A method of the printed product fake-prevention bases on the digital watermark technology. Firstly, it chooses an appropriate color edition in the printed images and distills its printed points of network as the original point images. Then it chooses a constant area as the original image which the texture composes. It initializes a blank image as the same as the size and at random produces some points as the seeds which the texture composes in the center of the blank image. In succession, it produces two printed models which can separately represent 0 and 1 by the texture composed technology and the original image as the cyclostyle and utilizes the local search to actualize the asymmetric texture composition of the printed color edition. Finally, it executes the prevented fake information to the binary system order to embed it into the printed image. The invention can offer the effective proof by embedding non-obviously the distilled prevented fake information in the production packing. At the same time, it provides the stronger resisted forged ability and doesn't add the extra prevented fake cost. The consumer can distill the equipment to affirm the real of the production by the corresponding prevented fake information.
