Pigment Ink Definition

Pigment ink is a type of ink formulated with tiny solid particles (pigments) suspended in a liquid carrier. Unlike dye-based inks, which dissolve into the carrier, pigment inks contain insoluble pigments that sit on the surface of the substrate, resulting in prints with excellent color vibrancy, durability, and water resistance.

Pigment inks are characterised by the following properties:

  • Durability: Pigment inks offer excellent lightfastness and resistance to fading, making them suitable for archival and long-lasting prints.
  • Water Resistance: Pigment inks are inherently water-resistant, making them ideal for printing applications where moisture resistance is required, such as outdoor signage and labels.
  • Color Vibrancy: Pigment inks produce prints with vibrant and saturated colors, capable of reproducing a wide color gamut and achieving accurate color rendition.
  • Print Longevity: Prints made with pigment inks are less susceptible to environmental factors such as humidity and UV exposure, ensuring long-lasting and fade-resistant results.

Pigment inks find applications in various printing applications, including:

  • Fine art and photographic prints
  • Archival documents and records
  • Outdoor signage and banners
  • Labels and packaging
  • Textile printing (with appropriate treatments)


Pigment inks are compatible with a wide range of substrates, including paper, cardstock, fabric, canvas, and specialty media. They are commonly used in inkjet printers equipped with pigment ink cartridges or bulk ink systems.
