pouncing
n.— «An overhead projector blows up his drawings into mural-size images. Then, Whalen uses an electric stylus to burn tiny holes into thin paper, which he can post on the mural panels. He bangs chalk through the paper and onto the panels, a technique known as pouncing. The chalk marks serve as a guide for where to paint.» —“Changing view” by Shirin Parsavand in La Mesa Press-Enterprise (Riverside, California) Sept. 10, 2005. (source: Double-Tongued Dictionary)
