The disadvantage of dye ink is that it is not waterproof, and because the dye molecules decompose quickly under ultraviolet radiation, it will obviously fade within one month after being used outdoors under ultraviolet radiation.
The disadvantage is that most pigment inks will cause residual color materials on the surface. Therefore, even printing on glossy paper and other paper with flat surface cannot print glossy images, which is why things printed with pigment inks generally have no luster. In addition, the manufacturing cost of pigment ink is higher, so the selling price is also higher than that of dye ink, and the price difference is more than two to four times.
