Pigment ink is a type of ink that uses tiny solid particles suspended in a liquid. These particles provide vibrant colors and are known for their durability and resistance to fading over time. This makes pigment ink a popular choice for printing photographs and artwork, as it maintains the quality of the image for longer periods. Unlike dye-based inks, which dissolve in liquid, pigment inks sit on top of the paper, creating a more textured finish. They are often used in professional printing and fine art applications, as well as in printers designed for high-quality output, such as those made by Epson and Canon.
