The advantages and disadvantages of water-based pigment ink are as follows:
Advantages:
1. Strong water resistance: Since the pigment particles of pigment ink are waterproof, the printed images are not easy to fade or blur even in a humid environment.
2. Good light resistance: The images printed by pigment ink can resist ultraviolet radiation, suitable for outdoor use, and the color is long-lasting.
3. Not easy to bleed: Pigment ink will not bleed when printed on ordinary paper, maintaining the printing quality.
4. Long-lasting color: The color of products printed by pigment ink can be maintained for a long time, which is suitable for long-term preservation of documents and pictures.
Disadvantages:
1. Higher cost: Compared with dye ink, the manufacturing cost of pigment ink is higher, so the selling price is also more expensive, which may be more than two to four times higher than dye ink.
2. Slightly poor color reproduction ability: Compared with dye ink, the color reproduction ability of pigment ink is slightly inferior, especially when bright color expression is required.
3. Matt surface: Since pigment ink is colored by attaching color materials to the surface of the medium, the printed images are usually not glossy, especially on smooth paper.
4. Printhead clogging is possible: Although pigment ink is less likely to cause printhead clogging than dye ink, there is still a risk of printhead clogging if the ink is not formulated properly or is not used for a long time.
In summary, water-based pigment ink is favored in many professional and industrial applications for its excellent weather resistance and durability, although it is more expensive and the color expression is slightly inferior to dye ink. Choosing the right ink type needs to be determined based on specific application needs and budget.
