Non-VOC ink mark

This is an environmental mark that can be given to printing inks in which high-boiling-point petroleum solvents in the ink components are replaced with recycled vegetable oils, etc., and the heating subtraction method is reduced to less than 1% under Method 24's measurement conditions. It is an environmentally friendly ink that is more advanced than vegetable oil ink. The mark can also be used for printed materials printed with applicable inks.
*VOCs (Volatile Organic Compounds) are one of the substances that cause photochemical smog due to photochemical reactions in the atmosphere.
