Analysis of the current market development trend of water-based printing inks

market trend of water-based printing inks

among volatile dry inks, water-based inks developed in the 1980s have been paid attention to because they are conducive to environmental protection. At the beginning of the development of water-based ink, it was once noticed by people, but it was not popularized because of the poor water demand of its template and the wrinkle caused by the absorption of water by the paper when printing on the paper. After entering the 1990s, the above problems have been gradually solved. With the advent of new water-based inks using urethane emulsions, their varieties are also increasing

from customers, but many people close to Zhongnanhai emphasize the analysis from the perspective. Because the function, use, price, equipment and supply of (water-based ink) are better than (UV ink), the traditional ink will slowly disappear in the printing ink market in the future, replaced by water-based ink and UV ink, and finally the water-based ink will completely occupy the market. Commercialized water-based inks have been in line with the principles of simplicity, practicality and economy. The three major shortcomings that existed in the past have now been overcome. For example:

1 The biggest disadvantage of water-based ink is that its dryness is slower than that of solvent based ink. Theoretically, the evaporation energy of water is times greater than that of oil. How to improve the dryness is a comprehensive problem. After years of research, the composition of water-based ink has been completely improved

① first, reduce the water content of water-based inks from 70% to 30%. ② It is to micronize the water-based ink, so that the water-based ink that can only be printed with 150 mesh silk can be printed with 300 mesh silk. In this way, the printing film is thinner and the drying is faster. ③ It is to reduce the viscosity of water-based ink, reduce the surface tension and promote capillary phenomenon without hindering the printing effect, so as to improve the effect of evaporative drying and osmotic drying. ④ The most important thing is to have an efficient infrared dryer. Because infrared ray is radiation energy, it has penetrability, and can directly interact with molecules in printing ink. It heats both inside and outside at the same time to promote instant drying. Now, color printing with water-based ink also includes drug controlled release materials and bone fixation materials with high technical content and high added value. Instant drying between colors takes only 5S at 150 ℃. This drying speed is almost as fast as UV printing ink

2. Water based inks have good adhesion to absorbent objects (porous objects), such as cloth (cotton, hemp, wool, silk, polyester, nylon and their blends), paper (paper, paperboard), wood (wood, wood, plywood), leather (leather, artificial leather), but it is difficult to solve the problem of insufficient plastic hardness for hard surface printing materials. Now, because the fixing agent of water-based ink is acrylic, polyester, polyester coincidence resin, its all-round bonding function has excellent adhesion to non absorbent substrate, substrate with smooth and hard surface, and objects that used to be difficult to follow. Such as water repellent cloth, synthetic paper, thick canvas, rigid PVC, PVC, stickers, PVC cloth, artificial leather, acrylic, ABS, as, pet, PS, glass, hard aluminum foil, stainless steel, etc

3. The problem of full hydration of water-based inks

although water-based inks in the past have been watered, most of them add 10% - 15% solvent in order to improve the softness, brightness and prevent infiltration of inks. Now the water-based printing ink can overcome the above problems, which is all water-based printing ink

the development of water-based printing ink has become a hot topic in the silk printing industry. Because the state has regulations on environmental protection, printing practitioners have awakened themselves and have refused to use solvent based printing ink for their own health and switched to water-based printing ink. The neighbors of the printing factory will notify the environmental protection department as soon as there is a little peculiar smell; For orders received from export traders such as toys, clothing, furniture, curtains, etc., it is often stated that non-toxic printing ink processing should be used to ensure the full range of experimental power; When purchasing T-shirts, consumers also learn to touch them with their hands to see whether they are printed with water-based ink. Customers should also ask whether they are printed with water-based ink when subscribing. Another reason is that all prepress can be processed by computer. From design, text, pattern, combination to four-color film output, the urgent parts can be delivered in one hour, the plate making (four-color plate) can be picked up on the same day, and the high-efficiency four-color printer and high-efficiency infrared instant dryer are available, creating conditions for the use of water-based ink
