Green printing

A considerable portion of the pigment used in the packaging material is a compound containing heavy metals and is highly toxic. In addition, the ink manufacturing process used in a variety of organic solvents, resins and other organic matter, make the packaging ink has become one of the main culprits of environmental pollution.       The nature of the color of the structure originated in the micro-nano structure, in the preparation process using environmentally friendly polymer materials, to abandon the toxic, polluting raw materials, from the essence to ensure that the product clean green and security. While the water as a medium, greatly reducing the organic volatile emissions, reducing the air pollution. In addition, the water-based media can reduce the risk of fire caused by static and flammable solvents and hidden dangers, reduce the printing surface residue, cleaning printing equipment convenient, cheap and safe, easy to operate.       Therefore, the structure of color photonic crystal material, can effectively solve the ink in the color of the pollution and safety problems.
