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.

A method of exposing a photosensitive material wherein said material comprises a supportive substrate, said substrate being at least partially transmissive and having a layer of microcapsules on one surface thereof, said microcapsules containing a color precursor and a photohardenable or photosoften

A method of exposing a photosensitive material wherein said material comprises a supportive substrate, said substrate being at least partially transmissive and having a layer of microcapsules on one surface thereof, said microcapsules containing a color precursor and a photohardenable or photosoftenable composition, the method comprising the steps of: supporting said substrate to define a forward surface of said substrate carrying said microcapsules, and to define an opposite, rearward surface of said substrate; positioning on the side of said substrate corresponding to said rearward surface a reflective surface, said reflective surface having a greater reflectivity of light within a selected wavelength band than outside of said band; and directing an exposure beam onto said forward side of said substrate, whereby at least a portion of said beam passes through said substrate to said reflective surface and is reflected back through said substrate, said greater reflectivity within said band increasing the relative color content of said beam at wavelengths within said band with respect to wavelengths outside of said band, wherein said reflective surface is a dichroic mirror.
