Embodiment 1

[0031] Such as figure 1 As shown, the anti-counterfeiting paper according to the embodiment of the present invention includes: a basic paper surface 1, a watermark 3 higher than the basic paper surface 1, and a recessed area 2 lower than the basic paper surface; in this embodiment, the watermark 3 is in the shape of a cloud;

[0032] Such as figure 2 As shown, the watermark 3 is a smooth curved relief area 30 that protrudes from the basic surface of the paper, and the height of the smooth curved relief area 30 changes in a smooth curve along the longitudinal direction of the anti-counterfeiting paper; the smooth curved relief The area 30 includes: a raised portion 301 and a low-lying portion 303 connected to each other; that is, the embossed area 30 of a smooth curved surface is a smooth curved surface with unevenness, and the embossed area 30 of a smooth curved surface has a raised portion 301 and a low-lying portion 303, such as image 3 , the raised portion 301 is higher ...

Embodiment 2

[0054] Such as Figure 5 and Figure 6 As shown, the present invention also provides another embodiment, the main difference between this embodiment and the first embodiment is: the shape of the watermark 3 is different, or the overall shape of the smooth curved surface relief area 30 is different, the first embodiment The overall shape of the smooth surface relief area 30 is a cloud, Figure 5 and Figure 6 The overall shape of the smooth curved surface relief area 30 of the shown embodiment is a flower or a flower head; The area of ​​the degree area is different from the figure of the smooth surface relief area. However, both embodiments have a smooth curved surface relief area 30, and the smooth curved surface relief area 30 has a raised portion 301 and a low-lying portion 303. In the described gradual dew area 91, the safety line covers the low-lying areas of the smooth curved surface relief area. On the part 303 , a part of the safety line located in the low-lying par...

Abstract

The present invention provides anti-counterfeiting paper, which comprises a paper base surface, a watermark higher than the paper base surface, and a concave region lower than the paper base surface, wherein the watermark is the smoothing arc surface embossing zone projecting out from the paper base surface, the smoothing arc surface embossing zone comprises a convex part and a concave part, a safety line is applied in the concave region and passes through the smoothing arc surface embossing zone, the safety line forms a safety line embedding area positioned in the concave region and a line exposing area positioned on the smoothing arc surface embossing zone on the anti-counterfeiting paper, the line exposing area comprises a gradually exposing area and a completely exposing area, the gradually exposing area and the completely exposing area are connected, and in the gradually exposing area, the safety line covers on the concave part of the smoothing arc surface embossing zone, such that one part of the safety line positioned in the concave part exposes to the smoothing arc surface embossing zone, and the other part is covered by a small amount of fibers and is gradually hided in the smoothing arc surface embossing zone. The anti-counterfeiting paper of the present invention has the increased anti-counterfeiting effect.

Description

technical field [0001] The invention relates to the field of paper anti-counterfeiting, in particular to an anti-counterfeiting paper. Background technique [0002] Safety line window opening technology is widely used at home and abroad. At present, the window opening forms are basically divided into two categories. The first type is zebra crossing window opening, which is the most common form of window opening. The zebra stripes are applied on the layout, and a form of window opening is formed by intermittently exposing the paper surface. The second type is the integrated watermark and security line window, this kind of window will set off the layout of the security line as a combined feature of the watermark, and show it to the public at the same time. Through the novelty search, we also saw some other types of window openings, some of which use raised layouts, white watermarks formed by letter graphics as window layouts, realized security line window openings, and compos...
