Green offset inks are mainly aromatic-free soy inks. The PAH (polycyclic aromatic hydrocarbons) contained in the traditional ink composition is a volatile solvent printing film that is harmful to the human body; the volatile organic compounds contained therein not only increase atmospheric pollution, but also cause harm to the human body. Offset soybean ink uses soybean environmental protection materials instead of some petroleum solvents, which can reduce environmental pollution and human injury. The AFSOY sheet-fed offset inks, rotary inks, and thermoset-type rotary inks produced by Tianjin Toyo Ink Co., Ltd. have both good printability, environmental protection, and corresponding environmental certification. Domestic Offset Printing Ink Market Status In recent years, with the development of China's printing industry, the development of the domestic ink industry is also accelerating. With the large number of imported and domestic high-speed offset presses being installed and put into use, the use of new printing materials, and the special requirements for new printing processes and post-press processing, ink manufacturers rely on scientific and technological progress to continuously develop new products that are marketable and improve their products. The product variety has become more and more abundant, and the product quality has gradually approached the international advanced level. The renewal of ink production equipment and the improvement of production process technology have also been increasingly valued by ink manufacturers. In the past 10 years, major domestic ink manufacturers in Tianjin, Shanghai, Hangzhou, Shenzhen, and Taiyuan have continuously developed new types of offset printing ink products that meet market demands, such as bright fast drying ink, cardboard ink, and matt powder ink (no light The output of paper ink, news transfer ink, cold-set offset transfer ink, UV ink, offset synthetic paper ink, iron printing ink, and newly introduced thermoset offset transfer ink in recent years have increased year by year, and the quality is close to international The advanced level has been recognized by printing customers at home and abroad. In addition to replacing the high-grade offset printing inks imported in the past in the domestic market, some domestic offset printing ink products have also entered the international market. Some high value-added special offset inks have also been successfully developed to meet the requirements of special printing. Sheetfed offset printing inks have been steadily rising in the domestic printing market. With the innovation and improvement of printing presses, domestic sheetfed offset printing inks have been adapted to high speed, multicolor, fast drying, high efficiency, and energy saving. Demand, continuous development of new products, expanding the application in the field of packaging and printing, such as tobacco and alcohol, food, cosmetics and other industries, to meet the book printing "high light, high concentration" and packaging printing "fast-drying and friction resistance" The performance requirements; web offset inks are also adapted to the rapidly growing demand for newspapers and commercial printing, continuously improving quality levels and yields.

Environmentally friendly offset printing inks have attracted wide attention from users and have begun to be applied to packaging, newspapers, Commercial printing. Environmental offset printing ink has been applied in large scale in the United States, Japan, and other countries, but there are still few applications in the country. Among these are technical factors, but the main reason is lack of understanding.
