A kind of anti-counterfeiting paper and the cage used for making the paper

Abstract

The invention discloses an anti-counterfeiting paper sheet and a net cage for making the paper sheet. The anti-counterfeiting paper sheet comprises a paper sheet and at least one safety line arranged on the paper sheet, wherein the same face of the same safety line on the paper sheet is divided into at least two anti-counterfeiting characteristic representation regions along the length direction; at least one anti-counterfeiting characteristic representation region is a whole-embedded type anti-counterfeiting region, and at least one anti-counterfeiting characteristic representation region is a half-widow-opening type anti-counterfeiting region; the whole-embedded type anti-counterfeiting region and the half-widow-opening type anti-counterfeiting region are alternatively arranged on the same safety line; and the anti-counterfeiting characteristic representation regions on the same face of the safety line are distributed in a longitudinal penetrating manner respectively. With the adoption of the anti-counterfeiting paper sheet, whole-embedded and half-widow-opening anti-counterfeiting characteristics can be realized on the same face of the same safety line so that the anti-counterfeiting function of the paper sheet with the safety line is enhanced; and under the same condition, the quantity of devices for singly opening the paper sheet to put the double safety lines is reduced and the quality risk on the aspect of the safety line is also reduced.

technical field [0001] The invention belongs to the technical field of anti-counterfeit papermaking, in particular to an anti-counterfeit paper and a cage used for making the paper. Background technique [0002] The security thread on the traditional paper usually adopts a separate full-buried type or a half-open window type. In order to further enhance the anti-counterfeiting features of the paper with the security line, there are currently a fully-buried type and a window type that are simultaneously placed on a small open paper.

[0002] The security thread on the traditional paper usually adopts a separate full-buried type or a half-open window type. In order to further enhance the anti-counterfeiting features of the paper with the security line, there are currently a fully-buried type and a window type that are simultaneously placed on a small open paper. Anti-counterfeit paper with a half-open window type security thread, although the anti-counterfeiting ability of this method is enhanced compared with the traditional paper with security thread, but it needs to release two security threads and corresponding two sets of application devices at the same time when copying , and the two anti-counterfeiting methods shown on the paper are realized by two independent security lines, and there is a certain distance between the two security lines. The anti-counterfeiting feature and anti-counterfeiting ability of the security thread are still limited, and it requires double the release device of a single security thread, so that the quality risk of the security thread is large.

In addition, there is also a separate design on the front of the security line that is fully buried or half-opened or fully-opened (full-opened, that is, the security line is not covered by paper fibers and is completely exposed outside), on the back Designed as a fully open window type, this method will reduce the bonding fastness between the security thread and the paper, and the thickness of the paper in the security thread area is thinner than other areas, which will cause quality problems such as paper wrinkling in subsequent printing
