An inkjet printer is different from a laser printer. It can not only print documents but also print color pictures. Because of its convenience and versatility, it has become one of the indispensable helpers in our daily life. Although most people use inkjet printers, people don't know much about their consumables ink. It has two kinds of inks, namely "dye ink" and "pigment ink". What are dye ink and pigment ink? What is the difference between the two inks? How should we choose in daily use? Let's unveil the mystery of the two inks.

Different ink compositions result in different performance

Dye ink is composed of single molecules with specific chemical structures, and the smallest unit is only 1-2 nm. The colorant of dye ink is a dye dissolved in water or organic solvent, and the dye molecules are completely dissolved in the solution. Ink is a transparent liquid. It can maintain a wide range of color gamut, realize rich and bright colors, and have excellent and outstanding image quality. Pigment ink is an aggregate composed of molecules, and the minimum pigment unit is 50-200 nm. The colorant of pigment ink is a pigment insoluble in water, which is suspended in water with the help of dispersant and is an opaque liquid. It can provide bright and bright colors, clear and sharp black, and outstanding durability, including waterproof, anti-fading, long storage time, preventing printing blockage, extending the service life of the print head, etc.

Comparison of various performances

1. Waterproof performance

The colorant in the dye ink is completely dissolved in the ink in the form of a single molecule. The colorant particles are small and easy to dissolve in water, fire and other chemical solvents, making the dye ink not easy to block the nozzle and printing smooth. However, when the print meets water, the colorant fixed on the medium will dissolve again, which may cause ink bleeding. The pigment ink adopts a multi-functional special polymer adhesive, so that the pigment has strong adhesion, and the inkjet of the print head is stable and not blocked. After the ink dries, the adhesive will form a durable protective film on the surface of the pigment, which can effectively waterproof.

1. Fade resistance

The colorant of the dye ink is directly exposed to the air. Under the action of light and ozone, the chemical chain of the dye colorant may break, causing the colorant to change color and other phenomena, so that the printed copy will fade, thus affecting its preservation performance. The colorants of pigment inks are generally highly crushed minerals with high stability. In addition, the outer layer of colorants is wrapped with a resin layer, which is not easy to fade.

From the above, we can draw the following conclusion: pigment ink has more advantages in waterproofing and anti-fading. However, in terms of bright colors and smooth printing, dye ink performs better and is cheaper. If you need to keep documents and pictures for years, choose pigment ink. If the information used is only temporary, dye ink can be used, with low cost and good color.
