Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the drawings.
[0021] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0022] Such as figure 1 with 2 As shown, an anti-counterfeiting paper with a latent image watermark, a watermark graphic 2 is formed on the anti-counterfeiting paper 1, and the watermark graphic 2 is a latent image watermark graphic, specifically a black and white line thickness comparison Reflecting different graphics and texts, while the arrangement structure of black and white lines on the anti-counterfeiting paper 1 is arranged vertically and horizontally with black and white line thicknesses...

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 particularly relates to an anti-counterfeiting paper with a latent image watermark and a manufacturing process of the paper. Background technique [0002] At present, the white watermarking technology is a common anti-counterfeiting watermarking technology in banknote paper. In the existing banknote paper, watermark patterns with a relatively single graphic and text expression are used, resulting in limited anti-counterfeiting ability of the paper and easy to be counterfeited. Summary of the invention [0003] The purpose of the present invention is to provide an anti-counterfeiting paper with a latent image watermark that can greatly improve the anti-counterfeiting ability of the watermark, and a manufacturing process of the paper. [0004] The technical scheme of the present invention is realized as follows: an anti-counterfeiting paper with a latent image watermark, on which a wa...
