This  monotype with prismacolor by artist Sylvia Petrie of Peacedale, RI is aptly titled Wave III.

Although it's a form of printing, monotyping produces a unique picture. Unlike a monoprint - which has an image engraved or raised on a plate - there is no image cut into a monotype plate. Instead, the color is drawn on the plate, which is smooth and nonabsorbent, then transferred to the paper.

Sylvia Petrie's work is seen at the David Charles Gallery of Providence and she is a member of The Print Consortium - an international group of printmakers.
