A pigment-based ink uses solid particles of pigment powder suspended in the ink itself to transfer colour. This type of ink is more durable than dye-based inks because it resists fading for longer and doesn't smudge as much when drying. This makes it the perfect type of ink to use for documents (especially photos) that need to be kept in an archive. Pigment-based inks are perfect for printing on slicker surfaces like transparencies and stickers. However, they are more expensive than their dye-based counterparts and not as vibrant either.

Pigment inks tend to be lighter in colour than dye they are more water-resistant while producing a truer solid black than dye. Es-pecially when the label is exposed to UV light for many months, the pigment ink holds its colour, quality and vibrancy better than dye. Speaking of water resistance and long life durability plus colour consistency the winner is pigment ink.
