The main development direction of the world ink is zero VOC ink, water-based ink, UV ink and vegetable oil ink. With the launch of a series of environmentally friendly inks such as non-aromatic hydrocarbon solvent inks (such as alcohols, ester-soluble inks), water-based inks, UV inks, and soy-based inks, ink environmental protection is gradually deepening. Future printing is undoubtedly based on digital printing. Although digital printing has reduced the number of plates, it is still inseparable from ink.
Bolet has formaldehyde-free, phenol-free, zero-emission, epoch-making green offset inks with more than 70% renewable materials.
In 2010, Bolett launched the world's epoch-making green offset inks with no formaldehyde, no phenolic, zero-emission, and more than 70% renewable materials.
Reducing emissions VOCs are the goal of environmentally friendly inks. If the definition of environmental protection is to reduce emissions of VOC, then zero VOC ink is environmentally friendly, but if the definition of environmental protection is to reduce water, it is anhydrous ink. In fact, it is the printing process that discharges multiple VOCs, not just the ink itself. Therefore, to reduce more VOC, a waterless printing process is used. The anhydrous offset printing plate comprises a lipophilic resin layer and an oil-repellent silica gel layer, the water-printed non-image portion is discharged with water, and the waterless plate is discharged with a uniform silica gel layer, and the ink is not in contact with water. To avoid emulsification. The difference between anhydrous ink and traditional ink is the difference between resin and binder. The principle of waterless printing is that the surface energy of the silicone in the non-image area of ​​the printing plate is low. If the viscosity of the ink is strong, the strength of attracting its own molecules will be higher than the affinity with the silicone. The material will have a strong ink repellent property. The advantage of waterless printing is that it does not use water bucket water when printing, and does not need alcohol bucket, which can save cost; no special printing solution is needed for printing, only ordinary water printing plate can be used, it is more environmentally friendly, and can be large Reduce the discharge of sewage and VOC; also avoid too much water so that the ink does not dry, and can save paper and reduce registration time.
In addition, the use of zero VOC inks and UV inks can also reduce emissions of VOCs. The VOC content in zero VOC inks is not zero, but less than 1%. The drying time of the zero VOC ink will be somewhat slower than that of the VOC, or some back adhesion (over the bottom) will occur. Because there is no solvent, there are many difficulties in producing ink, and the production time is longer. The water resistance on the Printing Machine is worse than that of the general ink.
The water-based ink is abbreviated as ink, which is processed by composite grinding of water-soluble resin, organic pigment, surfactant and related additives.
The main application fields of environmentally-friendly water-based inks are flexographic printing and gravure printing. Most of the two printing methods are packaging products, among which food packaging, tobacco and alcohol packaging, and children's toy packaging account for a considerable proportion.
In recent years, flexographic printing has developed rapidly in the world, and it is considered to be "a promising printing method on the earth" in developed countries in Europe and America. 95% of flexographic prints and 80% of gravure prints in the United States use ink. Flexographic printing is still in its infancy in China, and currently only accounts for about 3% of the printing field. In flexographic packaging printing, most of the domestic and foreign are printed with water-based inks. From 1995 to the end of 1998, China introduced more than 130 combined flexo printing production lines in just over a few years, distributed in more than 20 provinces and cities nationwide. There are nearly 200 narrow-width flexographic printing production lines in China, and annual water-based inks are needed. More than 10 million tons.
