The monotype process appeals to painters and printmakers alike. Some artists
approach the process more as they would painting or a drawing. They create
the image directly on the plate with printers ink or oil paints, using a
variety of colors. Most early monotypes were made on metal plates, but
artists soon realized they could make an image on any smooth, non-absorbent
surface like transparent glass or plastic.
"The light field monotype is an additive process. In other words, the artist
begins with a blank surface and adds a color as if they were making a
painting, they were painting with a brush."
