A New Photometer for Control of Color Printers

Mehrdad Azarmi, Richard A. Walker

A new film gate photometer has been designed for the control of color printers. While doing away with the disadvantages of the sensitometric method of control, the new meter, with its series of probes, provides: (1) red, green, blue and “whitelight” irradiance (exposure) measurements directly at the film plane; (2) a check of the uniformity of the illumination across the film-gate area; and (3) monitors the illuminance at the printer eyepiece while it is in use. Photometric and photographic tests have indicated that the photometer is an excellent tool for complete control of color printers.
