So here's what I was doing this evening:
It's a monoprint prepared on an acrylic plate. Lines incised with a stylus, some textures worked in with sandpaper. Then water-soluble graphite worked into the lines, and watercolor paint brushed on wet and allowed to dry. Run through the press, the wet paper releases and absorbs the pigment. This particular paper is also interesting: it's recycled from an old art book. The number 16 at the bottom is embossed on the paper. I like the mottled effect of the watercolor which pooled on the surface of the plate as it dried.
