Adjustable color transformation model

Color management is an important part of the print production process. This paper presents a color transformation model which can provide all possible four-color solutions (CMYK) for a given aimed color (CIE L*a*b*). The model also allows quick adjustments of gamut mapping and total ink limit (TIL). The tests showed that the presented model is quite accurate. The model is less accurate for colors near the gamut boundary, but there is potential for improvements. Very high accuracy was achieved by avoiding gamut boundary colors. In practice, this is useful for application to image re-separation, usually with the aim of ink saving.
