"Prints printed on soy inks also have good abrasion resistance, and prints will not rub and fade. When printed matter printed with soy ink is discarded, the recycled waste paper is easily deinked, and good quality recycled paper can be produced."
It is understood that organic pigments used in soy inks do not contain harmful metal elements such as lead, chromium, cadmium, mercury, arsenic, antimony, etc., which greatly improves the health and safety of the ink. What is more important is to replace most or all petroleum-based mineral oils with soybean oil, minimizing the environmental pollution caused by volatile organic compounds (VOCs) and harming human health.
