Abstract
A photosensitive film for plotting color images in daylight uses surface emulsion layers sensitive only to different and predetermined wavelengths of non-visible radiant energy. Each emulsion layer is developable to manifest a distinguishable color upon exposure to sensitizing radiant energy. Three sensitized emulsion layers can singly and collectively manifest any color upon development. During a plotting operation in daylight, a beam of radiant energy having a controlled composition of radiant energy wavelengths outside the visible spectrum is projected onto the film surface in the form of a spot. The beam of radiant energy and the film are moved relative to one another to cause the spot to sensitize the emulsion layers at different locations according to the desired plot. Changing the composition of the sensitizing wavelengths comprising the beam during a plotting operation causes the film to yield a multi-colored image upon development.
