Paper given at Session 7: Spectral Imaging [7241-32].udWith the development of digital printing technologies, increasing number of primaries are adopted in colour reproduction systems aiming to improve the quality of the print, in particular, to achieve larger colour gamut, better colour constancy, and smoother colour transition. This introduces a huge challenge to the existing device characterisation techniques, e.g. for the task of calculating the colour gamut of an 11-ink printer alone, things may become mission impossible according to literature.1 This paper aims to address the issue from an artist's point of view, which reveals the fundamentals of the colour gamut of a given medium. The solution is interestingly simple that the empirical method of measuring printed colours for colour gamut calculation remains to be practical and efficient for N-ink printing system characterisation.
