Ink is usually composed of pigments, binders, solvents and additives, and these components often contain many toxic or harmful substances. Such as benzene (including benzene, toluene, xylene, etc. ) is listed as a carcinogen by the World Health Organization.

There are also heavy metals such as lead, chromium and mercury in pigments and aromatic hydrocarbons in petroleum solvents, which will pose a threat to human health and the natural environment.

Extended data

The price of environmentally friendly ink is much higher than that of ordinary ink. The only environmentally friendly ink that can be used for commercial printing is UV ink, but the dosage is also relatively small. In the packaging and decoration industry, due to the large amount of packaging and printing, there are certain requirements for environmental protection, so the amount and opportunities of using green ink are relatively large.

In addition, the use of green ink also has special requirements for equipment, accessories and consumables. For example, cots should be specially made or dual-purpose, and these accessories are more expensive, which will increase the cost of enterprises.
