HRP920142A2 - PROCEDURE AND APPARATUS FOR PRINTING MULTIPLE NUMBERS ON LOTTO LEAKERS AND SIMILAR FORMS - Google Patents

Abstract

The invention relates to a method and apparatus for printing multiple numbers on lottery tickets and similar forms. Most printed sheets 1, each of which has a printing box 2 of the same printing form 3 and at least one control box 4 located in the same place for all the slips 1 through which the registration box 15 passes through the dividing line 5 and comprising at least two identification pictures 6, are printed on continuous paper paths 16 and eventually cut. The continuous speed of paper paths 16 remains generally constant throughout the printing process. Identification figures 6a and 6b are printed using rollers 8 of different circumferential speeds, whereby the rotational speed of one of the rollers 8 during the printing process changes and / or at least does not start from the rollers 8.

Description

The technical field to which the invention belongs

The subject of the invention belongs to the field of printing, and especially to the field of printing - printing certain marks on previously prepared matrices. According to the International Patent Classification (IPK), the subject of the invention is classified, i.e. classified and marked with the classification symbol B 41 L 35/00, which defines cylinders for devices or machines for duplicating, copying or printing for office needs or for other business purposes.

Technical problem

The technical problem that is solved by this invention consists in the following: what procedure to use for the production of lotto and most printed tickets with an identification mark, in order to achieve flawless identification and practically impossible forgery? The defined technical problem is solved by the proposed procedure and device for printing several different numbers on lottery tickets and similar forms.

State of the art

An example of the current situation is the lottery ticket used in Greece. The format for such slips is prescribed. The field for reading or writing takes up a little less paper. The rather large free field of the slip used for registration has a narrow strip that runs diagonally across the slip and is used to mark the slip. The completed ticket is loaded and registered at the lotto - receiving office - receiving office via electronic data processing, where the ticket is separated along the marking strip at the same time as it is registered.

During this registration, a loaded series of numbers is printed on both sides of the label strip, on the still free field of the slip. A separate part of the ticket with a control registration and a field for writing will serve as proof to the lucky owner in case of a win with the lottery service. For the purpose of checking and identifying the winning ticket, the separate tickets that are separated in the middle of the tag strip will be placed side by side and the patterns in the tag strip will be checked to match. In order to reduce as much as possible the possibility of forgery, either by means of copying or overprinting, an attempt was made to make the patterns on the label strip complicated, in various colors and differently shaped for each slip, but based on printing-technical procedures this was always limited, so that the patterns are repeated after every 400 at most 1000 slips.

This problem does not exist only with lottery tickets, but also with toto tickets, with tickets for large or exclusive events or with passenger tickets, as well as with documents, the possession of which simultaneously serves as evidence for the exercise of a right.

Most such slips are printed in a known manner in the first row in a rotary printing machine where the printed form and the printing form carrier are cylindrical and are driven via gears. Individual sheets are printed without interruption on paper strips, and after the printing process is finished, they are cut into sheets. When turning the printing cylinder, printed forms are printed for 15 to 20 sheets, i.e. number of ticket prints per revolution.

Description of the solution to the technical problem

The identification images of the control field, on the other hand, are printed in a manner according to the invention, by means of a roller whose rotation speed changes during the printing process and/or by means of rollers that do not move, as opposed to printing cylinders for the production of the printed form, which are usually moved via gears, which ensures synchronized printing. During the passage of paper strips through rollers for the production of identification images, the rollers are moved together with the paper strips at a constant speed during the entire printing process due to friction.

Since ID image rollers are friction-driven, rollers of different diameters can be loaded without problems and expensive technical devices are not required to align the drives. Various printing clichés, i.e. matrices for punching or embossing identification images can thus be dimensioned independently of the use, which is determined by the size of the printing cylinders that produce the printed forms. In this way, one identification image can be extended over a series of slips. Such a lineup, i.e. different roller diameters and fully synchronized cause increased variation in identification image prints, with further measurements as-especially via conditional probability machine controlled-randomized roller deceleration or roller cavities, the variation increases further. Another measure can be applied to rollers that are moving. At the same time, their drive during printing changes continuously and pulsating, regularly or rather randomly irregularly, so that they rotate at different speeds. This can be achieved through a suitable transformer circuit controlled by a conditional probability machine. The same effect also applies to the free placement of rollers that rotate at the same speed, i.e. at a speed that does not change.

If, due to the wide range of variations that can be achieved by the process according to the invention, that is, the device according to the invention, which is determined by the different relative position of the characteristic images to each other and within the control field, at least 4,000 slips - but in the best case for at least 40,000 slips - the data is large security against forgery, and is further increased by variations in the form and printing medium for identification images.

Thus, it is possible to print individual identification images in different colors. If the colors are changed during the printing process - without changing their transfer rollers - which is possible with known automatic color changing devices, accidental color mixtures can occur. Likewise, at least one of the identification images may show a series or pattern of drilling or embossing.

Identification pictures in the form of "guil" holes, i.e. intricate linear rasters, i.e. ornaments, further complicate the photomechanical possibility of reproducing such leaflets. The printing of identification images using fluorescent or magnetic ink increases the possibility of variations and thus the security against forgery that can be achieved and which is defined by the probability of the existence of two slips with an identical control field.

The control of the slips, during which the matching of the identification images on the specified dividing line must be determined, is mostly carried out by ordinary inspection, but devices can also be used, especially in the case of magnetic or fluorescent prints. If, for example, the corresponding lines are defined by about half a millimeter, it is clearly visible to the eye. Let's assume that the control field of one slip is 100 mm long, and each print of at least two identification images is shifted by half a millimeter, thus giving a possible variation on slips with control fields that differ from 200x200. Any further of the above-mentioned measures increases that number. The invention is described in more detail on the example of the method of execution shown on the attached drawing in which:

picture 1 shows an ordinary lotto ticket

Fig. 2 shows a lotto ticket from a plurality of tickets in accordance with the invention

Figures 3 and 4 show a rotary printing machine with different printing mechanisms for producing most of the sheets according to the invention

Figures 5 and 6 are examples of single-sided printing mechanisms

Figures 7, 8 and 9 show different rollers for printing identification images

Figure 1 shows an embodiment of the known lotto ticket 1a, with a printing field 2 on which the printed form 3, which is identical for all lottery tickets, is printed. The registration area 15, which is largely empty, has a narrow control field 4 in the form of a strip with two identified images.

In the printed form 3 with a cross, the numbers for which there is hope to be obtained are indicated. The lottery ticket acceptance service will load the lottery ticket 1a through electronic data processing, the numbers marked with a cross on each side of the control field 4 for control by the owner and registration by the lottery company will be expressed. At the same time, the lotto ticket 1a will be cut on the given dividing line 5 that goes over the control field 4. The part of the ticket 1a with the printing field 2 with the cross marked with the printed shape 3 and with the part of the registration area 15 that has the control printing, remains in the hands of the owner, while the second part of the ticket 1a with part 15b of the registration field 15, which has the registration print, goes to the lottery company. One part each on the given dividing line 5 of the cut control field 4 with both also cut characteristic images 6 is thus in the hands of the owner of the lotto ticket 1a, that is, the lotto company.

If the owner of the lotto ticket is lucky enough that one combination of numbers marked with a cross represents a winning combination, his lotto ticket stub serves as a card for the right to pay out the winning amount. For this, not only the control print on its part 15a of the registration field 15 must coincide with the registration print of the torn-off part of the ticket 1a, but in addition, when placing both pieces of the lotto-ticket from each other, both identification images 6a and 6b must perfectly complement each other on the given dividing line 5. If, in addition, as with the lotto ticket 1a shown in Figure 1, each ticket has a different number, which, as it turned out, does not rule out the possibility of forgery of the lotto ticket.

The representative lotto ticket 1 shown in Figure 2 and for the majority of similar, but not the same lotto tickets, actually does not differ significantly from the lotto ticket 1a described in Figure 1. There is also a printing field 2 with a printing form 3, on two part divided registration field 15 and control field 4 which divides registration field 15 with two identification images 6a1 and 6b1.

Contrary to the lottery ticket 1a of Figure 1, here the positioning of both identification images 6a1 and 6b1, which of course cannot be represented by only one lottery ticket, is relative to each other and is not determined within the control field 4. Therefore, the characteristic image 6a1 on the lower the edge of the control field 4 is only partially printed, and on the upper edge of the control field 4 you can see the complementary part of the same identification image 6a1'. And the second identification picture 6b1, in the form of "guil" holes and showing a winding line, occupies a different relative position for each of the slips in relation to the first identification picture 6a1 and in relation to its position in the control field 4. With some slips, a second identification picture may also 6b1 also be divided, corresponding to the identification figure 6a1 in figure 2 shown in printed form. Both identification pictures 6a1 and 6b1 are in different colors, and magnetic printing ink can also be used for one of the two identification pictures 6. To test the authenticity of the magnetic printing ink, a special loading system is used, in which case the field must be printed calibration.

It is self-explanatory that the presented lotto ticket shows only one of many possible variants, in which way and in which form the identification pictures 6 can be placed in the specific field 4. One of the identification pictures 6 can correspond to the lotto ticket 1a of Figure 1, display a series of numbers, whereby the letter can be in the form of "guil" holes; however, the identification image 6 can also extend over the entire control field 4, if such an identification image 6 is taken for multiple uses, and the change in its relative position can only be discerned on a series of printed, still uncut slips on the paper tape, which will still be shown in the procedure. The identification picture 6 can be made in the form of embossing or sanding of any type and shape, and prints in fluorescent color are also possible. Such identification images 6, which cannot be seen under normal lighting, can of course also be provided inside the registration field 15, and thus outside the visible control field 4. In this case, the entire registration field 15 must be considered a control field 4 or it can be shaped as such and in the form that it is covered by identification pictures 6 of each type or form, and registration or control prints are made on these identification pictures. The separation of such a ticket is done along the given dividing line 5, which is located between parts 15a and 15b of the lotto-ticket 1, which have both prints for registration, i.e. control. In which place of the lotto ticket 1 will be the control field 4, whether on its front side or on the back side and whether the registration field 15 for putting any prints must be provided, is not important in itself. The control field 4 could be located anywhere on one such lotto ticket 1, it could even extend diagonally across the printing field 2 which is actually the same for each lotto ticket 1.

The principle of the invention, which comes to the fore only with the majority of tickets, and which, admittedly, is shown with the help of a single lotto ticket 1, is interesting in the same way for all possible types of tickets, which are produced as the majority, especially for those, which, as which has been established in the introduction, they are torn or divided for the purpose of registration or control and where, for any reason, there is a need for one part of the slip to serve as a certificate of valid possession or sale to the owner or control service. The tickets that have the characteristics described in the example of the lotto ticket 1 of Figure 2 are largely safe against forgery and thus represent flawless identification.

Figure 3 shows the rotary machine, on which most of the slips are printed in accordance with the invention. The paper strip 16 printed from the paper roll 7 is guided at a constant continuous speed through various printing mechanisms 11, whereby the printing cylinders 13 provided for printing the printing forms 3 in the printing field 2 are driven in a known manner via gears, in order to ensure synchronism of the printing process and thereby to produce the printing fields 2 with identical and corresponding printing forms 3. The ink application devices 12 with many ink rollers are provided for providing ink during printing. At each revolution of one printing cylinder 13, for a certain number of slips, which are marked for use, the same printing field 2 will be printed.

Figure 3 shows four printing mechanisms 11, which due to lack of space can be placed one above the other.

A numbering mechanism 17, an embossing or punching mechanism 19, a marking printing mechanism 18 and finally a cutting device 20 are connected to this series of four printing mechanisms 11. Figure 3 shows the numbering mechanism 17 shaped the same as the embossing mechanism. that is, drilling 19, as a conventional mechanism, i.e. with moving rollers. At the same time, the rollers can have a larger or smaller diameter, which nevertheless gives the repetition of the same image, i.e. as shown in Figure 1 - a series of numbers that always changes in the same place with a moving and thus periodically returning imprinted or punched shape after a certain number prints.

In contrast, the identification image printing mechanism 18, eg, GP-tinter (R) (trademark of GP-Graphic Equipment Ltd., Stavanger, Norway), the mode of operation of which will be shown in Figures 5 to 9, does not have positively driven rollers. With the help of such a mechanism for printing the identification image 18, the identification images 6 are made possible, as described with reference to Figure 2. In the cutting device 20, the printed paper strip 16 is cut into individual sheets.

Figure 4 shows a variant corresponding to Figure 3, whereby two mechanisms for printing the identification image 18 independent of each other are provided here, which print the identification images 6 (Figure 2) on the back of the slip.

The mechanism for printing identification images 18 can be positioned in the same way in another printing place, in front of or behind the printing mechanism 11. However, it is still advantageous if the printing mechanism 11 used for the production of printing forms 3 (Fig. 2 ) can work as a flawless maintenance block for that necessary synchronism.

The numbering mechanism 17, as well as the embossing or punching mechanism 19, must also be provided as mechanisms for printing the identification image 18, i.e. with rollers that are not forcibly driven, if embossing, punching, or numbering as identification images will be provided.

In the second case, i.e. as an integral part (parts) of the printing forms 3 in the printing field 2 (Figure 2), they must have driven cylinders in the same way as the printing mechanisms 11.

Figure 5 shows the passage of the paper strip 16 through the mechanism for printing identification images 18a. The ink application device 12 with two or more separate ink tanks 21, a valve system 22 and a pump unit (not shown) means that the paper strip 16 is pressed onto the print roller 8a via the guide rollers 23, which also he grasps. This rotation of the roller 8a caused by friction is not precisely defined. Thus, for example, the roller 8a will move more slowly when starting than during the actual printing process; Imponderables such as different ink application, bit, paper thickness that differs or the pressing force over the guide rollers 23 can also affect the rotation speed of the roller 8a.

By means of the second roller 8b, which is also not forcibly driven, embossing can be achieved, for example.

Via a remote control unit (not shown), which can be mounted on the control table, the ink application device 12 can be controlled, whereby the valves on the the second printing roller 8a which can be wetted with different colors, whereby color mixtures are obtained which are not predetermined, and the identification images 6 have color shades which are difficult to copy.

Figure 6 shows - corresponding to Figure 5 - the passage of the paper strip 16 through the mechanism for printing the identification picture 18b, in which the identification pictures 6 can be applied both on the front side and on the back of the paper strip 16. Both rollers 8a are wetted with ink from the ink tank color 21. Since the paper strip 16 in the shape of the letter S is guided over the conducting rollers 23 on both rollers 8a, its front side is pressed first, and then its back side. Here, too, at least one of the two rollers 8a can be designed as an embossing or punching roller, that is, it can be connected to a numbering mechanism.

Figures 7 to 9 show examples for rollers 8 for producing identification images 6 (Figure 2). Figure 7 shows a roller for printing tapes 8c, where rollers 24 can be placed on the roller if desired, which have a negative for the identification image 6. The outer rollers 24a move over the paper strip 16 (Figure 6).

Figure 8 shows the so-called stereotyped roller 8d, on which negative 14, for example, as a cliché of flexographic printing, is pasted on the aluminum core of the roller.

Figure 9 shows the raster roller 8e, which has a groove 26 on its surface. This groove, which extends only through one part of the roller 8e, i.e. it can lie diagonally on the axis of the roller 8e, always causes a break when it is taken over the paper strip 16, and thus retention and displacement prints.

Each of the rollers 8 provided for each identification image 6, examples of which are shown in images 7 to 9, has a different diameter. Via the control unit - which is again randomized via the conditional probability machine - the movement of the roller 8 can be slightly braked, that is, the rollers 8 can be briefly removed from the paper strip 16.

In the framework of the invention, the rollers 8 are also forcibly driven, whereby the differing relative position of the identification images 6 must be performed using finely adjusted calculated transmission ratios. The above-described method according to the invention, i.e. the device for that method, stand out for its simplicity and simultaneous effectiveness.
