Description

PRIORITY OF PRINTED BILLS, METHOD AND DEVICE FOR THEIR PRODUCTION

The invention relates to a method for producing a plurality of printed notes, such as forms, billets, lottery or lottery tickets and the like, according to the preamble of claim 1, and to an apparatus for carrying out the method and to a plurality of be¬ printed notes which are produced in accordance with the method according to the invention or by means of a device according to the invention.

The invention will be described below by way of example of a country-specific embodiment of lottery tickets - for Greece. The format for such notes is specified. A reading or writing field occupies a somewhat smaller area of the bill. A substantially free field of the bill, which is used for registration, has a narrow strip which extends across the bill and which serves to identify the bill. The completed ticket is read in and registered at the lottery acceptance point via EDP, the ticket being separated along with this registration along this identification strip, dividing it. With this registration, the read-in number sequence is printed on both sides of the identification strip, on the still free field of the bill. The part of the ticket which has been separated off and is provided with the control registration and has the writing field is then intended - in the event of a win - to serve the lucky owner as identification at the lottery office. There, in order to check and securely identify the winning ticket, the two ticket parts separated in the middle of the identification strip are placed against one another and the conformity of the patterns on the identification strip is checked. In order to keep the possibility of counterfeiting as small as possible, be it by means of copies or reprints, attempts have been made to make the pattern on the identification strip complicated, differently colored. big and to be designed differently for each note, however, has always been restricted due to the printing requirements, so that these patterns are repeated after every 400, but at most 1000, notes. Forgeries cannot be ruled out in this way.

This problem does not only exist for lottery tickets, there are also lottery tickets, tickets for mass and exclusive events, or travel tickets; also for documents, the possession of which also serves as proof of the legality of any claim.

In contrast, the invention has set itself the task of providing a method for producing a plurality of printed bills with identity card character, which can be identified correctly and practically without forgery. This is achieved by the characterizing features of claim 1 -

Advantageous further developments are described by the characterizing features of the dependent claims.

The device for carrying out the method according to the invention is described by the characterizing features of claims 4 to 7, and the notes produced in this way by the characterizing features of claims 8 to 11.

A plurality of such notes are printed in a known manner, preferably in rotary printing presses, the printing form and the printing form support being cylindrical and being driven by gearwheels. The individual notes are printed continuously on paper webs and cut into individual notes after the printing process has been completed. When a printing cylinder is rotated, the printed images are printed for 15 to 20 uses, ie the number of Sehein proofs per revolution. In contrast, the identification images of the control field are rolled in the manner according to the invention printed, the rotational speed of which is changed during the printing process and / or by means of rollers which are not driven, in contrast to the printing cylinders, which are generally driven by gear wheels, for the production of the printed image, as a result of which their print synchronism is ensured. When the paper webs pass through the roller arrangement for producing the identification images, the rollers are therefore preferably moved only by the paper webs which are moved during the entire printing process with an essentially constant throughput speed due to friction.

Because the rollers for the identification images are in particular not driven, rollers of different diameters can be used without any problems, without the need for more complex mechanical equipment for tuning the drive. The various printing dies or embossing or perforation matrices for the identification images can thus be dimensioned independently of the benefits determined by the scope of the printing cylinders that generate the printing images. This means that a single identifier can also drag over a series of notes.

This arrangement, i.e. Different diameters and not completely synchronous and therefore indefinite entrainment of the rollers over the paper webs already results in an increased variability for the printing of the identification images; This is further increased by further measures, such as randomized braking of the rolls, in particular controlled by a random generator, or by cutouts in the rolls.

Another measure can be used for rollers that are driven. For this purpose, their drive is changed continuously or else pulsating, in particular regularly - but preferably randomly irregularly - during the printing process, so that they each have different speed. This can be done using a suitable transformer circuit, in particular controlled by a random generator. A floating bearing of rolls rotating at a constant speed has a similar effect.

Is also due to the large range of variation that can be achieved with the aid of the method according to the invention or by means of the device according to the invention and that due to the different relative positions of the identification images to one another and within the control field for at least 4,000 notes - but preferably for at least 40,000 - Apparently, there is a high level of security against counterfeiting, this is increased by varying the shape and printing medium for the identification images.

This makes it possible to print the individual identification images using different colors. If colors are changed during the printing process - without changing their application rollers, which is possible using known, automatic color changing devices, random color mixtures can occur. Likewise, at least one of the identification images can represent a sequence or a pattern of perforations or embossings.

Characteristic images in the manner of guilloches, i.e. intertwined line grids or ornaments additionally complicate the photomechanical reproducibility of such notes.

The printing of identification images by means of fluorescent and / or magnetic ink increases the possibility of variation and thus the achievable security against counterfeiting, which can be defined by the probability for the presence of two notes with an identical control field.

The checking of the notes, in which the agreement of the identification images on the target dividing line is determined is generally carried out by the human visual apparatus, but other measuring devices can be used, in particular when checking magnetic or fluorescent prints. If, for example, corresponding lines differ by about half a millimeter, this is clearly perceived by the eye. If one therefore presupposes that the control field of a note is 100 mm long, the respective imprint of the at least two identification images is offset by half a millimeter, the possible variation of notes with differing control fields is 200 x 200 given. Each additional measure described above increases this number.

The invention is described below by way of example with reference to drawings. Show it:

1 shows a conventional lottery ticket;

2 shows a lottery ticket from a plurality of tickets according to the invention; Fig.3 and 4 rotary printing presses with different

Printing units for producing a plurality of notes according to the invention;

Fig. 5 and 6 examples of printing units for one-sided or two-sided printing of identification images and Fig. 7, 8 and 9 different rollers for printing identification images.

1 shows an embodiment of a known lottery ticket 1 a, with a printing field 2, in which a printed image 3 is printed, which is identical for all lottery tickets. A largely unprinted registration area 15 has a narrow, strip-shaped control field 4 with two identification images 6.

The hoped for winning numbers are ticked in printed image 3. The lottery ticket 1a is then scanned into the lottery office via EDP, the ticked numbers on both printed out on the side of the control field 4 for control by the owner and for registration by the lottery company. At the same time, the lottery ticket 1 a is cut on a predetermined dividing line 5 running through the control field 4. The part 15a of the note 1a with the printing field 2 with the ticked-on printed image 3 and with the part of the registration area 15 which has the control print remains in the hands of the owner, while the other part of the note 1a with the part 15b of the Registration area 15 goes to the Lotto Society. One each

Part of the control field 4 cut at the nominal dividing line 5 with the two likewise cut identification images 6 is thus on the one hand in the hands of the owner of the lottery ticket 1a or the lottery company.

Should the owner of the lottery ticket be in the fortunate position that his ticked number combination represents a winning combination, then serve

Lottery ticket section as proof of the legal claiming of the prize amount. To do this, not only the

Check imprint on its part 15a of the registration area 15 match the registration imprint on the separated part of the ticket 1a, but the two identification images 6a and 6b must also complement one another when the two lottery ticket sections are placed against one another at the target dividing line 5. If, as in the case of the lottery ticket 1a shown in FIG. 1, each ticket is also given a different number, it has been shown that the possibility of forging the lottery ticket is in this way alone not be ruled out.

The lottery ticket 1 shown in FIG. 2 and representative of a plurality of similar but not the same lottery tickets appears, in itself, to be essentially not different from the lottery ticket 1a described in FIG. Here, too, is a print field 2 with print image 3, a two-part registration field 15 and one that divides it Control field 4 is provided with two identification images 6a1 and 6b1. In contrast to the lottery ticket 1a in FIG. 1, however, the positioning of the two identification images 6a1 and 6b1 - which cannot be represented on the basis of a single lottery ticket - relative to one another and within the control field 4 is not fixed. For this reason, the identification image 6a1 is only partially printed on the lower edge of the control field 4; the supplementary part of the same identification image 6a1 'can be seen on the upper edge of the control field 4. The guilloche-shaped, serpentine second identification image 6b1 also has a different relative position for each of the notes with respect to the first identification image 6a1 and with respect to its position in the control field 4. For some notes, the second identification image 6b1 can also be divided, corresponding to the identification image 6a1 in the in

Fig.2 illustrated printing form. The two identification images 6a1 and 6b1 will preferably be of different colors, wherein a magnetic printing ink can also be used for one of the two identification images 6. A special reading system is used to check the authenticity of the magnetic printing ink, whereby a calibration field must be printed.

It goes without saying that the lottery ticket 1 shown shows only one of many possible variants, in which way and in what form identification images 6 can be arranged in the control field 4. One of the identification images 6, corresponding to the lottery ticket 1a in FIG. 1, can represent a sequence of numbers, the font being guilloche; However, the identification image 6 can also extend over the entire control field 4 if, as will be explained with reference to the method, such an identification image 6 extends over several uses, and only the change in its relative position can be recognized by a sequence of printed, uncut notes on the paper web. An identification image 6 can also be in the form of embossing or

Perforations of any type and shape can be made, and prints in fluorescent color are also possible. Such Identification images 6, which are not visible under normal lighting, can of course also be provided within the registration area 15, and thus outside the visible control field 4. In this case, the entire registration area 15 must be viewed as a control field 4 or can be designed as such, specifically in the form that characteristic images 6 of any type or shape cover it, and registration or control imprints these characteristics 6 take place. Such a ticket is then separated along a nominal dividing line 5, which lies between the parts 15a and 15b of the lottery ticket 1 bearing the two imprints for registration or checking. At which point of a lottery ticket 1 a control field 4 is formed, whether on its front or back, and whether a registration field 15 is to be provided at all for receiving any imprints is, in itself, immaterial. The control field 4 could be located at any point on such a lottery ticket 1, and could even extend across the pressure field 2, which is the same for each lottery ticket 1.

The principle of the invention that only applies to a plurality of tickets, which was only shown on the basis of a single lottery ticket 1, is of interest in the same way for all possible types of tickets that are produced as a plurality, in particular for those who, as already stated in the introduction, are separated for the purpose of registration or control, and for whom - for whatever reason - the necessity should arise that one of the bogus parts is used as identification for the owner or the controlling body for the legal possession or sale. Tickets that have the characteristics described above with the help of the lottery ticket 1 in FIG. 2 are largely forgery-proof and thus represent a perfect legitimation. 3 shows a rotary machine on which a plurality of notes according to the invention are printed. A paper web 16 drawn off from a paper roll 7 is guided through various printing units 11 at a constant throughput speed, the printing cylinders 13 provided for printing the different-colored print images 3 into the printing field 2 being driven in a known manner, in particular via gear wheels, in order to ensure the synchronism of the printing process and thus to produce printing fields 2 with identical and matching print images 3. Inking units 12 with a number of inking rollers are each provided for the coloring during printing. With each revolution of a printing cylinder 13, the same printing field 2 is printed for a certain number of bills, which are called benefits. 3 shows four printing units 11, which could also be arranged one above the other for reasons of space.

This sequence of four printing units 11 is followed by a numbering unit 17, an embossing or perforating unit 19, an identification printing unit 18 and finally a cutting device 20. The numbering unit 17 shown in FIG. 3, like the embossing or perforation printing unit 19, is a conventional unit, i.e. with driven rollers. The rollers can have a larger or a smaller diameter, however, the repetition of the same image, i.e. As shown in FIG. 1, a changing sequence of numbers is always given at the same location with a wandering and thus periodically recurring embossing or perforation image after a certain number of prints.

In contrast, the identification printing unit 18, for example the GP-Tinter (R) (registered trademark of GP-Graphic Equipment Ltd., Stavanger, Norway), the mode of operation of which is described in more detail with reference to FIGS. 5 to 9, does not have any positively driven ones Roll on. With the help of such an identifier Identification unit 6, as described with reference to FIG. 2, are possible in the printing unit 18. In the cutting device 20, the printed paper web 16 is cut into the individual notes.

FIG. 4 shows a variant corresponding to FIG. 3, here two mutually independent identification printing units 18 are provided, which print identification images 6 (FIG. 2) on the front and rear of the notes.

The identification printing units 18 can be positioned in the same way at another point in the printing process, before or after the printing units 11. However, it is advantageous if the printing units 11 responsible for the production of the printed images 3 (FIG. 2) can work as a block, in order to maintain the synchronism required for this purpose.

Both the numbering unit 17 and the embossing or perforating unit 19 are, however, preferably also used as identification printing units 18, i.e. with non-positively driven rollers, to be provided if embossings, perforations or numbering are provided as identification images. In the other case, i.e. As part (s) of printed images 3 in the printing field 2 (FIG. 2), they should have driven cylinders in the same way as the printing units 11.

5 shows the passage of a paper web 16 through an identification printing unit 18a. An inking unit 12 with two — or even more — separate ink containers 21, valve system 22 and pump unit (not shown) make it possible to use the

Applying printing roller 8a to the paper web 16 different colors. For this purpose, the paper web 16 is pressed against the pressure roller 8a via guide rollers 23, whereby it is carried along. This friction-related rotation of the roller 8a is naturally not exactly defined. For example, the

When starting, move the roller more slowly than during the printing process itself; also imponderables like different ones Color assignment, slightly different paper thickness or the contact pressure via the guide roller 23 can influence the rotation speed of the roller 8a.

Embossings can be applied, for example, by means of a second roller 8b, which is also not driven positively.

The undercarriage 12 can be controlled via a remote control unit (not shown), which can be attached to the control panel of the printing press, the - preferably randomized and, in the course of the automation of such printing processes, in particular with the aid of a random generator - the corresponding valves can be controlled for a different ink container 21, so that the printing roller 8a can be wetted with different colors even during the printing process, which results in color mixtures of an unpredictable type and the associated identification image shows color pumps which are difficult to copy.

In FIG. 6, corresponding to FIG. 5, the passage of a paper web 16 through an identification printing unit 18b is shown, in which both the front and the back of the paper web 16 can be provided with identification images. Both rollers 8a are wetted with ink from ink containers 21. Since the paper web 16 is guided in an S shape over the guide rollers 23, its front side and then its rear side are pressed against one of the two rollers 8a. Here, too, at least one of the two rollers 8a can be designed as an embossing or perforation roller or can be connected to a numbering unit.

7 to 9 show examples of rollers 8 for producing identification images 6 (FIG. 2). 7 shows a strip printing roller 8c, in which the rollers 24 carrying the pressure negative for the identification image 6 can be attached to the roller as desired. The outer rollers 24a are moved over the paper web 16 (FIG. 6). FIG. 8 shows a so-called stereotype roller 8d, on which the printing negative 14 is glued, for example as a flexographic printing plate, to the aluminum roller core.

9 shows an anilox roller 8e which has a recess 26 on its surface. This recess, which also extends only over a part of the roller 8e, or can also lie obliquely with respect to the axis of the roller 8e, repeatedly causes an interruption in the entrainment via the paper web and thus an incalculable delay and Shifting the print.

Each of the rollers 8 provided for an identification image, of which FIGS. 7 to 9 show examples, also preferably has a different diameter. The movement of the rollers can also be braked slightly, or these rollers can be lifted off the paper web for a short time via an operating unit, again preferably controlled randomly via a random generator.

It is within the scope of the invention that the rollers 8 are also positively driven, although the differing relative position of the identification images must then be created by means of finely tuned translations. The above-described method according to the invention and the device therefor, on the other hand, impress with simplicity and simultaneous effectiveness.
