Pigment Particles and Their Effect on the Colour Gamut of Printing

摘要

This paper is concerned with changes in the colour gamut when overprinting a substrate with colour ink layers. The deviations of the resulting colour are dependent on the thickness, size and colour of pigment particles and their volume concentration. If the colour ink layers are sufficiently thin then it is shown that the substrate also influences the final result. All the pigment particles are non-transparent and the effect of spectral reflectances are also considered.
