Embodiment 1

[0053] first step, such as figure 1 As shown, on the printing surface of the printed matter having wetting properties relative to the ink, some ink dot matrixes with a width (including length) of 0.06 mm formed by the ink are printed. And at least one unique code is printed for each printed matter.

[0054] In the second step, diluent is added to adjust the surface tension of the ink, so that the ink dot matrix is ​​randomly spread along the printing surface under the action of the wetting force, so as to be deformed (such as figure 2 As shown) dot matrix of ink sticks of random shape, and make the width of some ink sticks<twice the width of ink dots; wherein, the width of ink dots<the width of some ink sticks<twice the width of ink dots.

[0055] For saving the layout, for not changing the version, the local area in the coding printing ink layer can be arranged with ink dots. In this way, the ink dot matrix does not need to occupy the position on the printed matter alone, ...

Embodiment 2

[0061] Such as Figure 4 As shown, on the printing surface of the printed matter that has wetting characteristics relative to the ink, some codes formed by the ink dots with a width (ie diameter) of 0.06 mm and arranged in a dot matrix are printed.

[0062] In the second step, diluent is added to adjust the surface tension of the ink, so that the ink dot matrix is ​​randomly spread along the printing surface under the action of the wetting force, so as to deform into a randomly shaped ink dot matrix.

[0063] In order to be able to use some non-wetting printing materials to print printed matter, a partial wetting coating can be pre-printed on the printing material where the ink dot matrix is ​​located, and the ink dot matrix is ​​printed on the partial wetting coating.

[0064] The third step is to prepare an industrial-grade optical macro lens and digital camera, zoom in and shoot (for example, 20 times magnification) the dot matrix of the ink stick to collect the shape featu...

Abstract

An anti-counterfeit method for an out-of-limit ink dot and a printing matter are disclosed. The method includes printing encoding, printing ink dot matrix on the substrate surface with wetting property, randomly wetting the ink dot matrix to form the ink block lattice with random shape, enlarging and photographing the ink block lattice to obtain the shape characteristic information of the ink block, and taking the shape characteristic information of the ink block as the anti-counterfeit characteristic information file; when consumers check the authenticity, photographing the ink block dot matrix by the camera phone, and matching the shape characteristic information of the ink block with the anti-counterfeit characteristic information file to identify the authenticity. Compared with the background technology, the invention omits the short-fiber printing unit, overcomes the shortcomings of low printing speed of the current short-fiber printing unit, being easy to block the plate and easyto lead to the shutdown of the production line.

Description

technical field [0001] The invention belongs to the field of information query anti-counterfeiting technology, and specifically relates to another technical solution of "over-limit anti-counterfeiting method and product (patent authorization announcement number CN106096970B)" - over-limit ink dot anti-counterfeiting method. Background technique [0002] Chinese invention patent "over-limit anti-counterfeiting method and product (authorized announcement number CN106096970B)", "provides an over-limit anti-counterfeiting method and product, including setting over-limit points / lines formed by ultra-fine short fleece on the code, zooming in and shooting Ultra-fine linters are used to obtain file photos, and the archive photos are stored in the computer anti-counterfeiting query network system database; the public uses camera phones to take pictures of ultra-fine linters to obtain photos to be inspected, and the distribution characteristics and The width, and the distribution char...
