Embodiment 1

[0047] like figure 1 As shown, a method for detecting the ink release performance of the anti-counterfeiting label covering layer, the

[0048] Methods include:

[0049] Preparatory work before the test, firstly preheat the monitoring instrument of this application to the specified temperature, and cut the paper to the same size as the anti-counterfeiting label to be tested, so that the paper is cut to the same size as the anti-counterfeiting label to be tested, The size of the anti-counterfeit mark to be tested is smaller than that of the heat-resistant glass plate, so that the heat-resistant glass plate can completely cover the anti-counterfeit mark.

[0050] Step S1: Adsorb the paper soaked with alcohol solvent on the upper surface and / or lower surface of the anti-counterfeiting mark to be tested.

[0051] Step S1 includes:

[0052] S101: The automatic liquid adding device drips the alcohol solvent onto the paper to wet the paper with the alcohol solvent, and the alcohol...

Embodiment 2

[0074] An ink precipitation performance testing instrument for the cover layer of an anti-counterfeit mark, comprising: an opening and closing gland, a heating device, an image acquisition device, and a data analysis and processing module; The paper soaked with the alcohol solvent is adsorbed on the upper surface and / or the lower surface of the anti-counterfeiting mark to be tested. like figure 2 and image 3 As shown, the opening and closing gland includes an upper gland 1 and a lower gland 2. The upper gland 1 is arranged in parallel above the lower gland 2, and one end of the upper gland 1 and the lower gland 2 is connected by a rotating member 5, and the other end is separated. When the upper gland 1 is opened, the upper gland 1 rises to a certain height relative to the lower gland 2, so that an anti-counterfeit mark to be detected can be placed between the upper gland 1 and the lower gland 2.

[0075] In this application, the upper and lower surfaces of the anti-count...

Abstract

The invention provides a method and apparatus for detecting the ink deposition performance of an anti-counterfeit mark cover layer. The method comprises the steps that S1 paper impregnated with an alcohol solvent is adsorbed on the upper surface and / or the lower surface of an anti-counterfeit mark to be tested; S2 the heating temperature of the paper is preset, and the wetted paper is heated until the paper is dry; S3 the ink trace image of the paper in a dry state is collected; and S4 the ink deposition performance of the anti-counterfeit mark is analyzed according to the collected ink trace image. According to the invention, the paper impregnated with the alcohol solvent is adsorbed on the upper and lower surfaces of the anti-counterfeit mark; and according to the mutual solubility of ink and the alcohol solvent and the extent to which the ink covered by the inner cover layer of the anti-counterfeit mark is dissolved by the alcohol solvent, the confidentiality and security of the anti-counterfeit mark cover layer is judged.

Description

technical field [0001] The present application relates to the field of anti-counterfeiting technology, in particular to a method and an instrument for detecting ink release performance of an anti-counterfeiting label covering layer. Background technique [0002] At present, the scratch-off anti-counterfeiting mark is a kind of anti-counterfeiting product. The scratch-off type means that the surface of the mark is printed with an ink layer. The ink layer is used to display the winning information or symbol code. It is used to cover the outer surface of the ink layer, so as to strengthen the protection of product safety performance. The ink layer is formed by ink, and the ink and alcohol solvent can dissolve each other. The alcohol solvent itself is very volatile when preheated. Compared with the prior art It is common to use the metal heat conduction plate to heat the anti-counterfeiting mark. However, in the test, the heat conduction plate is frequently exposed to chemical r...
