“This project addresses the special case of selecting inks for duotone printing, a relatively inexpensive process in which just two inks are used. Traditional duotone printing almost always uses black as one of the two inks. The resulting reproduction is an ‘enhanced grayscale’ image: a grayscale image with a hint of the chosen accent color. We would like to use duotone printing to achieve full color reproduction. Our system takes an image as input and allows the user to select 0, 1, or 2 inks. The output consists of the remaining inks or inks that will best reproduce the image as a duotone and the appropriate color separations.”
