Abstract:
An automated process for coloring a superplxel, defined within a computer aided design system, containing a specified number of constituent pixels N and using a pre-defined set of process colors, for use in coloring a pattern area on an absorbent substrate having a specified target color, said process comprising the steps of:a. determining the color component values of said set of process colors and the color component values of said target color, wherein said color component values of said process colors, as defined, include an accommodation for the reflectivity of said substrate; b. defining a combination of said process colors, each of said process colors having an individually specified concentration to be assigned to said superpixel that, when blended together, will produce said target color, wherein said assignment of process colors to specific constituent pixels is constrained by a minimum specified concentration; and c. determining, within said combination of said process colors of Step (b), an assignment of specific concentrations of said process colors to specific constituent pixels that produces a desired distribution of colorants within said superpixel.
