Pigment-based ink is a type of ink that uses tiny particles of color, known as pigments, suspended in a liquid. Unlike dye-based inks, which dissolve completely, pigment inks remain solid and provide more vibrant colors and better resistance to fading over time. This makes them ideal for printing photographs and artwork that need to last. One of the main advantages of pigment-based ink is its durability. It is less likely to smudge or bleed when exposed to water or UV light, making it suitable for archival purposes. Many professional printers and artists prefer pigment inks for their high-quality results and longevity.
