Performance difference and selection skills between pigment ink and dye ink

I don't know because the manufacturer's propaganda is because the pigment ink is more expensive than the dye ink. Many users think that pigment ink is better than dye ink when they choose ink to add ink to their expensive ink cartridges. In fact, pigment inks and dye inks have their own strengths, and it cannot be said that who is better than anyone else. For users who use nozzle cartridges, adding dye ink is a more suitable choice.

why? First we need to distinguish between what is pigment ink and what is dye ink.

1 pigment ink

Pigment inks are a collection of molecules whose smallest unit is much larger than the molecular diameter of dye inks, ranging from 50 to 200 nanometers, usually in the form of opaque liquids. Pigment ink is a bit of an image, which is powdery ink. Of course, this is just an image and it is not accurate enough. To be precise, it is a solid pigment that is ground into very fine particles and dissolved in a special aqueous solvent. It is a suspension solution or a semi-solution, which is the same as the pigment of our dyed clothing. Contrary to the principle that the dye ink penetrates into the medium to form a color, it is colored by the color material attached to the surface of a medium such as copy paper or printing paper. Therefore, under the influence of external corrosion, only the outermost molecular structure will be destroyed first, and the structure inside will not be easily damaged. After the outer layer of molecules is destroyed, fading will occur. For the printing color, due to the polymer of the outer layer of the pigment ink, it can not display the color color and vividness of the color well, even if it is printed on paper with flat surface such as glossy paper, it can not print glossy. The image comes, which is why the things printed with pigment inks are generally dull.

Advantages: waterproof and light resistant.

Disadvantages: Large particles, it is easy to cause plugging, the printed image is not good color, not bright.

2 dye ink

Dye ink is a molecular-level fully soluble ink, generally 1~2 nanometers in diameter. Danjun consumables INKOOL brand carbon-collar technology inks will have a diameter close to zero; this ink is a complete composite solution, the probability of blocking the ink head It is very small, easy to be absorbed by materials after printing, and printed on smooth and smooth paper, which performs well on light emission, so the color reproduction ability is strong, the printed image is colorful, and the cost is low; Dye inks are not protected by a layer of polymer on the surface like pigment inks, so under harsh conditions, molecules are easily broken down, causing fading.

Advantages: The nozzle is not blocked, and the printing is bright and colorful.

Disadvantages: It is easy to fade when it is directly exposed to sunlight or soaked in water.

●How to choose

After introducing the characteristics of the two inks, let's analyze how the traders who use the ink cartridges with the nozzles should choose when adding ink.

First of all, we need to consider the maintenance of the nozzle, the use of pigment ink, the probability of nozzle clogging will be much larger than the use of dye ink, which is very likely to cause the user who wants to use ink to reduce costs Cost

Secondly, in terms of printing pictures, dye ink has obvious advantages in color expression than pigment ink. Personally, if the period of use of pictures is not long, bright colors are more valuable than dim!

Again, the problem that the dye ink can not be waterproof can be solved by other methods, such as applying a layer of transparent glue on the picture, or directly over-molding (generally available in a print shop or photo processing shop), as well as Waterproof and stored for a long time.

Therefore, dye ink is the best choice for users who add ink. However, it is necessary to remind everyone that the quality of dye ink on the market is also uneven. Choosing good dye ink is the protection. Your ink cartridges and printers get better image color and more economical!
