"The Series CH printer operates on the additive color principle, wherein the light from its single 1200 watt printing lamp is slit into red, green and blue color beams by selectively reflecting and transmitting dichroic mirrors. Light changes occur while the frame line is at the aperture and between successive scenes, and may be controlled either by the standard film notch or by means of the R-F patch cue system. Dichroic mirrors are located in the optical housing and are readily accessible for cleaning or replacement. The printer is equipped with three light valves (one for each color beam) and a tape reader which provides the signals to actuate the shutters and reads the program tape for the next scene. The light valves decode the signals and place the decoded information in memory so that it will be ready for instantaneous light change. All light valves are identical and each can be replaced as a unit in a matter of minutes" (Professional Equipment Division Bell & Howell Printer Manual Model "C" Continuous Contact Motion Picture Film Printer, Chicago, Bell & Howell, 1973, p. 1-2).
