A kind of manufacture method that adopts the cheque paper of anti-false fiber is characterized in that adding claim 1 described single fiber in paper-making process in paper pulp, and the cross section of described single fiber is pancake or rectangle.

Anti-false fiber of the present invention is made of single fiber, every fiber comprises two corresponding up and down surfaces, the color characteristic of upper surface is different with the color characteristic of lower surface, and this difference makes people's naked eyes can tell the difference of upper and lower surface color characteristic easily.When this anti-false fiber is added in paper-making process make cheque paper in the paper pulp after, the color characteristic of the upper surface of the anti-false fiber in the cheque paper is presented in the upper surface of cheque paper, the color characteristic of lower surface is presented in the lower surface of cheque paper, and owing to be same fiber, its upper and lower surface overlaps fully, so when meeting the light observation, the color segment of upper surface and the color segment of lower surface are overlapping fully, do not have a bit dislocation.If the counterfeiter attempts to remove to imitate the color character that the anti-false fiber in the cheque paper of the present invention presents at positive and negative with mode of printing, it must stamp the color characteristic on two surfaces of anti-false fiber at the tow sides of paper respectively, in the time of also must guaranteeing to meet the light observation simultaneously, pattern at the different two-face printings of paper is overlapping fully, a bit dislocation can not be arranged, and this be just existing printing technology itself intrinsic defective, the pattern that is the printing technology different two-face printings that can not reach paper is overlapping fully, and a bit dislocation can not be arranged.So the present invention has overcome the single monochromatic anti-false fiber paper of existing adding and easily has been printed the counterfeit defective of mode, provides printing technology to be difficult to counterfeit anti-counterfeiting technology.The present invention also has and is easy to the true and false advantage of non-destructive Direct Recognition, promptly just but direct convenience identification is true and false by people's naked eyes, identification step is simple, identifying is as follows: a, the vitta of an optional like fibrous is observed in paper, whether this root vitta of contrast has different color characteristics at the tow sides of paper earlier, if the tow sides color characteristic is identical, then can directly be judged to counterfeit; B, if this root vitta in the tow sides color characteristic difference of paper, then carries out next step judgement, promptly meet light and observe this vitta, see whether the pros and cons of vitta overlapping fully, if not overlapping, promptly have dislocation, then decidable is counterfeit.

So the invention provides a kind of mode of printing technology counterfeit, that non-destruction identification is faked that prevents, this does not allow to adopt the occasion such as tearing destructive recognition methods such as observation significant for bank note, marketable securities etc.

Further specify the inventive features of manufacture method that the present invention adopts the cheque paper of anti-false fiber at this, promptly how to realize making the upper and lower surface of the anti-false fiber that adds in the paper after forming cheque paper, can guarantee to be apparent in respectively the positive and negative surface of cheque paper.After the cross section of anti-false fiber is made into pancake or rectangle in advance and adds paper pulp, in the subsequent process of papermaking whitewashing and paper formation, the inevitable minimum state of energy state that is in all the time of the fiber of this cross sectional shape, after making paper, the inevitable positive and negative with paper of the upper and lower surface of the anti-false fiber in this cross section is approximate parallel or parallel, has so just guaranteed that the upper and lower surface of anti-false fiber is apparent in the positive and negative surface of cheque paper respectively after forming cheque paper.

Anti-false fiber of the present invention just is not applied to can also be applied to make between the plastics false proof plastic products in the papery anti-fake material.
