ABSTRACT:
Both a system and process are provided that utilize infra-red dyes to integrate data in a visually non-perceptible form into a printed, color image. The system operates by first selecting the areas of greatest light absorptivities out of the image to record the data, which may be sound information. Next the system determines a target color for each point on the image, as well as the amount of cyan, magenta and yellow coloring agents that must be deposited at each point to attain the desired color. The system then determines the color component additions that the infra-red dye will add to the darker areas when it is over printed thereon. The system subtracts some of the cyan, magenta and yellow coloring agents for each point in the selected areas prior to printing the image so that the target color is attained after the infra-red dye is printed over the selected areas.
