1. A method of processing a plurality of source images, comprising:
- receiving image data representative of a polychromatic source image and encoding first and second separation images representing the polychromatic source image in a composite image;
rendering the composite image on a substrate by use of a plurality of colorants; and
recovering the encoded separation images from the rendered composite image, such that the polychromatic source image is made distinguishable as a normalized color image, by subjecting the rendered composite image to an illuminant having a predefined spectral power distribution that is selected to reveal the normalized color image.

11. An imaging system, comprising:
-
a spectral multiplexer for receiving image data representative of a polychromatic source image and for processing the image data to encode at least first and second separation images representing the polychromatic source image in a composite image, and for providing a composite image data signal; an image rendering device which is responsive to the spectral multiplexer for receiving the composite image data signal and for rendering the composite image on a substrate; and a spectral demultiplexer for subjecting the rendered composite image on the substrate to illumination by an illuminant having a predefined spectral power distribution for which the polychromatic source image was encoded, such that a normalized color image derived from one of the encoded source images is recovered when the rendered composite image is subjected to the illuminant. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
