Ed McCollumUsing a split fountain printing technique, like on the posters for different bands. Load a one color press with multiple colors along the print roller and start printing. The colors blend and move as they get squeezed together over the course of the run. When you have a brown muck, you stop the press, clean the roller, load the ink and start over again. Made for some great psychedelic posters for rock groups. And cheap too.
