The foundation of fine art inkjet printing is long-term stability. Prints should last not for a few years, but for several decades. This durability begins with pigment ink. Pigment inks contain tiny solid particles suspended in liquid, which makes them far more resistant to light and environmental influences than dye-based inks.
Testing by Wilhelm Imaging Research shows that certain pigment ink systems can maintain accurate colours for more than a century under suitable conditions. Macworld’s technical review of ink types reaches the same conclusion and confirms that pigment inks fade significantly less under normal lighting.
