New litho, reverse style. First you ink up the whole stone until it's a deep, velvety black. Then you scratch out hard edged whites with a razor, and erase out softer whites with snakeslip. Then your etch uses 27 to 35 drops of nitric acid (as opposed to the 7-9 with a normal litho). It's much harder to print, but I like the darkness and drama that is possible. it's the lithography equivalent to an erased-out soft charcoal drawing.
