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.
