This research concerns the study of the effects of pigmented inkjet dispersion for use on silk fabric. The pigmented inkjet inks were formulated using two types of pigment dispersion techniques: surface modification and micro-encapsulation. Properties of both inks are: viscosity 3.5-5 mPa s, surface tension 38-45 mN m⁻¹, and particle size 0.22-0.23 μm. The stability of the inks was examined for changes in viscosity and particle size distribution. The inks were stored at ambient room temperatures for 12 weeks. After storage, the inks viscosity was increased by 20-40% and the particle size by 2-15%. The printed silk fabric was analyzed here only for tone reproduction and color. The surface modified pigmented inks yielded high optical density, good tone reproduction, better color gamut, and gamut volume. This research explains the influences to cause such results.
