Then damp paper which is pressed over the plate into the grooves picks up the ink. Stewart's plates have deep grooves. Stewart continues to experiment with various plate materials such as copper, zinc, masonite, polyurethane coatings, high-temperature cement, aluminum, various plastics, ceramic and magnesium for deep etching. Some of the more complex plates used for printing seem themselves works of art, with their sculptural depressions and silvery surfaces mottled by the chemicals and inks used on the plates. It is a thick, textured paper.
Some prints are deep rich colors, some are subtle pastels.
The equivalent of academic publishing for university art faculty is exhibiting their work. For a one-person exhibit, which Stewart likes to have at least once a year, he may make a hundred or more prints to have 25 pieces to display. He begins with photographic patterns that interest him. Many are aerial photographs. For my purpose, images taken from plane windows are adequate.
