Pigment dye ink is a misnomer. There's no such thing as "pigment dye" ink. Instead, inks are categorized as either dye-based or pigment-based. They use fundamentally different methods to deliver color.
Dye-Based Ink vs. Pigment-Based Ink
- Dye-based ink: Uses color substances dissolved in a liquid. Think of sugar dissolving in water. The color is absorbed into the paper.
- Pigment-based ink: Uses tiny color particles suspended in a liquid. Imagine sand mixed in water. The color sits on the surface of the paper.
The key difference highlighted in the provided reference is that dye inks dissolve, while pigment inks contain suspended particles. This difference leads to variations in properties like:
- Water resistance: Pigment inks are generally more water-resistant because the color particles are not absorbed.
- Longevity: Pigment inks often last longer due to the color particles' surface location.
- Vibrancy: Dye inks can sometimes produce more vibrant colors initially.
- Smudging: Dye inks are more prone to smudging than pigment inks.
Examples of Pigment Ink Applications
Pigment inks are commonly used in:
- High-quality printing: Especially for applications needing archival quality or water resistance.
- Fine art printing: To achieve rich, long-lasting prints.
- Outdoor signage: Where resistance to fading and weathering is critical.
