Abstract:
A process for illuminating an object with a first spectrally distinct area, comprising the steps of:(a) determining the spectral reflectivity of said first spectrally distinct area,(b) identifying a first wavelength portion of such first spectrally distinct area that reflects more light from a light source than absorbs such light and the extent to which said first wavelength portions of such first spectrally distinct area reflect said more light than absorb said more light,(c) identifying the maximum reflectivity of said first wavelength portion of said first spectrally distinct area when illuminated with said light source,(d) identifying that portion of said first wavelength portion which has a reflectivity less than about a specified percentage of said maximum reflectivity,(e) preparing a digitized image of said first spectrally distinct area, thereby producing a first digitized image(f) modifying said digital image to delete said portion of said first wavelength portion which has a reflectivity less than said specified percentage of said maximum reflectivity, thereby producing a first modified digital image,(g) forming said first modified digital image onto a medium, thereby producing a modified image medium,(h) illuminating said modified image medium with said light source, thereby producing a first modified image, and(i) imaging said first modified image upon said object with an imager.
