Anti-counterfeiting mark, manufacturing process and production line

The invention discloses an anti-counterfeiting mark, a manufacturing process and a production line, in the manufacturing process of the anti-counterfeiting mark, firstly, a printing layer with random patterns is printed on a product, and the printing layer has multiple colors which are randomly distributed; and then gold stamping treatment is conducted on the printing layer, so that a gold stamping layer is formed in the area, where a preset color is located, of the printing layer, and the printing layer and the gold stamping layer jointly form the anti-counterfeiting mark. Due to the fact that the anti-counterfeiting mark is provided with the gold stamping layer, the anti-counterfeiting mark is difficult to copy through a conventional printing means, and due to the fact that the gold stamping layer is located in the area where the preset color is located on the printing layer, the gold stamping layer is of a specific structure, and the imitation difficulty of the gold stamping layer is improved. Furthermore,
