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.
