Embodiment 1

[0028] A latent image embossing anti-counterfeiting structure, comprising a base, and a recess formed on the surface of the base by an embossing mold. The depth of the recess is 0.01 mm; protrusions are formed between adjacent recesses, and the plurality of protrusions form an anti-counterfeiting pattern.

[0029] The preparation process of the latent image embossed anti-counterfeiting structure comprises the following steps:

[0030] (1) Prepare the bottom part: choose paper with a smooth surface.

[0031] (2) Prepare the embossing mold. The embossing mold includes regular trapezoidal convex parts arranged at intervals, and inverted trapezoidal concave parts are formed between adjacent convex parts. The upper bottom of the convex part is 0.1mm, and the height of the convex part The height is 0.08mm; the regular trapezoid is an isosceles trapezoid with a base angle of 45°; the concave part forms an anti-counterfeiting pattern, and the shorter bottom edge length of the concave ...

Embodiment 2

[0038] In this embodiment, a latent image embossing anti-counterfeiting structure includes a bottom part and a concave part formed by pressing the surface of the bottom part through an embossing mold. The depth of the concave part is 0.008 mm; convex parts are formed between adjacent concave parts, and several convex parts The part forms an anti-counterfeiting pattern.

[0039] The preparation process of the latent image embossed anti-counterfeiting structure comprises the following steps:

[0040] (1) Prepare the bottom part: choose paper with a smooth surface.

[0041] (2) Prepare the embossing mold. The embossing mold includes regular trapezoidal convex parts arranged at intervals, and inverted trapezoidal concave parts are formed between adjacent convex parts. The upper bottom of the convex part is 0.08mm, and the height of the convex part The height is 0.06mm; the positive trapezoid is an isosceles trapezoid with a base angle of 45°; the concave part forms an anti-counte...

Embodiment 3

[0047] A latent image embossing anti-counterfeiting structure, comprising a base, and a recess formed on the surface of the base by an embossing mold. The depth of the recess is 0.012 mm; protrusions are formed between adjacent recesses, and the plurality of protrusions form an anti-counterfeiting pattern.

[0048] The preparation process of the latent image embossed anti-counterfeiting structure comprises the following steps:

[0049] (1) Prepare the bottom part: choose paper with a smooth surface.

[0050] (2) Prepare the embossing mold. The embossing mold includes regular trapezoidal convex parts arranged at intervals, and inverted trapezoidal concave parts are formed between adjacent convex parts. The upper bottom of the convex part is 0.12mm, and the The height is 0.1mm; the regular trapezoid is an isosceles trapezoid with a base angle of 45°; the concave part forms an anti-counterfeiting pattern, and the shorter bottom edge length of the concave part of the inverted trap...

Abstract

The invention relates to the printing anti-fake technical field, in particular to a latent image embossing anti-fake structure and a preparation process thereof. The latent image embossing anti-fake structure comprises a bottom part and concave portions formed by pressing an embossing mold onto the surface of the bottom part, and the depths of the concave portions range from 0.008 mm to 0.012 mm.Convex portions are formed between the adjacent concave portions, and an anti-fake pattern is formed by the multiple convex portions. The embossing mold comprises right-trapezoid protruding portions arranged at intervals, inverted trapezoidal sunken portions are formed between the adjacent protruding portions, the upper bottom of each protruding portion ranges from 0.08 mm to 0.12 mm, and the height of each protruding portion ranges from 0.06 mm to 0.1 mm. Each right trapezoid is an isosceles trapezoid with the base angle being 45 degrees. Printing ink is borne on the sunken portions, and an anti-fake pattern is formed by the sunken portions. The anti-fake patterns can be seen only when a user looks the structure sideways in a beam-focusing manner by a certain angle, and the latent image anti-fake effect is good.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting printing, in particular to a latent image embossing anti-counterfeiting structure and a preparation process thereof. Background technique [0002] In pattern design, changing the angle, thickness, density, shape, etc. of some lines on the base map with regular arrangement of lines can form a hidden image, which is called latent image. Latent image is widely used in pattern anti-counterfeiting design. Latent image patterns are designed on everything from primary anti-counterfeit ordinary tickets to high-level anti-counterfeit banknotes. The latent image not only enhances the beauty of the layout, but also has an anti-counterfeiting effect. There are many styles of latent images, and the anti-counterfeiting function is strong or weak. [0003] The latent image is mainly created by changing the shape and arrangement of the lines. The creation method is different, the appearance charact...
