'''Foil cues''' are short strips of adhesive foil attached to the edge of a 35mm projection print. They are used to facilitate auditorium and projection booth automation, often in a [[multiplex]] setting. When using foil cues, a proximity cue detector is embedded somewhere in the projector's normal thread path; when the foil cue passes through the proximity cue detector, the circuitry closes the appropriate relay and triggers the desired automated function. | '''Foil cues''' are short strips of adhesive foil attached to the edge of a 35mm projection print.
