Doubling the Color Gamut Volume of Ink Jet Prints using Simple Post-Processing

We describe a novel coating process for preserving and enhancing color images from ink jet prints. It involves stabilizing the printed image, followed by selective chemical interaction with the inks. The coating provides liquid, gas and UV light protection. It also changes the way light interacts with the original colorants. Untrained viewers (e.g. ordinary consumers) report the coated images appear more photographic than the original ink jet image. They prefer these images to the originals by a wide margin and report that they would pay up to 1.00 per print for them. They describe the colors as more luminous and vibrant. To better understand the reaction of these people we have conducted a small study of the spectral properties of the treated images using standard color calibration prints as test samples. Measurements of the treated samples and their comparisons with untreated samples show the method's ability to enlarge the gamut's volume up to at least the double size of the initial color gamut volume.
