Continuing my experiments with different mixtures of acrylic-based resists, I'm getting some idea about which combinations of materials work best in order to print a good image, and to get a clean plate surface around the lines. All of the prints below were taken from re-used 6" x 4" copper plates. The inks are Akua intaglio inks. The following plate had three layers of dried resists made from GAC 200 and a few drops of black airbrush ink. The lines were drawn into the dried resist using an etching needle. The print looks remarkably like a hard ground etching, even though no mordant was involved. It's difficult to avoid air bubbles in the GAC 200, though, but I decided to let those stand as part of the texture of the print: The next plate is the same mixture, the drawing was done with varying pressure of the etching needle, so that part of it looks like en etching, parts of it like a drypoint. Some of the resist dried in tiny ridges that picked up ink ...
