A commercial printing technique using small dots of color, named after 19th-century illustrator and printer Benjamin Henry Day. Ben-Day dots were used in color comic books in the 1950s and ’60s to create effects of shading and secondary colors inexpensively. American Pop artist Roy Lichtenstein (1993–1997) used stencils to imitate the look of Ben-Day dots in his comic-inspired paintings.
