Pigment-based inks
Pigment-based inks are composed of tiny granules of pigment powder that do not dissolve completely in solution, unlike dye-based inks. This characteristic allows pigment-based inks to leave particles of pure color bonded to the surface of the paper. As a result, the images printed with these inks appear rich and physical, with densely saturated colors. However, the extremely fine detail may be slightly compromised due to the nature of the pigment particles.
Pigment-based inks are significantly more resistant to UV light compared to dye-based inks, a quality that originally made them suitable for outdoor use. They maintain their original colors for a longer period and are less likely to run if exposed to water. When printed with archival pigment-based inks on archival paper, as is the case with all of Eyestorm’s pigment-based ink prints, the images can last for at least 150 years if stored under proper conditions.
