Pigment Ink

Pigment inks are literally pigments of colour ground down very fine and suspended in a liquid to make ink, compared to dye ink, which is a dye suspended in liquid. As with other types of colour, this produces a more lightfast material or ink that will take longer to fade. Current pigment based inks on the market can be anywhere up to 100+ years lightfast, but this depends on a number of factors such as ink manufacturer, paper type and storage conditions. Pigment inks can tend to have a smaller colour gamut than dye-based inks.
