Optical grating material with dynamic information

The utility model relates to an optical grating material with dynamic information. The optical grating material comprises an optical grating sheet and a dynamic information anti-fake pattern layer, and the dynamic information anti-fake pattern layer is printed on the back face of the optical grating sheet. The dynamic information anti-fake pattern layer is printed on the back face of the optical grating sheet, the dynamic information anti-fake pattern layer is fused with the high-precision shade manufacturing and dynamic printing technology, the optical grating sheet is used as a carrier and a decoding tool, encrypted information specified by a client can be clearly obtained through the optical grating sheet, the strong dynamic state is achieved, the encrypted information can vertically move along with the human eyes when the human eyes swing, the amplitude is large, the dynamic state is strong, normal characters can be displayed when the optical grating sheet is bent, meanwhile, the high anti-fake function and interestingness are achieved, detection is convenient, therefore, the anti-fake effect of the dynamic information is achieved, the anti-fake function is better, heavy metal materials do not need to be adopted for printing, and are more environmentally friendly, the aim can be achieved through common printing, and the manufacturing process is simpler.
