Robert Gamblin formulated these etching inks at the request of printmakers in the Pacific Northwest who wanted strong reliable inks for edition printing. Because of their high pigment load, Gamblin Etching Inks are a much better value than lower priced etching inks which are full of extenders. Inks are available in 300 ml cans.
