What are the differences between dye ink and pigment ink?

As we all know, the sublimation ink is a kind of water-based dye ink which is different from the pigment ink.Dye ink is applied in sublimation printing mostly,while pigment ink is largely employed in photo industry.

The difference between them is bellowed:

ink

Dye ink has good ability of color reproduction, but poorer waterproof, light resistance, oxidation resistance on the paper, when photo after long-term preservation, it prone to fade. So dye sublimation ink is often used with the help of sublimation paper. When transferred on the materials with temperature and pressure, the color with be so fasten onto the fabric.

While the properties of the pigment ink is much different from the due ink,, on the other hand, It is widely used in photo industry for its good waterproof, light resistance, oxidation resistance and save- performance, only color reproduction ability will become slightly worse.

Why there are so big difference? This should be explained from its structure.

In the dye ink ,colorant is completely dissolved in the ink by single molecule way for its stain particles is small and easy to dissolve in water or other chemical solvent. This structure makes the dye ink is not easy to cause nozzle. clogging.Even congested, dredging nozzle is relatively simple. But dye colorant has a lot of water particles which makes it prone to dissolve easily. So once the typescript under water, the original fixed colorant will dissolve again in the media, and with the flow of water to spread around, causing severe shading phenomenon. This is the poor waterproof performance of dye ink. At the same time,when the dye ink stains is directly exposed to the air, under the action of light and ozone, dye colorant chemical chain may break, causing discoloration phenomenon such as typescript color fading.

The structure of the pigment ink is the same, colorants are some solid particles. In order to make these solid colorants in uniform distribution, you need to add emulsifier, making the coloring outside wrapped with a layer of special resin composition.With the help of a resin layer on a small amount of hydrophobic particles, it will make the ink in emulsification, colorants in suspension. Due to the stain does not dissolve in water, when the typescript under the influence of water ,stain is not with the water migration, so its nature of water resistance has greatly improved. And pigment ink stains are generally highly crushing of minerals, its stability is very good, plus colorants outer package resin layer, when meet such as sunshine and ozone, first of all damage is outside of the resin layer, and the internal colorants are not affected, nature is not prone to fading.
