The objective of this paper is to integrate lenticular lens with switching images and embedding the infrared watermark to provide value-added and anti-counterfeiting features. Digital halftoning technique has been used to compose animated graphics and the infrared watermark. The infrared watermark consists of halftone dots in cyan, magenta, yellow, and black inks. The carbon material in black ink absorbs the infrared light and the watermark could be displayed under infrared detection. By using the lenticular lens, image-switching effect can be observed from different viewing angles. The results show that it is successful to implement a lenticular display with both image-switching feature and hidden watermark which can be decoded under infrared detection. The proposed method has many potential applications to anti-counterfeiting and brand protection.
