A monoprint is a single print created, in this artist's case, by painting oil-based lithographic ink onto a plexiglass plate and then transferring the image onto paper with a press.
To create a viscosity print you go one step further. This form of printing creates a bleeding or mixture of inks and colors. With heavy amounts of printer's oil I blend oil and ink and paint the plate. To unify the picture areas on the plate purposely left blank. Upon this plate a rolled color with no added oil to the ink is applied. The oiled ink resists the uncoiled ink however a blending or filling is occurs. Frequently, an added textural process takes place due to what pressure you roll the uncoiled ink on the plate. Doing viscosity prints I normally pull one or two ghosts as I heavily apply ink with brushes on my plates. This leftover ink on my plates allows softer images to emerge.
