Along with the increasing acceleration of the industrial production of the ink, the ink production and equipment level in China is obviously improved, the yield is continuously increased, the ink varieties are continuously increased, the quality and the grade are continuously improved, and the total annual output of the ink in 2015 nationwide accounts for 80 ten thousand tons. With the increase of people's awareness of environmental protection and the rising of environmental protection call, the ink is used as a main component of green printing, the requirement on the environmental protection of the ink is increasingly enhanced, particularly, the ink is limited by laws and regulations such as heavy metal content, residual solvent content of packing materials and other VOC (volatile organic Compounds) limit standards in other relevant aspects such as food packaging, and the development of non-toxic ink is a research hotspot of the current ink. The vegetable oil is used as the solvent, the prepared ink is environment-friendly, the renewable resources can be used for replacing the non-renewable petroleum solvent, and the waste presswork is easier to deink than the traditional ink in the process of recycling. Because the vegetable oil base contains a large amount of unsaturated fatty acid, the drying speed is slow, and the application range of the vegetable oil base ink is limited.
