Abstract

The present invention relates to a colour fibre for making antifalse paper and its production method. It is a single polychromatic section fibre formed from at least two monochromatic section fibres which have clear visual difference. According to that when the monochromatic sections with different colours are printed on the single fiber, the butt-jointed place between monochromatic sections has no disalignment, but the but-jointed place between colour fine lines printed by printing method adsolutely has disalignment, said invention utilizes this difference, and when this colour fibre is added into the paper in the course of making paper, its visual effect features can not be imitated in the printing process.

Description

Single multi-color section fibre and manufacture method thereof

The present invention relates to a kind of colored fiber and manufacture method thereof that cheque paper is used of making, specifically, relate to that a kind of it has the fiber of its visual effect characteristic of the more difficult imitation of printing when it adds in paper, its architectural feature is: be made up of two sections monochromatic section fibres with obvious vision difference at least on the single fiber.

Colored fiber added in the paper make the history in existing more than 100 year of cheque paper, at the beginning of 1880, seal paper money factory of Prussia country has bought the seal paper money paper patent right with inventor James Wilcocks naming; This paper is exactly to have added coloured string in paper pulp, and this is the blank of modern anti-false fiber paper.The Ji Saikede failure Ang Te company of Leipzig, Germany in 1906 adds the paper slip that the paper of printed different colours is cut into same length in the l Water Paper paper web, makes false proof dedicated paper and has applied for patent.Nineteen thirty-nine improves to some extent again, and printed sequin is added paper pulp, produces bank-note paper, has also applied for patent.As the dollar that the U.S. printed nineteen twenty-eight in the past, red blue two color fibres only are distributed in the long and narrow zone of nominal value center.

In paper-making process, add colored fiber why anti-fake effect is arranged, be because utilized the personator can only be usually buy paper ready-made on the market and be difficult to own have the ability and courage have high input greatly expose papermaking, particularly make high-grade paper and carry out illegal counterfeit characteristics, reach false proof purpose.All adopted the anti-counterfeiting technology that in paper-making process, adds colored fibre with paper as the seal paper money paper of usefulness such as existing 100 dollar bills, 100 yuan, 20 yuans of new editions, 1000 yuan of Hongkong dollars of new edition, Swiss franc, Dutch guilder, Indonesia's coin, Austrian Schilling and a large amount of marketable securities, more particularly, also having added in the used art post paperboard of the famous hard box of all cigarettes of Hongta Group (as brands such as Hongta, A Shima, Yuxi) of China at present is the red fiber of purpose with false proof, but colored fiber described above is single monochromatic fiber.This monochromatic fiber except that itself manufacture difficulty not quite, its fatal shortcoming is: from monochromatic fiber visual effect, the personator is very easy to imitate to the life out with printing technology, promptly uses 5 times of magnifying glasses to observe and also is difficult to identify the fiber or the multi-color cord of printing.Run into when being bank note, whether common user cannot carry out destructiveness identification with the method for tearing paper, be true fiber and be difficult to discern it with vision.The fact proves effectively that also the colored fiber in present nearly all counterfeit money all is the imitated of printing multi-color cord, and this makes the papermaking anti-counterfeiting technology of its this kind adding colored fiber be difficult to bring into play its real effect.

The objective of the invention is to, overcome the shortcoming that the existing visual effect that adds the single monochromatic fiber in the cheque paper easily is printed technology imitation true to nature, provide a kind of being difficult to be used for the false proof single multi-color section fibre of papermaking with what printing technology was imitated.

To achieve these goals, the present invention is according to the monochromatic section of printing and dyeing different colours on single fiber, the docking point place does not have a bit dislocation between its monochromatic section fibre, and be docked at the absolute being dislocation of contact place with printing process printing color fine rule, utilize the existence of this difference, when this colored fiber is added in the paper in paper-making process, there is printing to be difficult to the characteristic of its vision of imitation.

Support that realistic basis of the present invention is the objective limitation of printing chromatography precision, in existing flat stamping, protruding seal, silk-screen, four kinds of mode of printings of gravure, flat stamping (also claiming offset printing) is that chromatography precision is the highest, overprint error is made up of two parts, the one, the overprint error of printing equipment itself, be generally 0.1mm, the 2nd, paper is met water (offset printing process needs the water damping) and the stretching, extension that produces and the overprint error that causes in the offset printing process, stretch amplitude is relevant with the character and the quality of paper, and these two kinds of errors are irresistible objective reality.Some is very big with the above two parts overprint error of occasion of thin paper printing, can't go to finish chromaticity printing with printing process in other words conj.or perhaps at all, and for example we use 17g/m ²-25g/m ²The thin paper of grammes per square metre removes to print specification in tax invoice or the Medicine box and other uses the occasion of thin paper, at present, all in the world offset presses all can't be finished the defeated paper of this thin paper, say nothing of and finish accurate chromatography, even the printing of offset printing function, the chance water distortion of this thin paper is also very big.At present, this thin paper can only adopt the protruding India side formula of hand feeding, and this protruding India side formula not only lines are thick, can not finish accurate chromatography especially.

Fig. 1 (a), Fig. 1 (b) have shown the dislocation effect when going to imitate a kind of diameter when the offset printing overprint error that causes when above-mentioned two kinds of combined factors is for 0.1mm is the single double-colored section fibre of 0.04mm (diameter that is equal to fiber on the RMB) intuitively: 1 (a) is the visual effect figure of single double-colored section fibre, 1 is the docking point of red color segment fiber 2 and green segment fiber 3 among Fig. 1 (a), no matter perusal is still observed with the magnifying glass of any multiple, does not all have a bit dislocation; Fig. 1 (b) is red fine rule 4 and the green fine rule 5 with ink printing, because the limitation of chromatography precision, it is certain to occur dislocation on docking point 6, when (in case of necessity also can by the magnifying glass about 10 times) finds this dislocation when with the naked eye, then can be certainly print counterfeit.

After having adopted the single multi-color section fibre that has according to the present invention, can easily identify the counterfeit paper that utilizes printing technology to make, so have stronger antifalsification and easy identity.

That Fig. 2 represents is first embodiment of single multi-color section fibre of the present invention;

That Fig. 3 represents is second embodiment of single multi-color section fibre of the present invention.

Fig. 2 has represented the single double-colored section fibre that is added in making the process of cheque paper, this kind colored fiber is made up of two monochromatic section fibres of each its color of tool, is made up of red color segment fiber 1 and green segment fiber 2 as this colored fiber in this embodiment.

Fig. 3 has represented the single three look section fibres that are added in making the cheque paper process, this kind colored fiber is made up of three monochromatic section fibres of each its color of tool, is made up of green segment fiber 1, red color segment fiber 2 and Lan Se section fibre 3 as this colored fiber in this embodiment.

Obviously, all can be differentiated significantly owing to there is tangible vision difference between the monochromatic section fibre of each of above-mentioned two kinds of single multi-color section fibres by naked eyes.Yet, even someone attempts to palm off with printing technology, print out slightly to be seen as and have two monochromatic fiber patterns with the colouring section, but as long as error is arranged slightly during every polychrome section chromatography, joint just can produce dislocation, just be easy to be discovered out by ordinary person, if further observe with the magnifying glass of 5 times or higher multiple, the printing butt joint dislocation between the adjacent look section is just more very clear, makes its forgery appearance abundantly clear.

Therefore, adopted, overcome the existing deficiency that contains single monochromatic anti-false fiber paper, thereby made this kind cheque paper have stronger anti-counterfeiting performance and be ordinary person's easy identity according to behind the single multi-color section fibre of the present invention.

Another aspect of the present invention provides a kind of manufacture method of making this single multi-color section fibre, this manufacture method is based on the thermal dye sublimation transfer printing principle, it will have the dyestuff of heat sublimation character in advance and make printing ink, with method of printing it is imprinted on the hot transfer printing carrier material, this carrier material is paper normally, it also can be resistant to elevated temperatures organic film (as mylar) etc., the pattern of printing is made up of the colour bar of certain width different colours, colour bar accurately links to each other side by side, the colour bar width is corresponding with each monochromatic section fibre length of the fiber that will make, utilize hot transfer apparatus, with the colour bar pattern sublimation transfer on the transprint material to arranging on the good fiber through unclogging and readjusting, the colour bar direction of pattern is vertical with the orientation of fiber, through certain temperature and time, the heat sublimation dyestuff can deep and thoroughly arrive the surperficial and inner of fiber, and cut staple is then made single multi-color section fibre at regular intervals; The great advantage that adopts printing transferring method is that printing can guarantee very good precision.

Below we describe this manufacture method in detail with a specific embodiment: for example to make a kind of single multi-color section fibre, fiber is made up of blue, red, green three look sections, long 6mm, diameter 0.03mm, every look segment length is 2mm, because paper-making process must be through 180 ℃ high temperature, so select resistant to elevated temperatures recessed human relations fiber.

Fig. 4 (a), Fig. 4 (b) have represented the manufacture process of above-mentioned fiber, at first make gravure by the dimensions of Fig. 4 (a), and the width of blue colour band 1 is 4mm among Fig. 4 (a), and the width of red zone 2 is 2mm, and green is 4mm with 3 width; 4 position selects the DISPERSE DYES of corresponding form and aspect to make printing ink corresponding to the cutting the position and make gravure by this specification pattern of fiber among Fig. 4 (a), adopts gravure equipment to be printed to the continuous web-like hot stamping paper of wide 40cm fabric width.

Fig. 4 (b) has represented to utilize the process of thermal dye sublimation transfer printing paper printing and dyeing polychrome fiber: 1 is the web-like thermal dye sublimation transfer printing paper that is printed by intaglio printing press among the figure, pattern transferring is in the bottom surface of transfer paper 2, fiber is unclogged and readjusted equipment 3 mode thigh fibre finish is become side by side neatly and closely fiber alignment 4, enter drum-type heat transfer machine 7 then together, heater 8 is heated to about 200 ℃ cylinder 7, cylinder 7 rotates by 2 rev/mins speed, cylinder is heated transfer paper, DISPERSE DYES distillation back direct dyeing on it is on fiber, the 5th, the pressure woollen blanket, its effect is that transfer paper is contacted with fibre compact, 6 is the cleaning plant of woollen blanket, 9 transfer papers for transfer printing, 10 is the continuous fibers of shades of colour dyestuff in the transfection, 11 is cutting device, its effect is to cut fiber accurately, dividing the position of cut staple is 4 positions among Fig. 4 (a), and the fiber that cuts like this is red color segment middle blue, green segment is at the single three look section fibres at two ends, and 12 for cutting the gathering-device of fiber.
