James Powlan began his career as a Printmaker in 1977. James is an
Aquatint specialist and perfected his Aquatint process at College of
Marin in California. It was there that he came up with the innovative
idea to use an airbrush to spray a resistant on the copper metal plates
he works on.
Aquatint itself is the process of melting tree resin particles onto a
polished metal plate to control how the acid eats into the metal
plates. Every step is done by hand from cutting and polishing the
copper to the inking and printing of the plate. Aquantint has been
used for hundreds of years by famous Printmakers such as Rembrandt van
Rijin in the 1600's, Goya in the mid 1700's to early 1800's and later
Pablo Picasso.
Shades and tonal areas are etched in the Aquatint process. Microscopic rosin dust
is melted onto the plate. Each tiny particle of rosin protects a surface of the plate.
The acid eats around a field of these particles and cuts microscopic shapes. The ink
gathers at the base of these in the printing process and prints a continuous tonal area.
