It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In recent years, in addition to the functional demand for the goods themselves, the appearance of the packaging has become an important indicator for people to select the goods, so that good packaging design can add to the goods themselves more and more for manufacturers. In addition, as the quality of life of people improves, the artwork collection and investment markets also develop rapidly. However, because of the different discrimination ability of people for artworks and the 'elaborate' counterfeiting of speculators, the counterfeit works across the market of the artworks and the counterfeit works are inundated. This greatly impairs the rights and interests of the creator and the consumer, making the entire artwork market confusing. In the current common anti-counterfeiting means, anti-counterfeiting marks such as safety lines, two-dimensional codes and the like are difficult to fit with the appearances of commodities, particularly artworks; the requirement for binding the watermark paper is high, and different watermark patterns need to be designed with different printing rollers, so that the individuation of the artwork is hindered; the anti-counterfeit label often can shield the details of the commodity or damage the painting and calligraphy artworks.
In order to solve the above problem, in this embodiment, a label-free anti-counterfeit material based on elastic stress luminescence is provided, and a specific structure is shown in fig. 1, where the label-free anti-counterfeit material includes: a luminescent material carrier 11 and an elastic stress luminescent material 12 mixed in the luminescent material carrier 11; wherein, the luminescent material carrier 11 is ink or inkpad. The elastic stress luminescent material 12 not only has the capability of direct force-light conversion, but also can repeatedly and stably emit light under the action of continuous mechanical force, and the luminous intensity is not attenuated. The elastic stress luminescent material 12 is added into ink or ink paste to obtain an anti-counterfeiting material, and the anti-counterfeiting material is hidden in the commodity outer package or the painting and calligraphy artwork creation by the traditional low-cost spin coating, screen printing, stamping and other modes, for example, the ink added with the elastic stress luminescent material is used for printing characters, patterns and the like required by the commodity outer package, and the ink paste added with the elastic stress luminescent material is used for signing in the signing area of the painting and calligraphy artwork. When anti-counterfeiting is carried out, the anti-counterfeiting area can emit obvious visible light when being touched by fingers, the anti-counterfeiting effect can be achieved without the help of external light, the design requirement of a user on the outer package of a product can be met, and the problems that the traditional anti-counterfeiting label and an anti-counterfeiting mark need to be matched with the appearance of a commodity or an artwork, and the commodity details are easily shielded or the painting artwork is damaged are solved.
Specifically, the graphite and the inkpad are various inks and inkpads sold on the market. In a specific embodiment, the graphite is water-based ink, and the inkpad is red inkpad.
