Abstract
A method and apparatus for color correction while exposing a photosensitive material are disclosed. The material comprises a supportive substrate which is at least partially transmissive and has a layer of microcapsules on the surface thereof. The microcapsules contain a color precursor and a photohardenable or photosoftenable composition. The substrate is positioned on or near a reflective surface having greater reflectivity within a selected wavelength band. An exposure beam is directed onto the substrate, whereby at least a portion of the beam passes through the substrate to the reflective surface. Since the surface reflects a greater portion of the light within the selected band, color correction is achieved.
