Abstract:
1. A method for preparing an image described in a multi-color color space for rendering, in a single-colorant color space, the method comprising: collecting histogram information from the multi-color color space image wherein bins within the histogram classify image pixels based on luminance information and hue information; classifying peaks within the histogram that have similar luminance as conflicting colors; applying at least one distinct spatial modulation to, and only to, at least one respective single colorant version of at least one of the conflicting colors in a single colorant version of the image, thereby ensuring that all single colorant versions of colors in the image are visually distinguishable from one another while minimizing distortions in a remainder of the single colorant version of the image; and at least one of storing and rendering the single colorant version of the image.
