Definitions

  • This invention relates to security printing of articles, whereby the authenticity of the article can be checked subsequent to its manufacture.
  • the invention has particular, although not exclusive, application to the printing of tickets, cards and the like articles.
  • Tickets, such as lottery tickets, and cards, such as prepaid telephone cards have a value much greater than the value of the materials from which the tickets or cards are constructed, and hence they are attractive to the fraudsters because if such fraudsters can reproduce the cards and sell them at their normal or even lesser prices, then there is considerable illegitimate profit to be made. In consequence, much effort and time has been put into providing such cards and tickets with security devices, such as hidden codes, layers of foil material (so that the fraudster cannot see through the tickets or cards using strong light) and other devices.
  • thermochromic layer which is printed on the ticket or card.
  • a thermochromic ink layer is one which essentially changes colour, but the word thermochromic hereinafter is to be taken to mean the ability of an ink to change one or more of its physical characteristics such as colour, translucency, optical variability or transparency during the application of heat thereto or the extraction of heat therefrom.
  • the basic idea is that the thermochromic layer will cover a validation mark or symbol word or other device and if the purchaser of a ticket wishes to validate the ticket he simply places a finger or thumb on the thermochromic ink, which loses its colour or becomes transparent and the security mark is revealed. When the heat of the finger or thumb is removed, the thermochromic layer returns to its original state again concealing the security mark.
  • This invention seeks to provide a security arrangement for articles, which has a high degree of security.
  • a security feature on an article comprising a first validation means printed in a first thermochromic ink having a physical characteristic which changes at a first activation temperature, and a second validation means printed in a second thermochromic ink having a physical characteristic which changes at a second activation temperature, characterised in that one of the inks has an activation temperature between an ambient article temperature and human body temperature such that the application of a human finger over said security feature alters the appearance of said security feature in a first manner noticeable to the naked eye, the second activation temperature being different from that of the first ink which results in an alteration of the appearance of said security feature in a second manner when said security feature is cooled or heated to a temperature lesser or greater than the second activation temperature.
  • the activation temperature of one of the inks is substantially equal to human body temperature.
  • the second ink is printed at least partially over the first ink and the security feature is defined in the overprinted region.
  • thermochromic ink layers are of different colours such that the validation means is manifested in a colour change in the security feature.
  • the security feature includes an image printed in a solid ink on the article which is obscured at least partially by one or other of the said thermochromic layers.
  • the image may also be printed in a thermochromic ink.
  • the solid ink image is printed directly one the article, the thermochromic ink layers being provided thereover.
  • the solid ink image is printed over a first of the thermochromic layers and beneath a second thermochromic layer so as to be disposed between said layers.
  • thermochromic ink layers are printed in a particular pattern to define at least one validation mark which appears, disappears, becomes more or less visible, or changes colour on application of a human finger.
  • the second activation temperature is higher than that of the thermochromic ink having an activation temperature equal to the human body temperature.
  • one of the thermochromic ink layers may be cryothermic in that its activation temperature is below 0°C, or at least much lower than human body temperature.
  • thermochromic ink layer is cryothermic.
  • thermochromic ink layer having the lower activation temperature is disposed beneath that having the higher activation temperature.
  • the ultimate user can check the security of the article by applying a finger or thumb to the security printed area, which has the effect of rendering the second layer transparent, in the preferred colourless, so that the validation mark becomes visible.
  • This will usually be acceptable to the user, but should it be that the manufacturer, the customer for the articles, or the agent who distributes the articles, wishes to perform additional security check, then he can do so by heating up (or freezing) the article in the region of the security feature.
  • the heating may be done simply by placing the article on a conventional central heating radiator, or by using a hot air producing device, such as a hair dryer.
  • the first thermochromic ink may be of such a nature that a physical characteristic of the ink changes at a temperature in the region of 37°C, whilst the second thermochromic ink may be of such nature that it becomes transparent or translucent at a temperature in the order of 27°C for use in countries, such as the United Kingdom, which have temperate climates, but these temperatures are only guides as the activation temperatures can be varied as required. For example, it the article is to be tested in a cold climate or a hot climate, then inks with appropriate activation temperatures different from the above may be needed. Obviously, there should be a sufficient gap between the activation temperatures of the two layers, to ensure that the first ink is not activated by the thumb or finger heat.
  • the activation of the first ink by the application of heat will also cause activation of the second ink.
  • the second ink may preferably be of the type which reverts to a condition in which it obscures the validation mark, but the ink of the first layer need not be revertable. When it is activated by heat, the change may be permanent.
  • thermochromic ink layer may be formulated to include a fluorescent or iridescent material so that it will fluoresce when activated. Thus even if the colour of the validation mark disappears when heat is applied, the mark may still fluoresce when subjected for example to ultra violet light
  • the second ink may also be modified so as to make it "optically variable", which means that it has a different appearance when viewed in different directions. This is achieved in one example, by the use of platelets in the formulation. This optical effect is similar to the effect achieved by holographic printing.
  • the invention has particular application to rendering more secure articles such as lottery tickets, and telephone cards, especially the latter, but it will be clear that it can be applied to any article the checking of the security of which by the means of the invention, provides an advantage.
  • the cards When the invention is used as security means in connection prepaid telephone cards, the cards may be sold in a clear wrapper, and the activation of the first ink using a finger or thumb, can be effected through the wrapper, which is a considerable advantage as a purchaser can test the validity of the card without removing the wrapper.
  • This provides extra security, as it is not unknown for fraudsters to photocopy genuine card and simply photocopy them and sell the photocopies, and it is only when the user tries to use the card that he finds out that it is a fake.
  • thermochromic ink layers are of different colours, e.g. blue and yellow
  • the inactive colour of the security feature will be green.
  • the application of a human finger will cause a first colour change from green to blue as the yellow layer loses its colour, whereas raising or lowering the temperature of the security feature to the second activation temperature may result in a colour change from green to yellow.
  • the blue layer changes state.
  • thermochromic layers themselves may be printed in certain patterns defining a validation mark.
  • the invention thus arises as a result of the interplay between the two thermochromic layers.
  • the invention thus provides two levels of security.
  • the first level provides for easy, quick and simple verification that the ticket is genuine, and this security feature may even result in the articles themselves being popular as the public can verify said tickets.
  • the second level of security would not be disclosed to the public so manufacturers and the vendors of the articles could perform a second check to establish whether a suspect ticket was genuine.
  • thermochromic inks A wide variety of thermochromic inks is now available and in colours essentially identical to the colours of conventional printing inks. Solid ink images can therefore be totally obscured by colour matching with the thermochromic ink, and variation in film weight of the thermochromic layer (which is easily achievable because the thermochromic ink can be printed by any conventional commercial printing method) results in more or less rapid activation as required.
  • a telephone card 10 is of conventional construction, but additionally is provided in an area 12 with the security printing according to the invention.
  • the card 10 in this example may be contained for example in a clear material wrapping 14, for added security in that the wrapping must be removed before the card can be used.
  • a suitable code which identifies the manufacture and/or batch number of the card for the second layer of security checking as is explained to you hereinafter.
  • the card 10 comprises a substrate 16 of conventional construction, and it may comprise paper, plastic, foil or paper/plastic/foil laminate in any combination, or other suitable material.
  • the security printing 12 On the surface of the card 16 is applied the security printing 12, and this printing comprises a first layer 18 of a first ink which is thermochromic in nature and may also have a fluorescent additive.
  • the first layer 18 defines the validation mark for the card, and this is covered by a second thermochromic layer 20 which also is optically variable as discussed above, again for added security.
  • the layer 20 as shown in Fig. 1 covers all of the area 12 and its function is to obscure the layer 18 from view, but the thermochromic nature of the layer 20 is such that the obscuring capability of the layer 20 can be removed by the application of a finger or thumb 22 as shown in Fig. 3 to the area 12.
  • the heat from the finger or thumb causes the obscuring nature of the layer 20 to be removed so that it becomes, in known manner, translucent or transparent so that the validation mark 18 becomes visible, as shown in Fig. 4.
  • the layer 20 will revert to its original colour, once more obscuring the validation mark.
  • the validation mark be printed in the same colour or a matching colour to that of the obscuring layer 20 to ensure maximum obscuring effect, but this is not necessary in all embodiments of the invention.
  • the layer 20 may be adapted to be activated, that is to become translucent or transparent at a temperature selected depending upon the climate in which the article is to be used, and for moderate climates the activation temperature may for example be in the region of 27°C.
  • thermochromic nature of the validation mark 18 is such as to be activated at a substantially higher temperature, for example in the order of 37°C when ink 20 is activated at 27°C.
  • the ticket can therefore be checked to a second level of security by heating it beyond the activation temperature of the layer 20, and when such heating takes place, for example by heating the ticket with a hot air blower or simply putting it on a radiator of a conventional central heating system, the validation mark eventually in this embodiment disappears as shown in Fig. 5, thereby providing a second level of security.
  • the ink which is used for the validation mark 18 may also contain a fluorescing material so that even in the condition shown in Fig. 5, the validation mark can be examined by using for example an ultraviolet source in which case the validation mark will appear in a fluorescent print form.
  • thermochromic inks which are used in the present invention may need to be specially formulated, but there are available commercially thermochromic inks which operate in the manner described and are active at different temperatures, and these can be used in the instant invention.
