Embodiment Construction

[0016] An anti-counterfeit seal, which is composed of a single body and a stamp surface. The inside of the stamp surface is the required font, and the outer frame part has anti-counterfeiting lines similar to fingerprints with a line width of ≤0.1mm. Different stamp surfaces can be randomly set by the computer the lines.

[0017] The anti-counterfeit seal is implemented through the following steps:

[0018] (1) Use computer seal typesetting software to draw the seal surface to be made, and use a random algorithm to design anti-counterfeiting lines on the outer frame of the seal surface that are similar to fingerprints and have a line width of ≤0.1mm, and synthesize the seal in the computer image;

[0019] (2) send out the image of the designed seal surface on the photosensitive film by a laser phototypesetting machine, and develop and fix the film to form a film with the image of the seal surface;

[0020] (3) Put the stamp film face down on the photosensitive resin plate, p...

Abstract

This invention discloses false proof seal comprised seal surface with out boarder accompanied with fingerprint-like false proof grain line with width not more than 0.1mm and corresponding preparation method. use computer to software to synthesize seal picture with false proof grain line, form film by laser hologram; take projection and exposure for the film, demould, take rubber hot pressure molding and form seal surface; stick the surface on seal body and finish the preparation. The product has grain line of high precision, hard to copy, increases greatly its false proof property; and the process is convenient, shortcut and safe; it can inhibit effectively criminal act brought by unlawful seal.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and in particular relates to an anti-counterfeiting seal and a method for making the anti-counterfeiting seal. Background technique [0002] With the rapid development of science and technology, the field of seal anti-counterfeiting has also largely integrated high-tech means. In the prior art, from manual cutting out stamps to atomic seals, resin stamps, laser engraved stamps, and the use of fluorescent printing oil in the stamps, adding passwords to the stamps, adding fingerprints and electronic patterns to the five-pointed star, etc., have all improved the seal. Anti-counterfeiting performance. However, the precision of the traditional textured lines is low, and the imitation is relatively easy. Contents of the invention [0003] The invention provides an anti-counterfeiting seal with high-precision netted lines and a seal surface which is difficult to imitate. [0004] The pr...
