Inkjet ink overview
1. Composition and classification of inkjet ink
The composition and function of the inkjet ink are shown in Table 1. According to the type of coloring agent, inkjet ink is mainly divided into dye-based ink and pigment-based ink. The dye-based ink has bright color, soft color and fine particles, but the light fastness is poor, and it is easy to fade and deteriorate. The color of pigment ink is although Not as bright as dye-based inks, but its color fastness can be as long as six months or even a year. Inkjet inks are mainly classified into solvent-based inks, aqueous inks, and uncoated inks and weak solvent inks developed in recent years, depending on the solvent used.
1. The principle of action of weak solvent ink
Low-solvent ink, also known as environmentally friendly solvent ink, has the English name ECO-solvent Ink, which is environmentally friendly, uncoated substrate and outdoor weather resistant. The principle of action is that the ink is transferred to the substrate through the nozzle of the micro-piezoelectric print head, wherein the solvent penetrates into the substrate, and as the solvent evaporates, the binder and the colorant in the ink are fixed on the surface of the substrate.

Transparent Sticker is one of plastic Lable sticker , the material is PVC sticker, PED sticker, has non-flammability, high strength, weather resistance and excellent geometric stability, and has strong resistance to oxidants, reducing agents and strong acids. In addition, due to its good flexibility, shrinkage and opacity, good processing and labeling performance, strong chemical resistance, strong and durable, it is suitable for long-term outdoor use.
transparent labels with important properties such as water, oil and chemical resistance. It is used for toilet products, cosmetics, electrical products, and is especially suitable for information labels for high temperature products.
Self-adhesive labels are very popular in this field, not only because they can be pasted, printed, and designed, but more importantly, electronic products need to use labels to achieve some specific effects. For example, the label has a strong texture and can work well with electrical appliances, or the label can resist corrosion and high temperature in the external environment.
