However, The product counterfeiting has become rampant behavior in the same time. The majority of manufacturers suffered huge losses. The reputation of manufactures suffered an unprecedented challenge. In order to protect the legal rights and interests of enterprises and consumers, manufacturers take many kinds of anti-counterfeiting technology. Counterfeiting ink is one of the most important means. Anti-counterfeiting technology is a traditional anti-counterfeiting method. This study had consult a large amount of literature, with two kinds of photoluminescence powder, including common photoluminescence powder and a new style long afterglow photoluminescence powder as the pigment, then blend some UV vincula and other assistant material and so on, preparation a photoluminescence anti-counterfeiting ink sample. After the preparation accomplish, we will have professional test of the ink sample, then know the connection of material to main performance, and based with this information, we ensured the appropriate composition rate of the photoluminescence ink. This study also put the ink to printing to test the practicality. This ink take screen print for application for test .We using a variety of general and specialty papers, combine with printing materials, not only increased the difficulty of counterfeiting, but also let the anti-counterfeiting ink have more manner for use, and get a better anti-counterfeiting effectiveness.
