Abstract
Security of game cards such as instant lottery tickets can be improved by locating a confusion pattern below a primer layer on the game cards substrate and by locating another confusion pattern on a release coat above the game card play indica. Game card security can be further enhanced by using confusion pattern ink that bleeds through the game card in response to the application of various solvents.
Description
2~9~rl2~3 GAME TICKEI' CONFUSION PATTERNS
FIELD OF THE INVENTION
The invention relates to the field of game tickets and in particular to security features in instant type game or lottery tickets.
BACKGROUND OF THE INVENTION
Game cards such as lottery tickets and promotional game cards typically contain hidden play indicia such as numbers, symbols or messages that indicate whether or not the 10 card is a winner or has a certain value to the player. The play indicia is normally covered by a opaque coating material for ex~mple a latex compound which can be scratched off by the player to reveal the play indicia after the ticket has been purchased or otherwise obtained by the player. Examples 15 of various game card and instant lottery ticket construction are disclosed in U.S. Patents: 4,174,857, 4,273,362, 4,299,637, 4,725,079 and 4,726,608.
Of paramount importance to the game card industry and in particular the instant lottery industry ls security.
20 One method of breaching the security of game tickets is by candling. Here a bright light is applied to the game card in an effort to read the play indicia either though the latex covering or the back of the ticket. A number of techniques have been developed to counter candling including the use of 25 a foil layer such as aluminum foil as part of the game ticket. This foil layer blocks visible light and therefore . . . . .
. . , :
~' ; ' ' ' :
:
,~ .
~9~ 7~3 makes it virtually impossible to read the play indicia through the opaque coating. However the use of a foil layer has a number of significant di.sadvantages including the Pxpense of an extra process step t:o add the foil layer to the card or ticket as well as the cost of the ~oil itself. Also with the increased emphasis on recycling, aluminum foil can present problems and costs to game card manufacturers along with the users of game cards such as state lottery administrations. For example used lottery tickets must be collected from the public and then the foil has to be separated from the rest of the ticket before it can be recycled.
A second approach to prevent candling is to imprint confusion patterns on the ticket. A confusion pattern obscures or otherwise confuses the image of the play indicia when visible light is shined though the game card thus making it difficult or impossible to read the indicia before the latex covering is removed. In one example illustrated in U.S. Patent No. 3,900,219 a confusion pattern is printed on the back of a lottery ticket. Although confusion patterns printed on the back of the ticket help to prevent candling, other methods exist for compromising the security of the ticket. For example, delamination can be - used to overcome the security provided by confusion patterns printed on the back o~ the ticket. The back ticket layer containing the confusion layer is separated or delaminated from the ticket. Once delaminated, the indicia can be read by candling. Confusion patterns consisting of irregular opaque areas have also been printed on the top surface of the card stock below the opaque mask. Another technique is described in U.S. Patents Nos. 4,095,824 and 4,241,824. In this case, to prevent photocopying though the opaque mask, a confusion pattern is printed over the play indicia using a transparent media or a media having a color differing from the color of the play indicia so that the confusion pattern -.~ ' ' ~ . . .
:
2 0~ 72 ~3 will not obscure the play indicia when the opaque mask is removed by a player. Another confusion pattern is then printed below the play indicia on the card material immediately below the play indicia. One disadvantage of this approach is that unless the upper confusion pattern is completely transparent it existence will be apparent to those individuals who may be considerinc1methods ~or breaching game card security. In addition the upper confusion pattern as described makes very little contribution to the prevention of candling.
Wicking is another technique that has been used to read the pla~ indicia without having to remove the opaque mask. In wicking a solvent containing alcohols, ketones, acetate, esters, alaphtic or amine solutions is applied to either the back or the front of the game card resulting in the bleed through of an image of the play indicia. This makes it possible to determine if a game card is a winner before the opaque coating is removed. One approach to prevent wicking is to place solvent responsive dyes in the opaque coating as described in U.S. Patent 4,726,608. This is a relatively expensive process however. Confusion patterns, as described above, have not generally been effective in countering wicking.
SIJMMARY OF THE lNV~:N'l'lON
It is, therefore, an object of the invention to reduce the cost and to enhance the security of game cards by the use of particular locations and characteristics of confusion patterns.
It is another object of the invention to provide a game ticket which is secure against delamination.
It is a further object of the invention to provide a secure game ticket which does not have substantially all of its back surface covered with a confusion pattern and 2~3~ 7~S~
therefor has substantially all of its back surface available for display purposes.
It is another object of the invention to provide a game card having a removable opaque coating covering a set of play indicia with a confusio~ pattern located above the play indicia such that the confusion pattern is also removed when the opaque coating is removed by a player.
It is also an object of the invention to provide a game card havin~ a removable opaque coating covering a set of play indicia with a confusion pattern that bleeds in the presence of a solvent that also causes the hidden play indicia to bleed.
It is an additional object of the invention to provide a game card having a removable opaque coating covering a set of play indicia and a confusion pattern which is removed with the removable opaque layer.
It is a further object invention to provide a game card having a card substrate where a confusion pattern is printed with an ink, that bleeds in the presence of one or more solvents where the same solvents also cause bleeding of the hidden play indicia, on the upper surface of the substrate and below a set of play indicia which in turn is covered by a removable opaque coating. Security can be further enhanced by providing a second confusion pattern printed on a release coat that covers the play indicia.

''~ ' ' , 2 ~ 3 DETAILED DESCRIPTION OF THE INVENTION
Fig. 1 shows in exploded form a representative ; example of the construction of a game card 10 which illustrates a pref~rred embodimlent of the invention. For clarity only a portion of the various internal layers of the card 10 are shown in Fig. 1. The first layer of the card 10 is a substrate 12 preferably composed of paper. A primer layer 14 is applied to the substrate 12 and then a blue along with a red banday pattern 16 and 18 are printed on the substrate primer 14. The purpose of the bandy patterns 16 and 18 is to detect vertical ticket splitting. On top of the banday patterns 16 and 18 a set of play indicia 20 is printed which in the example of Fig. 1 include a bell, a cherry and a plum. To protect the play indicia 20 a seal coat 22 is applied over the play indicia 20 and then a release coat 24 is applied on top of the seal coat 22. In order to prevent visual observation of the play indicia 20 a removable opaque mask or coating 26, usually composed of a latex compound, is applied to the release coating 24. A overprint layer 28 which can include game information such as a set of game play indicators 30A-D forms the top most layer of the game ticket 10. A more detailed description of the basic components o~
the game ticket 10 is provided in U.S. Patent No. 4,726,608.
In the embodiment of the invention shown in Fig. 1, candling can be inhibited by a permanent confusion pattern 32 printed on the substrate 12 underneath the primer coating ; 14 and a removable confusion pattern 34 printed on the top of the release coat 24 beneath the removable coating 26. By locating the permanent confusion pattern below the primer layer 14 visual interference with the play indicia 20 is avoided and the existence of this confusion pattern 32 is not readily apparent to the public. In some instances it may be desirable to print an uniform opaque coating such as gray or black ink or a color matching the play indicia 20 below the primer layer 14 instead as the confusion pattern 32. The : . .
2 ~
removable confusion pattern 34 can be a uniform opaque coating as well and can be print:ed in black or gray ink or in a color matching the play indicia 20. Since the removable confusion pattern 34 is located b~tween the removable coating 26 and the release coat 24 it wil:L be removed when the opaque mask 24 is scratched off by a p].ayer. Thus this confusion pattern 34 will likewise not intl3rfere with the observation of the play indicia 20 when the mask 26 has been removed by the player nor will its existence be apparent to the public.
To further enhance the security of the game card 10, one or both of the confusion patterns 32 and 34 can be printed with an ink that include visible materials that go into solution or dispersion when they come in contact with various solvents such as alcohols, ketones, acetate, esters, alaphtics or amine solutions that are typically used in wicking. In this manner breaching the security of the game card 10 by wicking can be prevented because the confusion patterns 32 and 34 will tend to bleed through the ticket with the play indicia 20 making the play indicia 20 indiscernible.
Another advantage of using a solvent responsive ink in the removable confusion pattern 34 is that in some cases it eliminates the need to use dyes in the removable mask 26 to prevent wicking. This object can be achieved by incorporating solvent responsive dyes into the confusion pattern ink.
Preferably the confusion pattern inks 32 and 34 should have the same bleed characteristics as the play indicia ink 20 in order to inhibit wicking. For example, if the play indicia 20 is not subject to bleeding then the confusion pattern inks should not be subject to bleeding.
A suitable confusion pattern ink for use with play indicia 20 that have the color black would include a gray or black grind base. Ink having a 16% gray or black ink grind base by weight component along with 16% by weight methyl ~ 7 .~J3 ethyl ketone; 6~ by weight K-1717B resins; 10~ by weight pentalyn 255 resin; 8% by weight DM-55 acrylic resin and 16W6 N/C white base components will bleed on contact with solvents containing ammonia or other amines as well a5 alcohols.
Dependin~ upon the type and color of ink used for the play indicia 20, other types of dyes that will form a solution or dispersions with the solvents can be used for the con~usion pattern ink including inks of difeerent colors than black or gray. It is also desirable that the solvent responsive dye match the color of the play indicia ink. The density of the dye should match the density of the play indicia ink as well otherwise it may be possible to read the play indicia 20 through the confusion patterns 32 and 34.
The preferred form of the confusion patterns 32 and 34 is a random series of portions of the symbols used in the play indicia 20 having the same line weight. An example of such a confusion pattern is provided in Fig. 2. The confusion pattern 32 should also have the same general printing characteristics as the play indicia 20, to increase the apparent similarity between the confusion pattern 32 and the play indicia 20. For example, if the play indicia 20 are printed as groupings of small dots, as is the result with ink jet printers, the confusion pattern 32 should also be printed as groupings of small dots. It may also be desirable to vary the print characteristics of the play indicia 20 and the confusion pattern 32. For example, it may be desirable to print the individual symbols in the play indicia 20 with different print densities and line weights. The individual symbols or portions of the confusion pattern 32 would then also be printed using varied characteristics. Printing the confusion pattern 32 and the play indicia 20 with varying characteristics helps to overcome difficulties in matching the specific characteristics, such as print density, o~ the play indicia 20 and the confusion pattern 32 and thus increases the apparent similarity between the play indicia .
, :
2 i~ J .3 20 and the confusion pattern 32. However/ as indicated above, a uniform coating of, for example, black ink, can be used instead of one or the other or even both of the confusion patterns 32 and 34.
In the preferred embocliment of the invention the confusion patterns 32 and 34 are printed with ink that provide the same general appearance as the play indicia when the game card 10 is candlsd. In some cases due to materials used in constructing the card 10, it is possible that the confusion patterns 32 and 34 may have to be of a different color or print type in order to match the play indicia 10 when candled.
The use o~ either permanent confusion pattern 32 or the removable confusion pattern 34 or a combination of both in the game card 10 can substantially improve game card security while at the same time decrease the costs of manufacturing the cards 10. Additional security is provided by using solvent responsive inks for the confusion patterns 32 and 34 as described above. As a result the invention, as described above, now makes it possible to produce relatively inexpensive paper game cards having a high degree of ' security.
