Abstract

A gamut boundary test chart can be used to define the gamut of a colour reproduction system as a set of vertices and triangular faces. This makes it possible to analyse characteristics of a reproduction system gamut, such as its volume. A standard chart is currently defined only for RGB and CMYK colour spaces, but the increased adoption of extended colour gamut printing requires a different approach. Here a new test chart is proposed that extends the colour spaces to include extended-gamut printing, with up to seven colorants.
