolon polycarbonate (1mm is a good thickness) made by Amari plastics.
