Processing method of anti-counterfeiting printed products

Abstract

The invention discloses a processing method of anti-counterfeiting printed products. The processing method comprises the following steps of 1 adopting optically variable ink to print base patterns on a base material; 2 designing concave-convex embossing patterns of intaglio and letterpress layouts, wherein outlines of the concave-convex embossing patterns are smaller than those of the base patterns; 3 manufacturing the intaglio and letterpress plates according the concave-convex embossing patterns, wherein working contact faces of the intaglio and letterpress plates are oblique planes, and included angles formed by the oblique planes and the surface of the base material range from 1 degree to 30 degrees; 4 using an intaglio and letterpress embossing device to finish concave-convex embossing processing within an area defined by the base patterns. The processing method can show two color patterns at the same viewing angle by means of a concave-convex embossing process and by utilizing a color change characteristic of the optically variable ink. The pattern effect shown by the anti-counterfeiting printed products is easily recognized, the counterfeit processing difficulty is high, and the anti-counterfeiting security level of the products is greatly increased.

Description

technical field [0001] The invention relates to a production and processing method of two-way color development of an optical color-changing ink. The color-changing property of the optical color-changing ink presents two color patterns at the same viewing angle. Background technique [0002] With the development of the economy, the contradiction between counterfeiting (counterfeiting) and anti-counterfeiting becomes more and more acute. Because counterfeit or counterfeit goods can bring huge profits, counterfeiters take risks and conduct in-depth research on deciphering and counterfeiting methods; their counterfeiters often focus on falsification in outer packaging, labels and ticket documents, especially computer graphics processing technology, color copying, high-quality The rapid development of high-precision scanning, high-resolution printing, and digital printing technology makes the original anti-counterfeiting measures easy to lose confidentiality. Therefore, researc...
