This is a color viscosity etching that I did at the University of California at Berkeley. The concept of this type of print is that first the plate is etched to create different levels, then ink is wiped and rolled onto the different levels. The plate is inked and wiped to get color into the deepest level, then a hard roller is used to deposit ink on the top level, and finally a softer roller is used to deposit ink onto the middle levels. Different viscosities of ink are used, which allows one ink to resist another, thus depositing different colors on various parts of the plate. The plate is printed in one pass through the press.

Other prints using this method are, Aerial View, Computerization, Conquest of a Small Planet, and Crystal Growth.
