There are many types of printmaking - I'm drawn to monotypes because the process is akin to drawing or painting.  Working on a plexiglass plate, you apply and remove ink with various tools to create an image.  Mixing colors with ink is more of a challenge than with oil paint; I've found more success making black and white monotypes, or using a limited range of color.  Printing monotypes is an exciting mystery since you can't predict exactly how the pressure of the press will affect the ink. You can end up with some interesting surprises.
