Embodiment 1

[0045] This embodiment provides a wide multi-layer white watermark with the number "100" as the pattern, its manufacturing method and the adopted watermark cage.

[0046] figure 1 Schematic diagram of the wide multi-layer white watermark portion of the watermark cage provided for this embodiment. figure 2 for figure 1 A-A direction view. The watermark cage has a inner net, one side net, two-layer metal mesh and metal sheet, among which, the edge part of the number "100" corresponds to the metal sheet, forming the lines in the pattern, and the central part of the number "100" corresponds to The metal mesh made of two layers of copper forms the surface in the pattern, and the two layers of metal mesh have the same shape, both of which are planar patterns, wherein the width of the line is 0.5mm, the width of the number in the pattern (such as the number 1 width) is about 2mm, and the number height is 7-8mm. Two layers of metal mesh sheets overlap each other, the metal sheets...

Embodiment 2

[0054] This embodiment provides a wide multi-layer white watermark with ancient coins as patterns, its manufacturing method and watermark cage used.

Abstract

The invention relates to anti-counterfeiting paper with a wide multilayer white watermark and a manufacturing method thereof. The invention provides the anti-counterfeiting paper with the wide multilayer white watermark for the first time, wherein the wide multilayer white watermark is a white watermark with different brightness, besides, the pattern of the wide multilayer white watermark is composed of faces and/or lines. The wide multilayer white watermark is composed of a plurality of brightness levels, different parts of the watermark pattern can be equipped with different brightness, and a more distinct contrast can be formed among the different parts of the watermark pattern, so that the wide multilayer white watermark has a stronger anti-counterfeiting feature. Because of the multiple layers, the watermark is better enriched and rich in aesthetic feeling, has a favorable visual effect, is beneficial to identification, and the difficulty in counterfeiting is greatly increased. According to the differences in the watermark patterns, different brightness levels can be selected. The invention further provides a method for manufacturing the anti-counterfeiting paper with the wide multilayer white watermark.

Description

technical field [0001] The invention relates to an anti-counterfeiting paper with watermark and its manufacturing method, in particular to an anti-counterfeiting paper with wide multi-layer white watermark and its manufacturing method. Background technique [0002] In the existing paper anti-counterfeiting technology field, watermark is the most commonly used anti-counterfeiting means, because it is easy to identify and difficult to forge. It has been used for decades, but with the improvement of counterfeiting technology, various watermarks are facing severe tests. At the same time, because counterfeit banknotes are a frequent threat, continuous innovation is required to master the latest anti-counterfeiting technology. [0003] In recent years, anti-counterfeit paper with white watermark (also known as high-gloss watermark) has become more and more popular, and has been used in RMB, Euro and banknotes of many countries. This kind of white watermark is a big improvement co...
