Problems solved by technology

The disadvantages of printing polarized test pieces are: it needs to be covered with a fuzzy layer to eliminate printing marks; the production process is complicated and the cost is high; the price of transparent ink containing polarizing medium powder is high and it is not easy to buy
The process is more complicated and the cost is too high

Embodiment 1

[0054] Polarized invisible images were prepared in the following manner:

[0055] (1) PC film is used as the first printing layer;

[0056] (2) Use ordinary ink to print colored patterns on the PC film, and reserve an invisible image area;

[0057] (3) It is synthesized from PE stretch film, that is, it is made into an invisible image carrier;

[0058](4) Use a hot stamping machine to make the desired hidden pattern in the invisible image area by heating and embossing;

[0059] (5) Composite the invisible image carrier after heating embossing treatment to the polarizer;

[0060] (6) Paste the silver polyester reflective layer on the polarizer to make a polarized invisible image.

[0061] The prepared polarized contact image is used in the test of polarized sunglasses to achieve the effect of distinguishing the authenticity of the glasses.

Embodiment 2

[0063] Polarized invisible images were prepared in the following manner:

[0064] (1) PC material is used as the first printing layer;

[0065] (2) Use ordinary ink to print colored patterns on PC materials, and reserve invisible image areas;

[0066] (3) Then take PVC stretch film and synthesize it, that is, make it into an invisible image carrier;

[0067] (4) Use a hot stamping machine to make hidden patterns such as company logo patterns in the invisible image area by heating and embossing;

[0068] (5) Then the invisible image carrier after heating embossing treatment is compounded to the polarizer;

[0069] (6) Finally, the reflective layer of silver paste is printed on the polarizer to make a polarized invisible image.

[0070] The prepared polarized invisible image is made into an invisible label, which is pasted on the outer wall of the packaging box for anti-counterfeiting, and the effect is good.

Embodiment 3

[0072] Polarized invisible images were prepared in the following manner:

[0073] (1) PC material is used as the first printing layer;

[0074] (2) Use ordinary ink to print colored patterns on PC materials, and reserve invisible image areas;

[0075] (3) Then take the PP stretch film and synthesize it, that is, make it into an invisible image carrier;

[0076] (4) Use a hot stamping machine to make hidden patterns such as company logo patterns in the invisible image area by heating and embossing;

[0077] (5) Then the invisible image carrier after heating embossing treatment is compounded to the polarizing film;

[0078] (6) Finally, the reflective layer of silver paste is printed on the polarizing film to make a polarized invisible image.

[0079] The prepared polarized invisible image can be used as a test for polarized sunglasses, and good results can be achieved.

Abstract

The invention relates to a polarization concealed image and a preparing method thereof. The method comprises first providing a winding film to serve as a carrier for the concealed image, then obtaining a pattern required to be concealed on the carrier for the concealed image through a heating and press printing method, further compositing the carrier for the concealed image after heating and press printing treatment onto a polarization material, lastly compositing a reflection layer onto one face of the polarization material without the carrier for the concealed image, and obtaining the polarization concealed image.

Description

technical field [0001] The invention relates to the application field of polarized light, in particular to a polarized invisible image and a preparation method thereof, which are used for product anti-counterfeiting, polarized product detection and the like. Background technique [0002] Polarized light is the light in which the direction of the light vector of the light wave does not change, but its magnitude changes with the phase. When light passes through different media, it will be refracted at different angles. When light passes through a special medium that can make it have a 90° refraction angle, the phenomenon of polarized light (also known as polarized light phenomenon) will occur; this refracted light is called polarized light; this special medium is called Polarizing medium. [0003] Polarized light (polarized light phenomenon) is a wonderful natural phenomenon that has been discovered and valued by people for a long time. Currently, polarizing properties are ...
