Problems solved by technology

In particular, it needs to be emphasized that if mobile devices are used as anti-counterfeiting identification terminals, due to the huge amount of mobile devices in social activities, the popular information coding anti-counterfeiting of banknotes, certificates, bills and other social circulation products can be realized very quickly. It cannot be surpassed by existing technologies including fluorescent anti-counterfeiting, magnetic anti-counterfeiting, and even RFID radio frequency anti-counterfeiting.

Embodiment 1

[0042] Black conductive engraving gravure ink:

[0043]

[0044]

[0045] The preparation process is as follows: weigh the materials in the above ratio into the material tank, pre-mix for 30 minutes with a disperser, and then roll the mixture in the material tank three times on a three-roll ink padding machine. The viscosity of the product is 10.1pa.s after testing. , to achieve the technical indicators of engraving gravure ink application. The ink had a resistance value of 13.6 Mohms over a 5 cm long area after printing and drying.

Embodiment 2

[0047] Red conductive engraving gravure ink:

[0048]

[0049] The preparation process is as follows: weigh the substances in the above proportions into the material barrel, pre-mix for 30 minutes with a disperser, and then roll the mixture in the material barrel three times on a three-roll ink rolling machine. The viscosity of the product is 7.3pa.s after testing. , to achieve the technical indicators of engraving gravure ink application. The ink had a resistance value of 8.3 Mohms over a 5 cm long area after printing and drying.

Embodiment 3

[0051] White conductive engraving gravure ink:

[0052]

[0053] The preparation process is as follows: weigh the materials in the above proportions into the material tank, pre-mix for 30 minutes with a disperser, and then roll the mixture in the material tank three times on a three-roll ink padding machine. The viscosity of the product is 11.5pa.s after testing. , to achieve the technical indicators of engraving gravure ink application. The ink had a resistance value of 27.1 Mohms over a 5 cm long area after printing and drying.

Abstract

The invention discloses a conductive engraving gravure ink and an anti-counterfeit document containing the ink. The components of the ink and the weight percentages of each component are as follows: conductive material: 10-40%, resin: 20-40% %, solvent: 0-10%, other solids: 20-40%, and the viscosity of the prepared ink is greater than 4pa.s. The invention combines the traditional engraving gravure ink technology and capacitive sensing technology for banknote printing, and develops a new engraving gravure ink with conductive properties, and prints the anti-counterfeiting information in different areas through the engraving gravure ink in a gravure way. Conductive layers of different thicknesses are placed on the anti-counterfeiting documents, and then the anti-counterfeiting information is matched with the touch screen surface (or capacitive fingerprint recognition device) of the mobile device through capacitive sensing, so that users carrying mobile terminals can truly realize the anti-counterfeiting at any time. Anti-counterfeiting verification of bills anywhere. The anti-counterfeiting document of the invention has good anti-counterfeiting effect and is convenient for detection.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting. In particular, it relates to an engraving gravure ink with conductivity, an anti-counterfeiting document with engraving gravure effect printed based on the ink, and a method for anti-counterfeiting inspection of the document. Background technique [0002] At present, countries all over the world are anti-counterfeiting by setting watermarks, ultraviolet fluorescence and other means on anti-counterfeiting documents, such as bills, certificates, banknotes, etc. However, from the actual application situation, although these anti-counterfeiting means have increased the cost of bill manufacturing, the huge profits of forgery make counterfeiting activities still rampant. Even those front-line public anti-counterfeiting technologies such as laser holographic anti-counterfeiting, optical color-changing features, fluorescent anti-counterfeiting, temperature-changing anti-counterfeiting, water...
