Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology, and in particular to an anti-counterfeiting certificate and its anti-counterfeiting film material. Background Technology

[0002] In the field of document anti-counterfeiting technology, it is necessary to apply an anti-counterfeiting pattern to the surface of certain pages of the document to increase the anti-counterfeiting strength by increasing the manufacturing difficulty. One method is to print a grating latent image on a film material. When verifying the authenticity of a document with a grating latent image, a grating sheet is required to see the latent image. Although this method improves the anti-counterfeiting strength, the need to use the grating sheet every time leads to a complicated verification process and thus low verification efficiency. Utility Model Content

[0003] In view of this, the present invention provides an anti-counterfeiting certificate and its anti-counterfeiting film material to solve the problem of low verification efficiency of existing anti-counterfeiting certificates when verifying authenticity.

[0004] To address the aforementioned problems, this invention discloses an anti-counterfeiting film material for use in anti-counterfeiting documents. The anti-counterfeiting film material comprises a transparent substrate, wherein:

[0005] A first grating image is printed at a predetermined position on the front side of the transparent substrate;

[0006] A second grating image is printed on the reverse side of the transparent substrate at a position that matches the preset position, and the first grating image and the second grating image form the same pattern;

[0007] A hidden image is also printed at the preset location.

[0008] Optionally, the transparent substrate is made of organic material or glass material.

[0009] Optionally, the thickness of the transparent substrate is 0.1 mm.

[0010] Optionally, the pattern of the first raster image includes multiple sub-patterns.

[0011] Optionally, each of the sub-images is a different region or a different layer of the first raster image.

[0012] An anti-counterfeiting certificate is also provided, wherein one or more layers of anti-counterfeiting film as described above are provided on the page of the anti-counterfeiting certificate.

[0013] As can be seen from the above technical solution, the present invention provides an anti-counterfeiting document and its anti-counterfeiting film material. This film material is applied to the anti-counterfeiting document, and its main body is a transparent substrate. A first grating image is printed at a predetermined position on the front of the transparent substrate; a second grating image is printed on the back of the transparent substrate at a position matching the predetermined position. The first and second grating images constitute a complete image. A hidden image is also printed at the predetermined position. Through the two grating images that constitute the complete image, the inspector can directly see the complete image or even the hidden image that serves as the anti-counterfeiting measure with the naked eye, without needing to use a grating sheet to verify authenticity, thereby improving inspection efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] This embodiment provides an anti-counterfeiting film material, which is used to apply to anti-counterfeiting documents such as qualification certificates, passports, and other entry and exit documents that require anti-counterfeiting functions, in order to increase the difficulty of counterfeiting the anti-counterfeiting documents. Specifically, the anti-counterfeiting film material includes a transparent substrate and grating images printed on both sides of the transparent substrate.

[0023] The transparent substrate is made of a transparent material that allows light to pass through. This transparent material can be colorless and transparent or it can be other colors. To avoid obscuring the content on the anti-counterfeiting document, a colorless and transparent substrate is generally chosen.

[0024] It is worth noting that the front and back of a transparent substrate are relative concepts; when one side is chosen as the front, the other side is the back.

[0025] like Figure 1 As shown, a first lenticular image 11 is printed on the front side of the transparent substrate 10 by printing. This first lenticular image 11 is actually part of a complete image. Figure 2 As shown, a second grating image 12 is printed on the reverse side of the transparent substrate 10, and this second grating image is another part of the complete image. Additionally, a hidden image 13 is printed at the positions of the first and second grating images, such as... Figure 3 As shown, the hidden image can be printed on either the front or back of the transparent substrate. Crucially, the positions of the first and second grating images are matched, and the two grating images constitute the complete image 100. Figure 4 As shown.

[0026] When the human eye views this anti-counterfeiting film, the film simultaneously reflects the first and second grating images into the eye, where they are superimposed on the retina to form a complete image 100 including both the first and second grating images. The first and second grating images have an optical path difference equal to the thickness of the transparent substrate. Furthermore, when the human eye is at a certain angle, the hidden image will become visible, such as... Figure 5 As shown.

[0027] This embodiment provides an anti-counterfeiting film material for use in anti-counterfeiting documents. The main body is a transparent substrate. A first grating image is printed at at least one preset position on the front of the transparent substrate; a second grating image is printed on the back of the transparent substrate at a position matching the preset position. The first and second grating images constitute a complete image. Through the two grating images forming the complete image, inspectors can directly see the same anti-counterfeiting pattern with the naked eye, without needing to use a grating sheet to verify authenticity, thereby improving inspection efficiency.

[0028] In this embodiment, the transparent substrate can be a transparent film material made of organic materials such as PC or PVC, or it can be based on tempered glass. The thickness of the transparent substrate is preferably 0.1 mm. This thickness matches the parameters of the first and second grating images, allowing for better image reflection.

[0029] The first and second grating images are printed on the front and back sides of the transparent substrate using UV ink.

[0030] In addition, it is worth noting that the purpose of this application in achieving the invention objective by using a grating image does not lie in its specific pattern, but in the specific size parameters of the dot and line blocks that constitute the grating image. Under this premise, the grating image can be an animal image, a plant image, or text. This application does not require the content of the image.

[0031] Example 2

[0032] This embodiment provides an anti-counterfeiting certificate, on which some or all pages are provided with the anti-counterfeiting film provided in the previous embodiment. In order to better achieve the anti-counterfeiting effect, one or more layers of the anti-counterfeiting film can be provided on the corresponding pages.

[0033] The main body of the film material is a transparent substrate. A first grating image is printed at least one preset position on the front of the transparent substrate; a second grating image is printed on the back of the transparent substrate at a position matching the preset position. The first and second grating images constitute a complete image. A hidden image is also printed at the preset position. Through the two grating images that constitute the complete image, inspectors can directly see the complete image or even the hidden image that serves as an anti-counterfeiting measure with the naked eye, without needing to use a grating sheet to verify authenticity, thereby improving inspection efficiency.
