Detailed Description Preferred Embodiments

An identification mark 1 of Fig. la, placed on a paper 2 and intended for paper counterfeit prbtection, is multilayer construction, containing a transparent protective layer 4, under which j there is a region 3 of diffraction relief structure with angular dispersion value corresponded to given light wavelength and given diffraction maximum order.

A reflective layer 5, located under a region 3, is to return a light beam to observer or control device. A glued layer 6, located directly on a paper 2 is to fasten an identification mark 1 is specified point of paper 2.

An identification mark 1 has a region 3 of diffraction relief structure with given angular dispersion value, which occupies the whole area of identification mark (Fig. lb) j i

' A region 3 of diffraction relief structure with given angular dispersion value is oriented in ' definite way on an identification mark 1. In addition, an orientation of region 3 on a identification- mark 1 is completely depended on location of monochromatic light source of control device.

Apart from this region an identification mark 1 can include regions 7 and 7* (Fig. lb) with random positioning of diffraction relief structures, having different angular dispersion value and orientation, which are to disguise a region 3.

I Fig. 2 is a schematic drawing of longitudinal positioning of identification marks 1 on a paper 2 (the paper 2 is not shown on Fig. 2) with periodical changing of the first order diffraction maximum observation angle φ (the first variant of paper implementation),

I . According to the first variant, an angular dispersion of a region 3 of one mark (Di) differ j from' angular dispersion (D2) of a subsequent mark, and angular dispersion (Di) of a subsequent ] mark (D3) differ from angular" dispersion (Di and D2) of previous marks, after that values of angular dispersion are repeated.

The presence of identification marks 1 on a paper 2 with regions (3, 7 and 7*) of diffraction ^' relief structures (for example holograms) allows to visually control the documents authenticity, for example check- or control tapes, at the making stage, during their obtainment by utilizing them organization, at the stage of tape passing through cash register in the case of its preliminary

I" !

personalization, and at the stage of tape storage after its personalization. A check with identification mark 1 is a secure document and comes to customer.

ί The first variant of paper 2 implementation that includes positioning of identification marks 1 in. longitudinal direction with periodic sequence and different angular dispersion of a region 3 (Di, D2, D3) allows to organize a automatic control of check and control tapes from this paper with the help of special control device at any stage for control tapes and up to personalization stage inclusive for check tape.

According to the first variant of paper 2 implementation an authentication control of a paper 2 is realized as follows. An monochromatic light radiation of constant wavelength λ comes to a region 3 at ^ constant incidence angle a. Meanwhile, the first, for example, order diffraction maximum angle ^{1 '} for angular dispersion Di is (pi. '

While a check or control tape moves through control device or cash register, equipped with control device, to the next position, where a region 3 has another angular dispersion value (Di), and, wavelength λ and incidence angle a remains the same, angle of the first order diffraction maximum changes to φζ.

^ Then the process is repeated for a region 3 with angular dispersion (Ds). To each angle of the first order diffraction maximum one can map definite symbol, that makes it possible to code j the tapes. It should be noted that this principle is applicable for rolled material.

Fig. 3 is a schematic drawing of longitudinal positioning of identification marks 1 on a paper 2 (the paper 2 is not shown on Fig. 2) according to the second variant of paper implementation.

According to the second variant, each application mark 1, placed on a paper in longitudinal direction, has a regions 3 with equal angular dispersion values (D). The visual control methods for bqth variants are the same.

But the automatic control performed by control device is realized by another principle.

Since observation angle of the k-th order diffraction maximum including the first one depends on wavelength λ, the angle of the first order diffraction maximum at constant for given j wavelength angular dispersion value (D) of a region 3 for different monochromatic light sources ' wavelengths (λι, Xi, X3), which mark 1, and thus region 3, passes sequentially, changes (φι, q>2, j

At the same time as in the variant to each angle of the first order diffraction maximum one can map definite symbol that makes it possible to code the tapes also.

In both variants of paper 2 implementation with identification marks 1 fabrications and imitations on check or control tape detected by visual and automatic control.

All other protective elements inherent in holograms, such as multidimensional images, hidden image, microtext, guilloche elements, etc., can present on a mark.

i

^! In addition, by using tapes characteristics and their necessary motion during j persorializatibn one can perform automatic instrument control and tapes coding at the expense of a : region 3 of mark 1 with definite angle dispersion value.

Fig. 4 (a, b, c, d) illustrates the making a check and/or control tape method of the present invention. According to the claimed method of check tape, for example, making, identification marks 1 are applied to a paper 2 by any known method, for example by hot stamping method.

J '

After marks 1 application to a paper 2 it is cut along cutting lines 9 (Fig. 4 a, b, c, d) into check and/or control tapes for cash registers or control devices.

The cutting of a paper 2 is done in such a way that identification marks 2 are located either along one edge of check or control tape or along both edges. At the same time size of each edge mark in both cases has to be ½ of identification mark 1.

Obtained by this method check or control tape is passed through cash register or control device for authentication.

! ^■ Fig. 4 (a, b, c, d) shows different ways of made according to Claims 1-2 identification marks 1 position on paper 2, made according to any variants of the present invention, taking into account marks spacing both in longitudinal and transversal direction.

: ¹ A marks spacing in longitudinal and transversal direction of one paper can vary (Fig. 4d) that 'gives the possibility to obtain different product mix of tapes after their cutting that differ by width and coiling length.

A tape of required width is obtained in dependence on specified spacing both in longitudinal and transversal direction.

Moreover, Fig. 4 (a, b, c, d) also illustrates process of a paper 2 cutting along a cutting line 9 into tapes with different location of ½ of identification mark.

₍ Fig 4a illustrates the case when a origin line 8 has zero shift, that is marks in transversal direction are on the same level, but spacing between marks 1 in longitudinal and transversal direction is constant.

] Cutting line 9 of a paper 2 in this case are realized in such a way that check or control tape , '^■ j has identification mark along one edge and size of edge mark is ½ of the identification mark 1. The I paper cutting by two adjacent marks is also possible. That gives a check or control tape with j ; , opposite marks position.

Fig 4b illustrates the case when there is a shift from origin line 8 in transversal direction · ^: through a row that is through a row the origin differs by value equal to half of spacing in longitudinal direction. That results in marks 1 position on a paper 2 as on a chessboard.

In thus case cutting lines 9 passed through marks in such a way that allows to obtain tapes with two-side as on a chessboard position of edge marks on check or control tape remaining size of edge marks equal to ½ of the identification mark 1

j Fig 4c shows position of marks 1 on paper 2 with increasing mark location shift from origin line 8. This variant of marks application is preferable when marks 1 are transferred to paper

2 from transfer material by hot stamping method while paper roll and transfer material roll with .

j j : marks are perpendicular. ! · In this case foil is consumed economically and check and control tapes ^' ' making costs decrease. Cutting of such a paper can be done irrespective of whether edge marks are positioned in one-side or two-side manner.

Fig 4d shows position of marks 1 on paper 2 with different longitudinal (ti, to) and transversal (to, t4) spacing. Here marks shift from origin line 8 is zero, that is marks in transversal direction are positioned on the lame level.

In this case check or control tape is cut from paper 2 along cutting lines 9 into rolls of different width that is conditioned by cash register or control device requirements.

! ¹ , It should be also noted, that during paper cutting process each roll, corresponded by one or , I another parameters of check or control tape, is given a serial number for the purpose of it i identification in the case of authentication, which is applied by special device at the beginning and . the end of a roll obligatory and along a whole roll when necessary.

The identification mark, variants of paper making, been intended for cutting into check and/or control tapes, methods of making of check and/or control tapes from such a material, claimed in the present invention, are simple to make, low-cost, do not require expensive equipment, and are tested in manufacturing environment.
