Embodiment 1

[0054] 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.

[0055] In the second step, diluent is added to reduce the surface tension of the ink, so that the ink dot matrix can be randomly spread along the printing surface under the action of the positive wetting force, and the deformation can be enlarged (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.

[0056] In order to save the layout and not to change the version, the local area in the printing ink layer of the code can be arranged with ink dots, and the ink dots (3) can also be designed in the blank gaps i...

Embodiment 2

[0062] Such as Figure 4 As shown, on the printing surface of the printed matter with negative wetting characteristics relative to the ink, some codes formed by the ink dots with a width (ie diameter) of 0.3 mm and arranged in a dot matrix are printed.

[0063] In the second step, a tension regulator is added to enhance the surface tension of the ink, so that the ink dot matrix is ​​opened along the negative direction of the printing surface under the action of the negative wetting force, and the ink dot matrix is ​​reduced into a randomly shaped ink dot matrix by deformation.

[0064] In order to be able to use some unsuitable printing materials to print printed matters, 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.

[0065] The third step is to prepare an industrial-grade optical macro lens and digital camera, zoom in and shoot (for example, 20 t...

Abstract

The invention provides an over-limit ink dot anti-counterfeiting method and a printed matter. The method comprises the steps that codes are printed, ink dot matrixes are printed on a printing surfacewith the infiltration characteristic, the ink dot matrixes are randomly opened to be changed into ink block lattices in a random shape, the ink block lattices are amplified and shot to obtain shape characteristic information of ink blocks, and the characteristic information of the ink blocks serves as an anti-counterfeiting characteristic information file; when a consumer checks the authenticity,an ink block dot matrix is shot by using a mobile phone, and the characteristic information of the ink block is matched with the anti-counterfeiting characteristic information file so as to identify the authenticity. Compared with the prior art, a short-staple printing unit is omitted, and the defects that an existing short-staple printing unit is low in printing speed, prone to plate blocking andprone to shutdown of a production line are overcome.

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...
