Embodiment Construction

[0040] The present invention will be further described in detail below in combination with specific embodiments.

[0041] The present invention is a method for making a hidden image for anti-counterfeiting printing, which includes making a printing carrier and making an identification film; The anti-counterfeiting information graphic is hidden at a certain position; the anti-counterfeiting information graphic is at least two or more layers of hidden images composed of a group of points and lines, and the hidden images include vector and non-vector graphics and text. The filling line layer of the hidden image area on the printing carrier, the length of the filling line is ≥ 0.5mm, the width is ≥ 0.04mm, and the line spacing is > 0mm, the filling line is a solid line or a dotted line, and the hidden image area on the printing carrier The filled dot layer is composed of implicit image dots with a diameter ≥ 0.01mm; the minimum spacing between dots is 0.01mm, and the dot angle is ...

Abstract

The invention discloses a method for manufacturing an implicit image for anti-counterfeit printing, comprising the steps of manufacturing a printing carrier and a recognition diaphragm, placing graphics and texts to be hidden at a certain position of a carrier picture and forming an implicit image area around the position, carrying out staggered shifting on outlines of the graphics and texts to be hidden on the image in the implicit image area, stacking and coining more than two layers of implicit images, carrying out plate making and printing, placing the recognition diaphragm at the implicit image area of the carrier picture and regulating the direction and the angle of the diaphragm to show the implicit image, wherein the implicit image is the more than two layers of implicit images which are formed by at least a group of points and a group of lines; the implicit image comprises vector and non-vector graphics and texts; and the implicit image area at least comprises a group of filling line layers and a group of filling dot layers. In the invention, by means of the more than two layers of implicit images which are formed by at least a group of points and a group of lines, the scanning and the copying of fake makers are fundamentally prevented and the safety performance of products is improved.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting printing, in particular to a method for making a multi-layer hidden image that uses dot and line design to prevent imitation of a multi-layer hidden image, and is suitable for product packaging, labels, and tickets , Card Printing. 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 measure...
