With the airbrush, you spray little acrylic dots on the copper plate and then when you place the plate in the etching solution, the solution etches the spaces between the dots and an area of nice solid tone is created - you hope! Actually, you may not care if you create a nice solid tone. Maybe you want it to be mottled.....it depends on the effect you want. Really, the effects you can get by varying one thing or the other is all quite fascinating!
