Abstract
There is disclosed a security printing system. Two layers of thermochromic ink are applied to the article each having a different and sufficiently separate activation temperatures at which a certain characteristic of the ink changes. The first applied layer, in the shape of a validation mark or the like, ideally has an activation temperature higher than the second layer applied thereover, so that two separate tests can be performed on the article, A first test is the application of heat to the mark by a human finger at the like whereupon the second layer becomes ideally transparent to revel the validation mark. The second test as the application of more heat, whereupon a particular characteristic of the first ink changes.
Description
The present invention relates to the anti-fake printing system of article, can after article production, differentiate its true and false by the present invention.
The present invention is having special purposes aspect the printing of bill, card and similar articles, and can be used for other field.
Bill (as taking out lottery ticket) and card (as phonecard of advanced charge etc.) all have the much higher value of cost than bill or card manufactured materials, so they often become adulterator's target.If the adulterator can duplicate these bills or card and according to its normal price even be lower than normal price and sell, just can illegitimately make exorbitant profits.Therefore, people have spent bill and the card that a large amount of time and energy manufacturing have imitative pseudo-device.Existing imitative pseudo-device comprises implicit code, layer of metal foil (preventing that the adulterator from utilizing high light to see through bill or card) and some other devices.
The thermochromic layer that known one of adopted device prints on bill or card exactly.The thermal color-changing printing ink layer is a kind of color shifting ink in essence, and " thermo-color " used herein speech refer to printing ink be heated or meet cold in a kind of ability of changing of its one or more physical propertys such as color, translucence, optical change or the transparency.Its basic ideas are that affirmation mark, sign word or other pattern are covered with thermochromic layer.If whether bill buyer wants to confirm bill is true, only need finger is pressed on thermal color-changing printing ink, thermal color-changing printing ink will lose color or become transparent, thereby anti-fake mark will reveal.After the heat of finger left, thermochromic layer recovered former state, and anti-fake mark can be hidden again again.
Unfortunately, fake and not only occur in the operational phase of bill or card, even just taken place at manufacturing and distribution phase more early.For example, an immoral card dealer can pseudo-produce and have a whole set of card or the bill that finger is confirmed function.Therefore, be badly in need of other false proof measure, whether have fraud to take place for example to check, thereby increase security in manufacturing and distribution phase.
The objective of the invention is for article provide a kind of safe Antiforge system, it can reach higher level of security.
According to the present invention, the Antiforge system that is provided on the article comprises that first confirms the device and the second affirmation device, and first confirms that device uses first kind of thermal color-changing printing ink printing, and this first kind of thermal color-changing printing ink its physical property when first activation temperature changes; Second confirms that device uses second kind of thermal color-changing printing ink printing, this second kind of thermal color-changing printing ink its physical property when second activation temperature changes, wherein, a kind of activation temperature of printing ink is between the ambient temperature of article and people's body temperature, thereby when people's finger acts on the above-mentioned Antiforge system, the outward appearance of this Antiforge system changes in first kind of mode, and this variation is that naked eyes can be awared; And the activation temperature of second kind of printing ink is different with the activation temperature of first kind of printing ink, thereby when this Antiforge system is cooled to below or be heated to above the activation temperature of second kind of printing ink, the outward appearance of this Antiforge system will change with the second way.
Preferably, wherein a kind of activation temperature of printing ink and human body temperature be about equally.
Preferably, second kind of printing ink covers first kind of printing ink in printing up to small part, and Antiforge system is positioned at the printing overlapping areas.
Preferably, the color difference of two kinds of thermal color-changing printing ink layers, thus make in Antiforge system and to confirm that device displays with the form of change color.
Preferably, Antiforge system comprises that is used the pattern of pure color ink printing on article, and this pattern can be hidden by the part of above-mentioned two kinds of thermochromic layers at least.Alternatively, this pattern also can use a kind of thermal color-changing printing ink printing.
Preferably, the pure color pattern directly is printed on the article, and the thermal color-changing printing ink layer is printed on the pattern.Perhaps, the pure color pattern is positioned on first thermochromic layer, under second thermochromic layer, thereby be clipped in two-layer between.
In a kind of alternative embodiment, wherein a kind of or whole two kinds of thermal color-changing printing ink layers all print in a kind of specific mode, thereby can define at least a affirmation mark, this affirmation is marked at the finger that is subjected to the people and does the time spent and can show, disappear, become more obvious or fuzzy or change color.
Preferably, the activation temperature of second kind of thermal color-changing printing ink is higher than the activation temperature of the thermal color-changing printing ink that activation temperature equates with people's body temperature.Perhaps, wherein a kind of thermal color-changing printing ink layer is " low temperature properties ", and promptly its activation temperature is lower than 0 ℃ or at least far below people's body temperature.
Advantageously, the thermal color-changing printing ink layer of the superiors is low temperature properties.
In a preferred embodiment, the thermal color-changing printing ink layer that has than low activation temperature is positioned under the thermal color-changing printing ink layer with high activation temperature.
Article with imitative antiforge system of the present invention in use, the end user can check the security of article, the user only needs a finger (as thumb) by in the anti-fake printing zone, and the second layer will bleach (preferably colourless), thereby the user can see the affirmation mark.For the user, generally can both accept this system.But for the distributing mechanism of manufacturer, order unit or article, they wish to carry out more safety inspection.At this moment, they can heat the zone at Antiforge system place or cool off.Only need during heating article are placed on the common radiator, or use hot-air generating means such as hair dryer to get final product.
Certain physical property of first kind of thermal color-changing printing ink may change in the temperature range about 37 ℃, and for the more such countries that have a moderate climate of Britain, second kind of thermal color-changing printing ink may become transparent or semitransparent about 27 ℃.The numerical value of these temperature only plays directive function, because people can change activation temperature according to the needs of oneself.For example, if these article need be accepted test under cold or hot weather conditions, so just need the activation temperature printing ink different with above numerical value.Any is arranged is conspicuous, and that is exactly that the activation temperature of two kinds of thermal color-changing printing ink layers will have enough big difference, activates to guarantee the heat that first kind of printing ink is not pointed.
To activate second kind of printing ink simultaneously during first kind of printing ink of heat-activated.Second kind of printing ink preferably can return to after heat is removed and hide the state of confirming mark, but first kind of printing ink there is no need to have this specific character.The variation that first kind of printing ink is subjected to cause after the thermal activation can be nonvolatil.
In order to increase security, any thermal color-changing printing ink can add fluorescent material or iris material when preparation, thereby after its activation fluorescence can take place.Therefore, even confirm that when heating the color of mark has disappeared, it still can send fluorescence when being subjected to such as action of ultraviolet ray.
Can carry out suitable improvement to second kind of printing ink,, have different outward appearances when promptly observing from different directions so that it has " optical variability ".This can realize by use platelet when preparing printing ink.The effect of its optical effect and holographic printing is similar.
The present invention can be used for making the higher article of security, as draw tickets and phone card, the especially latter.Obviously, the present invention also can be used for the safety inspection of other article, and it is more more superior than other device.
When the present invention was used as the false proof device of advance payment phonecard, phonecard can be contained in the transparent packaging bag and sell.Finger just can activate first kind of printing ink across packaging bag, and this brings very large benefit, because buyer can differentiate the true and false of card under the situation of not removing packaging bag.Can increase the security of card like this, because the adulterator often sells the user with the copy of true card, and the user has only and just realizes when bringing into use phonecard and have dust thrown into the eyes.
It is pointed out that according to the present invention, unnecessary pattern or the affirmation mark that in Antiforge system, comprises any pure color ink printing, the affirmation article genuine-fake can only be checked the change color in the certain zone of above-mentioned article.For example, if the thermal color-changing printing ink layer has different colors, as blue and yellow, Antiforge system will be green when not activating so.After the effect of the finger that is subjected to the people,, promptly become blueness by green because the fade of Yellow ink layer will produce first kind of change color; When the temperature in Antiforge system zone rose or is reduced to second activation temperature, the fade of blue ink layer will produce second kind of change color, promptly becomes yellow by green.Those skilled in the art person is appreciated that if below these two kinds of thermochromic layers or middle the third color that adds, will produce many permutation and combination, thereby the mode of printing of thermochromic layer itself just can defines a kind of affirmation mark.In one embodiment, the present invention has just utilized results of interaction between two kinds of thermochromic layers.
Therefore, the invention provides the two-stage level of security.First order level of security can easily and fast, simply be differentiated the true and false of bill.Because the public differentiates the true and false of bill easily, this Antiforge system can make article itself more general.Second level level of security can not announce that article manufacturer and distributors can carry out second kind of inspection to the public, to determine the true and false of bill.
Thermal color-changing printing ink in the market is a lot, its color also with common printed color of ink basically identical.Therefore the pure color pattern can be hidden by the identical thermal color-changing printing ink of color fully, and the printing ink of activation can print by any common commercial printing process, regulates the thermochromic layer film thickness and is easy to accomplish.
Below in conjunction with illustration, the mode by example is described one embodiment of the present of invention, wherein:
Fig. 1 is the vertical view that is provided with according to a phonecard of imitative antiforge system of the present invention;

With reference to the accompanying drawings, phonecard 10 adopts traditional structure, just additionally is provided with the zone 12 that has Antiforge system of the present invention according to the present invention.In this embodiment, card 10 can be contained in the transparent packaging bag 14, because packaging bag must be removed before phonecard uses, this way makes phonecard increase security.In another one zone 16, a number that matches with card is arranged, in order to differentiate the lot number of manufacturer and/or card in the safety inspection of the second level, its concrete steps will be described hereinafter.
As shown in Figure 2, card 10 includes the bottom of ordinary construction, and this bottom can comprise thin slice or other material that paper, plastics, metallic film or paper/the plastic/metal film combinations is got up.Be provided with anti-counterfeit printing zone 12 on the surface of card 10, it includes first thermochromic layer 18, and this layer has thermochromism, also may contain fluorescence additive.First thermochromic layer 18 has defined the affirmation mark of card.Be second thermochromic layer 20 on it, it has above-described " optical variability ", to increase the security of card.
Among Fig. 1, thermochromic layer 20 has covered the whole of zone 12, and its function is from visually hiding thermochromic layer 18, but the thermo-color characteristic of thermochromic layer 20 make when be subjected to pointing 22 do the time spent it will no longer have the covering effect to regional 12, as shown in Figure 3.The heat of finger makes thermochromic layer 20 forfeiture covering effects, become transparent or semitransparent, thereby confirm that mark 18 reveals, as shown in Figure 4.After finger shifts out, in predetermined, thermochromic layer 20 will return to original color, hide again to confirm mark 18.Preferably, confirm that the color of the color of mark and thermochromic layer is identical or close, reaching best covering effect, but this point is not all to be necessary to all embodiment of the present invention.
The activity function of thermochromic layer 20 can make it to become under chosen temperature transparent or semitransparent according to the weather change of article use.For example for the weather of gentleness, its activation temperature can be chosen in about 27 ℃.
Confirm that 18 of marks should activate under a higher temperature.For example, when the activation temperature of thermochromic layer 20 was 27 ℃, its activation temperature should be about 37 ℃.
Therefore, bill can be heated to, bill is carried out second level safety inspection than the higher temperature of thermochromic layer 20 activation temperatures.Heating can be used hair dryer, also can confirm that at this moment mark will disappear, as shown in Figure 5 with common radiator.Like this, just make bill have second level security.
After the card cooling, confirm that mark 18 will restore to the original state, thermochromic layer 20 restores equally, and card is finally got back to state shown in Figure 1.
In order to reach higher security, can be used for printing a kind of fluorescent material of printing ink interpolation of confirming mark 18, thereby, also can use and check the affirmation mark such as ultraviolet ray even under situation shown in Figure 5, confirm that mark can send fluorescence this moment.
If meet forged note, the user can be placed on finger and differentiate its true and false on the zone 12 rapidly.If bill has passed through the finger test but not by second test, just can utilize code 16 to determine the source of counterfeit.
These measures can reduce the forgery behavior of this type of card and bill, and can be used for the article that other need check authenticity.
The thermal color-changing printing ink that uses among the present invention may need special preparation, but dares on the market that the ready-made thermal color-changing printing ink that activates under different temperatures is arranged.These printing ink can be directly used among the present invention.
