In printing consumables, ink is mainly divided into dye-based ink and pigment-based ink. They differ significantly in composition, applicable scenarios, and printing effects.

1. Composition Differences
Dye-based ink: The pigment in the ink is completely dissolved in water or solvent. Its molecules are small and can penetrate into the paper fibers.

Pigment-based ink: The pigment in the ink is suspended in the liquid as tiny particles. It does not dissolve and can adhere to the paper surface.

2. Printing Effects
Dye-based ink: Vibrant colors and natural transitions, suitable for photo printing and high-saturation images.

Pigment-based ink: Water and light resistant, with clear text edges, suitable for document printing and long-term preservation.

3. Suitable Paper
Dye-based ink requires paper with good absorbency; otherwise, it is prone to smudging.

Pigment-based ink is more adaptable to different paper types and maintains clarity even on non-absorbent paper.

4. Durability
Dye-based ink has vibrant colors but weaker water and light resistance.

Pigment inks offer high durability, making them suitable for long-term document archiving or outdoor labels.

Ink type selection should be based on printing needs: dye-based inks are preferred for photo printing, while pigment inks are preferred for documents and long-term archiving.
