One thing I love seeing when I visit museums is a printmaker's stage proofs. Here are five stages of one my acrylic resist etchings from the last 9 months (8" x 8" on copper plate). First stage: acrylic spray aquatint, with the cloud created by spit bite, then stopped out, and the figure and extra textures in the cloud created by immersion in ferric chloride.
Stage two: further stopping out and etching.
Stage 3: an acrylic hard ground, line drawing, then etching.
Stage 4: another acrylic hard ground, line drawing, and drypoint.
Stage 5: burnishing and scraping in the figure, and some final drypoint.
This is my studio blog. I also have another blog, Praeterita, which contains more general art-related posts.
