Patent number: 10919334Abstract: An anti-counterfeiting pattern having an optically variable structure, comprising lithographic lines and gravure blind embossed relief lines printed on a carrier. The lithographic lines are a set of lithographic curve lines having a curvature, the widths of the lithographic curve lines changing from thick to thin, or thin to thick. The gravure blind embossed relief lines are a set of curve lines corresponding to the lithographic lines, and having the same curvature. The relief lines are overprinted on the lithographic lines with a width variation identical to that of said lithographic lines. Accurate overprinting of the two printing types forms a curved relief structure wherein the width of the lines changes continuously. When a printed product is rotated and observed, a continuously variable optical effect will be seen, which is visual, readily to identify, anti-copying and difficult to forgery.Type: GrantFiled: December 29, 2018Date of Patent: February 16, 2021Assignees: CHINA BANKNOTE INK CO., LTD., CHINA BANKNOTE PRINTING AND MINTING CORPORATIONInventors: Xing Zhang, Qingfei Meng, Yong Zhang, Xiaoquan Zhou, Guolin Yuan, Shifan Zhang
