For many domestic brands of photorealistic inks, for example, how to choose the ink of many domestic brands What are the labels?
1、 Excellent stability:
The principle of inkjet ink is that organic pigments are evenly distributed in the organic solvent system. Some inferior inks only pursue low price in the selection of raw materials, the size of pigment particles is different, and the suspension system is very unstable. As time goes on and the temperature changes, stratification and precipitation will occur. Reaction to the inkjet printer will be in the ink barrel, ink cartridge, ink tube and nozzle ink chamber precipitation, commonly known as "sludge.". The direct result is that the ink supply is not smooth, the amount of ink ejected from the print head is not uniform, which affects the picture. When it is serious, the nozzle is blocked and the service life of oscillating crystal is extremely shortened, that is, the so-called burning head. Generally good inks do not need to be shaken or ultrasonically vibrated before use.
2、 Excellent light and weather resistance
Due to the long-term outdoor inkjet painting, UV, acid and alkali, sand and dust and air pollution will affect the picture. Therefore, when selecting ink, try to choose the products with light resistance Grade 7 (the highest level is 8, due to color reasons, some colors in the world can only reach the highest level 7) and weather resistance grade 5 (the highest level is 5).
3、 Quality of raw materials:
Due to the different prices and quality of raw materials, there are also great differences in quality, which have a great impact on the nozzle, such as purity, pH value, water content, impurities, etc., which will directly affect the service life of the nozzle. So high quality raw material is an important guarantee of high quality ink. It is suggested that users should not ignore the quality of raw materials while reducing the cost of ink. After all, inkjet printer ink has a great impact on the status and performance of inkjet printer.
4、 Excellent gamut performance: there are many hues in the colors of organic pigments, and various hues will produce different gamut effects. One of the main factors in choosing ink is to choose the color which can reflect the maximum color gamut and the preference of local consumers.
5、 Ink safety and environmental protection:
High quality ink is required not to be flammable and explosive, and the personal impact is reduced to the minimum. But now some inks on the market are only for the sake of low cost, and they will be banned from using benzene series solvents in the world. Although they are still used by users for the time being, with the enhancement of environmental protection awareness of the government and users, they will eventually be completely eliminated.
6、 Good usability:
Good ink in the normal process of inkjet printer, do not need to wipe frequently, clean the nozzle, this is a waste of ink, but also reduce the efficiency of inkjet printer. Even produce color difference, directly affect the quality and efficiency of inkjet printing. The above points can be used as a few reference indicators for choosing good and bad outdoor solvent ink, hoping to help you choose the right and high-quality photo machine ink.
