Water resistance, fade resistance, and color—what’s the real difference?

If you sell ink to businesses, customers usually care about one thing: will it last and will it look right? The choice between pigment and dye ink decides that.

1) Water resistance (smear-proof)

  • Pigment ink: generally more water-resistant and less likely to smear once dry

  • Dye ink: more likely to run or smear when exposed to water/high humidity

Best for: shipping labels, documents, office text.

2) Fade resistance (light/UV)

  • Pigment ink: usually better for long-term storage and light exposure

  • Dye ink: often fades faster under light/UV

Best for: archives, signage, long-keep documents.

3) Color and photo look

  • Dye ink: typically brighter, more vivid colors and smoother photo gradients

  • Pigment ink: can look slightly less “glossy” on photos but stronger on text

Best for: photos and marketing images (often dye); crisp text (often pigment).

Quick selection by use case (fast guide)

  • Office text / contracts / labels → Pigment

  • Photos / vivid color prints → Dye

  • Mixed use → choose based on what matters more: durability (pigment) or vibrancy (dye)

For distributors, the key is not only “pigment vs dye,” but consistency by batch and clear application guidance. This is why many channel partners work with ASTA’s refill ink range (dye ink and pigment ink options) together with a simple selection guide—so end users buy the right ink for the right job.

  • Is pigment ink waterproof?
    Pigment ink is usually more water-resistant after drying, but results still depend on paper and printer settings.

  • Which ink lasts longer: pigment or dye?
    Pigment ink typically fades slower under light/UV, making it better for long-term documents.

  • Which ink looks better for photos?
    Dye ink often looks more vivid with smoother gradients, especially on photo paper.

  • Can I mix pigment and dye ink?
    Mixing is not recommended unless the supplier confirms compatibility for your printer system.
