Short for 
Benjamin Day, the 
Benday Dots printing process combines two (or more) different small, colored dots to create a third color.  Depending on the effect, color and 
optical illusion needed, dots may be proximal or overlapping. 1950s and 1960s pulp 
comic books used Benday dots in 
primary colors to inexpensively create shading and the secondary colors of green, purple, orange and flesh tones.  Considered his trademark, American artist 
Roy Lichtenstein enlarged and exagerated Benday dots in many of his paintings and sculptures.
