Gamut boundary determination for a colour printer using the Face Triangulation Method

Tasks such as assessing the capabilities of a device or performing gamut mapping require the accurate estimation of device gamut boundaries in colorimetric space. We propose here a new method (which we call the Face Triangulation Method) to estimate the physical gamut boundary of a colour printer. The method has been tested on a real device, using two different paper media, and a common type of Gamut Boundary Descriptor. Given the small number of sample colours used for the estimate, and the high number of test colours employed, we conclude that the results achieved are rather good. We also indicate how to extend the Face Triangulation Method so that the boundary estimation can be further improved either locally or globally
