Since the beginning of the 21st century, various technologies have developed rapidly, and the trend of energy conservation, low carbon, environmental protection and sustainable development has become increasingly prominent. As the main medium of color, the green process of ink is also attracting attention.
The increasingly stringent requirements of society for safety and health indicators in various industries have led to further improvement in the environmental affinity of inks, mainly in three aspects. First of all, the selection of ink raw materials is more stringent. From the earlier control requirements for six heavy metals, to the subsequent introduction of REACH and ROSH regulations, the EU's control of benzophenones, it can be said that the ink industry has experienced raw materials. From restricted use to unusable to useless.
Secondly, the ability to control residual substances and migration substances after drying the ink is improved. With the shortening of the delivery cycle of the printing and packaging industry, there are more and more short, frequent and fast printing businesses. How to achieve rapid and sufficient drying of ink in a short printing cycle? How to achieve low residue and low migration of harmful substances in ink under the condition that the health monitoring means is more and more advanced and the requirements are getting higher and higher? On the one hand, it is necessary to improve the environmental protection of the ink production process. On the other hand, it is necessary to apply more new raw materials and new technologies. For example, the use of oil-based offset inks without phenolic resin can significantly reduce the content of harmful ink residues in offset printing. Future inks will be safer, non-polluting, and edible raw materials will also find more applications in printing inks.
