According to the American Press Association, under normal circumstances, newspaper readers often get their hands stained with ink when reading. This is because the ink on the substrate is easily rubbed off after printing with traditional ink. Compared with traditional ink, soybean ink is friction-resistant, so that newspaper readers are not troubled by black hands, and at the same time there is no bad stimulation and odor. The boiling point of soybean ink is much higher than that of petroleum volatile components, and when oil is heated by laser printer or copier, it will not volatilize and stick to paper, nor will it pollute machine parts.

Waste paper is easy to remove ink.

According to the research, it is found that soybean ink is easier to deink than ordinary ink, and the paper fiber damage is less. Generally, more than 80% of newspaper paper is recycled paper. Using this characteristic of soybean ink, waste paper is recycled with less waste and lower recycling cost, which is highly competitive in the industry. The waste soybean ink residue after deinking treatment is easy to degrade, which is beneficial to sewage treatment and control the quality of discharged water. The research of the University of WesternMichigan, which is famous for its papermaking technology in the United States, confirms this characteristic. This characteristic of soybean ink is a very favorable factor for waste paper recycling (recycled paper). Unlike petroleum-based inks, vegetable inks are non-renewable resources. For example, soybean oil contained in soybean inks is a rich resource that is sustainable and biodegradable. It can continuously provide raw materials for ink production and has good environmental protection. Using vegetable oil (such as soybean oil) to replace part of petroleum mineral oil to make ink can promote the industrial utilization of vegetable oil in various countries, expand the application scope of vegetable oil, reduce the consumption and import of non-renewable oil and save foreign exchange.

The comprehensive printing cost is low

It is found that plant ink is easier to deink than traditional ink, and the damage of paper fiber is less, and the quality of recycled paper is better. Using this characteristic of plant ink, waste paper is recycled with less waste and lower recycling cost; The waste plant ink residue after deinking treatment is easy to degrade, which is beneficial to sewage treatment and control the quality of discharged water. Soybean ink has a wide range of colors, rich and bright colors, and a small amount of ink can show the effects that a large number of traditional inks can show. In addition, because the traditional ink contains organic compounds, in order to avoid causing environmental pollution, its disposal has become a difficult problem for ink manufacturers and printing houses. However, soybean ink can be backfilled and mixed with new ink, which is not only beneficial to environmental protection, but also reduces the production cost.

Conducive to energy security

Oil, on which traditional ink depends, is a non-renewable resource, which is increasingly exhausted with a large number of uses. The energy crisis has become the biggest problem facing mankind, and many industries have turned their attention to renewable plant resources, such as biodiesel. The soybean oil in plant ink is derived from nature, which can be infinitely regenerated and biodegradable, and has unparalleled advantages in terms of resource utilization and environmental protection.
