China's environmental ink development history

China's environmental ink development history

In the Chinese market for environmental protection ink if in chronological order, can be divided into the following.

Solvent based ink

Environmental Friendly Soy Ink Exporter shares that ordinary solvent inks generally contain aromatic solvents (toluene, xylene). Some international ink companies are the first to introduce non-aromatic solvent ink in the Chinese market, with alcohol, ester, ether, ketone, gasoline as the solvent, eliminate the potential harm of aromatic solvent.

Currently, solvent based inks for flexographic printing are basically aromatic free, but volatile organic solvents are still abundant, which will affect the air quality of the printing shop. Residual odor in printed matter has been very few, there may be a small amount of odor in composite printed matter, but the surface of printed matter can not be found.

Water - based ink and solvent - based ink, its environmental performance is a step forward. It not only does not contain aromatic hydrocarbon solvent, and VOC also reduced greatly, but still cannot achieve 0 content, still contain a few alcohol, ether, even organic amine kind. It has less impact on the environment, mainly due to air pollution in the workshop.

UV ink

UV offsctdruckereien inks do not contain volatile organic compounds, from this point of view into a big step, more secure than water-based inks. But its drying is done by ultraviolet light. Ultraviolet light can cause skin cancer and can turn oxygen into ozone. Therefore, the drying device of the printing machine should be installed with exhaust equipment to discharge ozone out of the room. Water-based UV ink and water-based ink, there will be a small amount of volatile organic solvents, compared to ordinary UV offset printing ink, its environmental performance is worse.

In fact, the definition of environmental ink is only relative, but for the largest amount of offset printing ink, environmental ink to environmental protection has not stopped.
