Grating anti-counterfeiting device and method based on EL film

Abstract

The invention provides a grating anti-counterfeiting device and method based on an EL film, having safe, harmless, environmentally friendly and sanitary components, which are harmless to humans and environments. The grating in the device is printed on the transparent PET film, the other side of the PET film is printed with a designed electric circuit, and the circuit is printed by transparent conductive ink, which meets the requirements of the electric circuit as well as the transparency; a special EL film is printed on the back side; the EL film can be printed in different patterns based on the requirements of an anti-counterfeit secret mark, and a power source is mounted at the position of the circuit power source; when not powered, the EL exhibits a specific color, and a stereoscopic anti-counterfeiting pattern is presented through the grating at this time; and when the EL film is energized, a white light is emitted to achieve a second anti-counterfeiting through the grating. The anti-counterfeiting method, by adding technologies such as an EL film and a transparent conductive ink on the basis of common grating anti-counterfeiting, greatly improves the anti-counterfeiting effect, and the device has low comprehensive cost, convenient production, and is suitable for mass production and use.

Description

technical field [0001] The invention relates to a grating anti-counterfeiting device and an anti-counterfeiting method based on an EL film, and belongs to the technical field of grating anti-counterfeiting, conductive ink and EL film. Background technique [0002] With the continuous development of my country's packaging and printing industry, packaging and printing materials have a very broad application prospect, and counterfeit and counterfeit products usually use counterfeit outer packaging to achieve the purpose of second-best. In this context, various anti-counterfeiting technologies have emerged. Judging from the current anti-counterfeiting technology and anti-counterfeiting market, three-dimensional printing anti-counterfeiting, lens anti-counterfeiting and laser holographic three-dimensional anti-counterfeiting technologies have been widely used in anti-counterfeiting labels and packaging of commodities. However, these three stereoscopic display anti-counterfeiting ...

AI Technical Summary

Problems solved by technology

For example: the three-dimensional anti-counterfeiting technology of lenticular grating only has horizontal parallax; the production cost of micro-lens anti-counterfeiting film is too high, and it is difficult to align the unit micro-lens and micro-image; the three-dimensional and dynamic effect of laser holographic three-dimensional anti-counterfeiting technology is not strong
