1, environmental protection: soybean ink uses food-grade vegetable oil as the basic raw material, which is more environmentally friendly than traditional petroleum-based ink. It is a renewable resource, which reduces the dependence on non-renewable energy and produces less harmful chemicals in the process of manufacture and use.
2. Scratch resistance: Compared with other types of ink, soybean ink has better scratch resistance. When books or printed matter are rubbed, the handwriting will not be easily transferred to hands or other surfaces.
3, no irritating smell: traditional petroleum-based ink will emit a pungent smell when the temperature rises. Because of its composition characteristics, soybean ink has little smell and no obvious irritation during use.
