I used the plates in a slightly different way. Instead of suga-lift, I varnished the plate and then scratched into it. I brushed the ink on the plate with the following results of mono-print type effects.
Sean Scully compared painting and printmaking with the following:
There is something very elemental about taking a plate, covering it with black material, hard ground, and then just scratching out a drawing: it's the equivalent of a line drawing. And when the acid bites into the metal and the ink sits in the metal and then it is transferred to the paper, it stands up on the paper and there is an indentation. And then what you have is the result of something that is quite mysterious as a process. Whereas with the painting, it is a direct result of putting down a brushstroke.

I manipulated the surface ink on the following plate with varying results.
