Embodiment Construction
[0020] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] Such as figure 1 and 2 As shown, an anti-counterfeiting paper with a latent image watermark is formed on the anti-counterfeiting paper 1 with a watermark image and text 2, and the watermark image and text 2 is a latent image watermark image and text, specifically by comparing the thickness of black and white lines It embodies different graphics and texts, and at the same time, the arrangement structure of black and white lines on the anti-counterfeiting paper 1 is composed of black and wh...

The invention discloses anti-counterfeiting paper with latent-image watermarks and a manufacturing technology of the anti-counterfeiting paper with the latent-image watermarks.Watermark image-texts, namely latent-image watermark image-texts are formed on the anti-counterfeiting paper, particularly different image-texts can be embodied through comparison of thick and fine black and white lines, and the black and white lines are arranged on the anti-counterfeiting paper according to a vertical and horizontal arrangement combination of the thick and fine black and white lines so as to form different image-texts.The anti-counterfeiting paper with the latent-image watermarks and the manufacturing technology have the advantages that the anti-counterfeiting paper with the latent-image watermarks is mainly used for paper watermark anti-counterfeit of bank-note paper, securities, passport paper, certificates and the like, latent-image watermark anti-counterfeit is achieved through the paper, in other words, anti-counterfeit is embodied through a latent-image watermark image-text mode, and concealed and manifested watermark image-text change effects are reflected in a watermark image-text viewing process, so that anti-counterfeiting originality of the anti-counterfeiting paper with the latent-image watermarks is embodied through double watermark image-text changes, an anti-counterfeiting technology different from other paper watermark manifestation modes is formed, and importance in first-line mass paper watermark anti-counterfeit is enhanced greatly.
Description
technical field [0001] The invention belongs to the technical field of paper anti-counterfeiting, and in particular relates to a kind of anti-counterfeiting paper with latent image watermark and the production process of the paper. Background technique [0002] At present, white watermark technology is a common anti-counterfeiting watermark technology in banknote paper. In the existing banknote paper, watermark patterns with a relatively simple graphic and text expression are used, resulting in limited anti-counterfeiting ability of paper and easy to be imitated. Contents of the invention [0003] The object of the present invention is to provide an anti-counterfeit paper with latent image watermark and a production process of the paper, which can greatly improve the anti-counterfeit ability of the watermark in view of the above existing problems. [0004] The technical solution of the present invention is realized in the following way: an anti-counterfeit paper with a lat...
