To reproduce colors in one system which differs from another system in terms of the color gamut, it is necessary to use a color gamut mapping process. This color gamut mapping is a method to translate a specific color from a medium (screen, digital camera, scanner, digital file, etc) into another system having a difference in gamut volume. There are different rendering intent options defined by the International Color Consortium [5] to use the different reproduction goals of the user [19]. Any rendering intent used to reproduce colors, includes profile engine decisions to do it, i.e. looking for color accuracy, vivid colors or pleasing reproduction of images. Using the same decisions on different profile engines, the final visual output can look different (more than one Just Noticeable Difference[16]) depending on the profile engine used and the color algorithms that they implement. Profile performance substantially depends on the profiler engine used to create them. Different profilers provide the user with varying levels of liberty to design a profile for their color management needs and preference. The motivation of this study is to rank the performance of various market leading profiler engines on the basis of different metrics designed specifically to report the performance of particular aspects of these profiles. The study helped us take valuable decisions regarding profile performance without any visual assessment to decide on the best profiler engine.

Because of clear image, bright color, high saturation of the color printing on coated paper, the ink-jet printing on coated paper catches more and more people’s eyes. In order to solve the problem of the ink-jet ink (cyan, magenta, yellow and black) on coated paper already developed out, whose yellow ink slants red and gloomy, different dyes are used to produce ink-jet ink. The inks were printed on the R-230 ink-jet printer on matt coated paper. The chromatic aberration is obtained on the basis of the colorimetric values in the ISO 12647-2:1996 eqv GB/T 17934.2-1999. It is found that the aberration of the Y79 is lower and its saturation is higher. The ink is filtered with 0.20 μm filter membrane and it can be used on ink-jet printing. The ink was used to print on the coated paper together with the previous cyan, magenta and black ink already developed out. The colorimetric values were measured and chromatic aberration and saturation is computed. The Color gamut graph of original inks and improved inks combination are made and compared to the standard of the ISO 12647-2:1996. It is found that the problems of hue unjust and gloomy color are improved compared to the previous four colors together. The cyan and magenta still stay away from perfect and it should be improved in future.
