A registration pin is a device intended to hold a piece of film, paper or other material in place during photographic exposure, copying or drawing.
Registration pins are used in offset printing and cartography, in order to accurately position the different films or plates for multi-color work.
In traditional, hand-drawn animation, the registration pins are often called pegs, and are attached to a peg bar.
Also, in traditional, hand-taped printed circuit board artwork, usually at two or four times actual size. Sometimes on a single transparent base, usually mylar, with Layer 1 being on the front and Layer 2 being on the back, in red and green, respectively, for later "separation" into component parts using a process camera.

Famous quotes containing the word pin:
“Suddenly we have a baby who poops and cries, and we are trying to calm, clean up, and pin things together all at once. Then as fast as we learn to cope—so soon—it is hard to recall why diapers ever seemed so important. The frontiers change, and now perhaps we have a teenager we can’t reach.”
—Polly Berrien Berends (20th century)
