For artists wishing to print onto heavy weight coated and uncoated papers, the opportunity to improve colour
density and saturation is always desirable. The paper presents research into methods for mixing and printing
colours using the latest multi-primary inkjet printing system. The objective is to investigate the colour
printability of the system printing on a fine art paper. The cellular Yule-Nielsen modified spectral Neugebauer
model is employed to characterise the printing process. And the preliminary experiment result shows the
effectiveness of the proposed method.
With 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.<sup>1</sup> 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.
