  • a forgery-resistant document such as a banknote, a passport, an identity card or the like
  • security documents such as banknotes, passports, identity cards or the like, which use plastic films or layers containing security images and applied to protect previously created security elements.
  • One of the elements that have been attempted recently is the creation of a hole with a known graphic shape on a banknote, placed in register with a thread mark, according to the production tolerance.
  • a continuous stripe with holographic demetallised images is then placed over a part of the banknote where the hole is made. At least one of the images is placed inside the hole itself.
  • the stripe is actually made of a plastic polyester tape on which images and/or holographic and/or demetallised graphic signs are created. These images are joined to the plastic support and thereafter it is all applied in register over a paper sheet of the banknote to also protect the hole itself.
  • these thicknesses are considered to be indispensable to bear a whole series of thermal and mechanical stresses caused by the various embossing phases, placed in register between the holographic image and the demetallization, further burdened by the in-register application and fixing around the hole, which fixing is made at about 160 0 C to allow the heat issued from heating cylinder to "cross" the stripe and activate thermo-adhesive to fix the stripe on the paper sheet.
  • a stripe created in this way sets off a series of problems that can bring about the total rejection of banknote production since it may cause unacceptable costs which are around 50% of the overall production costs. For example, "loading" the paper by various processing phases, such as offset copperplate printing of numbering and cutting, in addition to checking in selecting machines, lead to a huge percentage of rejections. Further developments of the stripe created in the above way have been almost exhausted, as it is then hardly possible to keep all the printing phases under control. A particular problem is, for example, transverse and longitudinal undulations under which the paper sometimes suffers after the stripe is applied and cut into sheets for printing. In addition, the later worldwide circulation of banknotes that would then undergo severe undulation, affects all necessary accounting and verification stages at a later stage.

In particular, the present invention relates to security documents such as banknotes, passports, identity cards or the like, which use plastic films or layers containing security images and applied to protect previously created security elements.
It is a known fact that the fight against the forgery of security documents such as banknotes involves companies that are at the forefront of creating the security documents, and consequently in creating new elements aimed at this purpose.
One of the elements that have been attempted recently is the creation of a hole with a known graphic shape on a banknote, placed in register with a thread mark, according to the production tolerance. A continuous stripe with holographic demetallised images is then placed over a part of the banknote where the hole is made. At least one of the images is placed inside the hole itself.
In this case, the stripe is actually made of a plastic polyester tape on which images and/or holographic and/or demetallised graphic signs are created. These images are joined to the plastic support and thereafter it is all applied in register over a paper sheet of the banknote to also protect the hole itself. Several problems have emerged in the realisation of this element having the holographic and demetallised stripe with images in register with each other and with the thread mark at a fixed point on the banknote by in register application on the paper sheet. These problems can be summarized as follows .
Up to now, the realisation of an in-register demetallised holographic stripe with applied in turn in register with the thread mark and protecting the hole which is also in register, has been carried out with a plastic polyester support with thicknesses ranging from 14 to 16 micrometer (while those for transfer from the plastic support to the banknote without a hole range from 23 micrometer for the stripes to 19 micrometer for the patches) . This support uses thicknesses of this type in various work phases, such as coating of lacquers dedicated of receiving embossing in order to create holographic images, together with the various protective lacquers, added to the thermo-adhesive layer to adhere to the paper support. Consequently, a total thickness of 32 micrometer +/-3 micrometer is created.
To date, these thicknesses are considered to be indispensable to bear a whole series of thermal and mechanical stresses caused by the various embossing phases, placed in register between the holographic image and the demetallization, further burdened by the in-register application and fixing around the hole, which fixing is made at about 1600C to allow the heat issued from heating cylinder to "cross" the stripe and activate thermo-adhesive to fix the stripe on the paper sheet.
However, a stripe created in this way sets off a series of problems that can bring about the total rejection of banknote production since it may cause unacceptable costs which are around 50% of the overall production costs. For example, "loading" the paper by various processing phases, such as offset copperplate printing of numbering and cutting, in addition to checking in selecting machines, lead to a huge percentage of rejections. Further developments of the stripe created in the above way have been almost exhausted, as it is then hardly possible to keep all the printing phases under control. A particular problem is, for example, transverse and longitudinal undulations under which the paper sometimes suffers after the stripe is applied and cut into sheets for printing. In addition, the later worldwide circulation of banknotes that would then undergo severe undulation, affects all necessary accounting and verification stages at a later stage. It was found that this in due to the humidity in the air, wherein the undulations are found to be become worsen by the application of a stripe on one side of the paper sheet. The inventors have found that the material properties of the two materials used (the paper is made of 100% cotton and the stripe support is made of 100% plastic) are changed in totally different ways in a humid environment.
It is an object of the present invention to provide an improved forgery-resistant document, such as a banknote, a passport, an identity card or the like, and method thereof such that high quality of planarity of the forgery- resistant document is obtained and that manufacturing costs thereof are reduced.
The object of the present invention is achieved by the feature combinations of the independent claims.

Optionally, each layer structure of the cover sheet and the sheet element further comprises a layer which provides a barrier against humidity. The barrier layer against humidity may comprise an acrylic and/or polyurethane-based varnish or lacquer.
Preferably, the document sheet comprises cotton paper.
According to another aspect of the invention, a manufacturing method of a forgery-resistant document, such as a banknote, a passport, an identity card or the like, is provided. The method comprises the steps of unwinding a document sheet band from a roll, registering the document sheet band, perforating the document sheet band such that document sheets are formed with a hole at a predetermined position, applying a cover sheet on one surface side of each document sheet to close the hole of each document sheet, and applying a sheet element on the other surface side of each document sheet and opposite to the cover sheet to close the hole of each document sheet from the other surface side.
According to still another aspect of the invention, a manufacturing method of a forgery-resistant document, such as a banknote, a passport, an identity card or the like, is provided. The method comprises the steps of unwinding a document sheet band from a roll, registering the document sheet band, applying a sheet element band on one surface side of the document sheet band, perforating the document sheet band and the sheet element band such that document sheets are formed with a hole at a predetermined position, and applying a cover element on the other surface side of each document sheet to close the hole of each document sheet .
Preferably, the methods further comprise the steps of controlling the tension of the document sheet band, the cover sheet or cover sheet band, and the sheet element or sheet element band before applying the cover sheet and/or the sheet element on the document sheet band, and/or controlling the humidity of the document sheet band before the cover sheet and/or the sheet element is/are applied on the document sheet band, and/or turning the document sheet band by substantially 180° after the cover sheet has been applied from above and applying the sheet element from above, and/or winding the document sheet band after the application step of the sheet element, and/or humidifying of the document sheet band and controlling the humidity of the document sheet band, after the applying step of the sheet element, and then rewinding the document sheet band.
Preferably, during the application steps the humidity, the tension and/or the temperature of the items to be applied are/is controlled.
Preferably, the cover sheet and/or the sheet element are attached to the document sheet by adhesion principles including melt adhesion, glueing, self adhesion, two component glueing, UV-hardening and IR-hardening glueing.
According to the aspects of the invention and the above- mentioned preferred forms, the following effects and advantages are obtained.
It is a major advantage of the invention to provide forgery-resistant documents, such as banknotes, with high quality planarity, i.e. flat paper suited to all printing phases (such as offset-printing, silkscreen, numbering, engraving or the like) .
Since there is the possibility to the security means by two applicable elements (cover sheet and sheet element) , the plastic used for the layer structure of the respective elements can be made at least 40% less thick (for example, 10, 8 or 6 micrometer) compared to the prior art.
During different coating phases of, for example, primer lacquer, protective lacquer and holographic coating phase, the cover sheet and the sheet element may pass through ventilated hoods where the temperature should be 80 - 900C. Such a passage stabilizes the layer structures and allows later embossing steps and application at temperatures, which are on average 20/30% lower compared to the prior art, without deforming the document sheet, the cover sheet and the sheet element.
The temperature for applying the cover sheet or the sheet element to the paper in this case is also considerably lower (at least 20%) as the reduction in the thickness of the plastic material (preferably, polyester) allows the thermo adhesive layer, within the same pressure and contact time, to be activated correctly.
A stripe, patch, tape or the like created in this way, applied in register with the hole on the document sheet, provides a reduced resistance against following the document sheet's movements, due to the change in humidity.
Further, such a stripe, patch, tape or the like, applied to one side of the document sheet in register with the hole and another stripe, patch, tape or the like with the same characteristics also applied in register but on the opposite side of the document sheet, enclose the same between two layers of plastic (for example, polyester) in such a way that they preserve what is inside them and therefore reduce impact with humidity and consequently reduce the undulation of the document sheet. Therefore the aim of obtaining document sheets of paper with a hole in register with a thread mark, over which holographic elements may be applied that are in register with the afore-mentioned hole, is achieved by using two stripes, patches, tapes or the like, whose total thickness is equal to or less than 45 micrometer +/-3 micrometer, in turn applied in register with at least one of them and the hole.
The plastic support layer may provide a support element for creating a stripe, patch, tape or the like before the layer structure is applied on the document sheet, that may contain, for example, holographic characteristics created with Kinegrams on transparent and/or metallic areas (evaporation of airtight aluminum) and then demetallised maintaining a register between the holograph and the demetallization, using the plastic support layer, preferably, of a thickness from 8 to 10 micrometer, and with a total thickness of 16 micrometer, added to the fact that all this must be developed at a set measurement with a tolerance in difference of +/- 0.4% maximum.
These strict measurements may be necessary for a continuous application of the stripe itself on one side of the document sheet, in longitudinal and transverse register with the hole already made in the document sheet and in turn positioned in register with a thread mark. All this leaves the paper flat and workable at all later work stages for production of banknotes, preferably.
The sheet element and/or the cover sheet, in addition to protecting the document sheet, that is applied on the other surface side and opposite to the cover sheet, may also have additional security characteristics such as, for example, fluorescent inks and/or pigments at both 360 nanometers and 254 nanometers and/or inks or pigments that absorb infrared rays and/or pigments or particles that can be detected when agitated with ultrasound or microwaves or with magnetic elements in continuous and encoded mode, using one or more magnetic oxides or inks with different coercitivity and the same reside or different coercitivity and different residue or equal coercitivity and different residue or equal coercitivity and equal residue.
Further elements that can be used in the layer structure of the cover sheet and/or the sheet element are, for example, colourshift pigments or colored pigments that reflect in different ways depending on the angle at which they are hit by the light and at which angle they are observed.
Another example of use of the sheet element and/or the cover sheet may be that of creating a series of layers of materials, such as chrome, magnesium fluoride and aluminum on the plastic support layer and/or plastic film layer that provide color variation, depending on the inclination with which they are hit by the light and then observed.
Summarizing, one of the main innovations of the invention is seen therein that one stripe (the cover sheet) in recto and one (the sheet element) in verso are applied on the document sheet, wherein at least one of the cover sheet and the sheet element is in register with the hole in the document sheet. This solves the problem of having, for example, a stripe (cover sheet, sheet element, patch or the like) including graphic elements and/or visible patterns and/or prints and/or holographic images or the like, which stripe is made up of a polyester support and applied in transverse and longitudinal register to cover a hole in a banknote such that the document sheet, usually made of cotton-based paper, remains flat and therefore it is easily to handle in various production stages of banknote creation. Further, considering bank notes to be used all over in human live surroundings, the maintenance of the flat shape is also important for a good handling of the notes .
It is also possible that both the stripes (the cover sheet and the sheet element) can be applied in register with the hole, or that one only is in register, regardless of whether it is the one in recto or in verso of the document sheet .
Further, it is also preferable that the cover sheet and/or the sheet element when formed as continuous stripes or patches may have the same or different width and/or length depending on the method of application for which, if carried out in two phases, it is advisable to use a larger one for one stripe/patch than for the other one thereof, for example, at least 0.5 mm so that the other stripe/patch, when pressed against the document sheet and fixed therein with an adhesive layer does not have any areas without any pressure peaks. In other words, the outer circumferences of the cover sheet and the sheet element are formed such that they are substantially congruent with each other .
It is preferable that one of the cover sheet and the sheet element may be a release-type member. That is, the layer structures of the cover sheet and/or the sheet element may be created on a support layer, preferably on a plastic film layer, used for the various stages of coating, printing, painting, embossing, metallization, demetallization, etc. Then, after finishing the manufacturing of the desired layer structure, this support layer may be removed or released from (peeled of) the layer structure when the various layer materials are transferred onto the document sheet, for example, during a heat transfer phase. In such a case of using this release-type member, the one of the cover sheet and the sheet element, which is applied first to the document sheet (in register or out of register with the hole) , is such a release-type member; once it has been applied, the document sheet goes on to a perforation station where the hole may be created in register with the thread mark of the document sheet; then, the other of the cover sheet and the sheet element, which is a no-release member (i.e. where the plastic layer remains when the member is fixed on the document sheet) is then applied at a second stage or at a new station on the other surface side of the document sheet and opposite to the release-type member (in register or out of register with the hole) .
According to the invention, a document sheet may be provided which is enclosed in part by stripes, patches, etc. having optionally security characteristics, in particular, enclosed between a cover sheet having a plastic (e.g. polyester) support layer and a sheet element having also a polyester support layer. The layer structures of the cover sheet and the sheet element may further comprise, for example, a thermo-adhesive layer or a self-adhesive layer or a chemical-reactant layer or another adhesive layer, and/or an adhesion primer layer and/or a holographic lacquer and/or a metallization layer and, optionally, a layer which provides a barrier against humidity, etc., wherein the adhesive layer is fixable to the document sheet. The document sheet may be thus enclosed between two layers of polyester or between one layer of polyester and one layer of high wear-resistance polyurethane paint. These two layers of materials and maintain the surface tautness or tension of the two sides of the document sheet unchanged and do not allow undulation due to humidity and the unbalancing of surface tautness on one of the two surface sides of the document sheet itself.
It is further preferable that the above-mentioned layer structures of the cover sheet and the sheet element comprise at least one layer which provides a barrier against humidity. Such a barrier layer against humidity may comprise an acrylic and/or polyurethane-based varnish or lacquer or the like.
The manufacturing method of the forgery-resistant document according to the invention is preferably used for two stripes, bands, items, etc. applied one in recto and the other in verso of the document sheet, one at least of which in register with a hole perforated in the document sheet.
The method may comprise use of an equipment made up of devices and means including, for example, a document sheet unwinder roll, a dragging unit that advances the paper according to a preset constant speed, a first paper humidification station so that a band or tape application always takes place at a controlled temperature and humidity, a perforation station where the holes are made (one in each document sheet) in register with the thread marks thereof, a band or tape application station preferably comprising a cylinder with a diameter of at least 400 mm heated by electrical coils or diathermic oil and suitable for applying pressure of about 50 - 60 N per linear cm. A series of rolls whose contact surface with the band or stripe is in 316L steel, lapped and preheated by thermal induction from another cylinder that is heated by diathermic oil or electrical coils. The document sheet band that may unwind around the heated cylinders and have said band or stripe placed between the cylinder and the document sheet band and a second band or paper that is positioned past the application station of the first band or tape in the document sheet transfer direction, is thus arranged between the document sheet band itself and the counter- pressure rolls. It should be clear that the pressure and the temperature of each roll can be regulated individually, even with significant differences, as is also the case for the cylinder temperature, which can be regulated by sectors. Further, the used materials for the rolls and cylinders are merely exemplary, thus any materials suitably for the above mentioned conditions can be used. A explanatory process for manufacturing a forgery-resistant document may comprise the steps/sections in the following order: 1 - unwinding section of the document sheet band, 2 - registering of the document sheet band such that a linear run of the document sheet band through the different manufacturing steps is achieved, 3 - controlling tension of the document sheet band, 4 - section for humidify, 5 - application section of cover sheet tape, band, patches or the like with controlling the tension of the tape, preferably either the tape may be heated when thermo- adhesive is used or a self-adhesive band may be used, 6 - perforating the hole, 7 - turning the document sheet band, 8 - application section of sheet element tape, band, patches or the like in longitudinal and transversal register with the hole, 9 - optional section for humidify, and 10 - rewinding section.

Fig. 4 shows an example of a constitution of a layer structure of the cover sheet or the sheet element.
A preferred embodiment of the present invention is now described with reference to Fig. 1 to 4.
According to Fig. 1, a bank note 1 as a document sheet has a rectangular form. The bank note 1 comprises a hexagonal hole 2 and a circular watermark 3. Any geometrical forms of the hole 1 and the watermark 3 may be used. The hole 2 is formed within the bank note 1 at predetermined position in respect to the watermark 3 and to the outer circumference of the bank note 1.
A cover sheet 4 which may include several security means such as holographic pictures, Kinegrams, metallic areas or the like, which are schematically shown by a sun-shaped item, a hexagonal pattern 41 and triangular-shaped forms has to be applied on the surface side of the bank note 1.
As it is shown in Fig. 2A und 2B, the cover sheet 4 is applied on the respective surface side of the bank note 1 such that the hole 2 is closed by the cover sheet 4 and the hexagonal pattern 41 of the cover sheet 4 is in register with the hole 2. Thus, the cover sheet 4 itself is in register with the hole 2. As it is further shown in Figs. 1, 2A and 2B, the cover sheet 4 consists of a rectangular stripe, which is applied along a transverse side direction of the rectangular bank note 1 on the respective surface side .
In Figs. 3A and 3B, the bank note 1 has been turned around 180° such that the bottom surface of the bank note 4 lies now on top in Fig. 3B. As it is shown in these figures, a sheet element 5 is applied on the other surface side, i.e. the bottom surface, of the bank note 1 and opposite to the area where the cover sheet 4 has been applied to the top surface thereof. Thus, a high quality of planarity of the bank note 1 is achieved since the cover sheet 4 is applied in recto (i.e. on the top surface) and the sheet element 5 is applied in verso (i.e. on the bottom surface) on the bank note 1.
The sheet element 5 may also include security means such as a holographic item or the like which is in register with the hole 2, as it can be seen from Fig. 3A. Also the sheet element consists of a continuous stripe, which is applied along the transverse side direction of the rectangular document sheet on the bottom side of the bank note 1. Fig. 4 shows an exemplary layer structure of the cover sheet 4 or sheet element 5, which comprises a thermo- adhesive layer, a metallization layer, a holographic lacquer, an adhesive primer layer and a plastic film layer, in particular, a polyester film layer, in this order from the bottom to the top, wherein the thermo adhesive layer is fixable to the bank note 1.
While the invention has been described with reference to the preferred embodiment disclosed above, the invention itself is not confined to the details set fourth in accordance with this embodiment and this application is intended to cover such modifications or changes as may come within the scope of the following claims.
