Abstract
A security document (1), such as a banknote is formed from a sheet-like substrate (10) of clear plastics material with layers (13, 14, 15, 16) of opacifying ink applied to the surfaces (11, 12) of the substrate (10). The security document (1) includes a security device (20) which is at least partially obscured by the layers (13, 14) of opacifying ink on a first surface (11) of the substrate (10). The layers (15, 16) on the second surface (12) of the substrate (10) are applied in such a manner so as to leave a "half-window"
area uncovered by opacifying ink through which the security device (20) is visible from one side of the document (1). The security device (20) may extend transversely outside the half-window area and be visible in transmission, enabling a different contrasting effect to be observed from both sides of the document.

Description
BANh'N(JTBS IN~ORPC~RATTNG ;~fBC~IRITY D1VI~:~:>~S
This invention relates to security documents, such as banknotes or the like, and is particularly concerned with providing a security document formed from a plastic substrate with an enhanced secut°ity device..
j In PC:'r flpplieatioo WO ~3'i/OUGS~) (LMI'RO°VT;T) L~~:NKNC.'~'1'LS
,~NL) 'T'1-LF 1..1KE) there is disclosed a sccurit.y document and a n~ethad o:f:' I~rac.~iu~;iro;' a security <lc:~cu~ncW, i.1 v~lvich upacifying coatings of ink are applied to both sides of a sheet-like. substr ate formed from a clear plastics film. The security document ~rtay be produced with some areas to which o0 opacifyin~,~ coating i~> apf~liecl are Loth sidca of tric; clew plastics substrate. These clear, transl?arena ~~teas~ art;:: krruwta as "windows" arid are particularly suitable f'or incorporatin4~ securit:yf de~~ices, for e~arople difl~f-action gratings, optically variable devices and embossed images, which can be inspected in the transparent areas or windows 1'rarr~ both sides of the security down m.nt.
IToweve.r, a secm.~ity device, suci~ as a cli:l~fi~~~ction gz;a~..in~> in ~u vrindcaw geni;rally has tlne same appc;arancc; wht~n viwvod i~rann bot:i~ side.; r~l~ thr: sucurity~
document.
It is therefore: desirable to provide a secu~~ity ~Ioci.uuc:nt which incorporates a security device that presents a different app~a~rantr~. fuon~ opposite sides of the;
document.
It is also desirable to provide a security d~~otin~mnt fortntTd from a ~le~:r plastics substrate with an enhanced forf~n of secuw;ity device.
It is further desirable to provide a relatively simple method of pravidin~; a security document with <~n enhanced farms of security cicvice.
a'ccordinp to at~c; aspect caf' the invcrltion, tho:re is hro,,~itied a security document comprising:
a sheet-like substrate of clear plastics material having first and second surfaces on apposite sues of the substrate;
said substrate having a region including a secctrity device;
at. least one layer of apac;ifying i.nk applied on a fiF~st sido of the substrate and at least partially obscuring said security device from one side of the substrate: and at least one layer of' apacifyino ink aLrplied an tire opposite side of the substrate in such a manner as to leave an area on said opposite side ~.~~hich is not ~i i covered by the opacifying ink substantially in the region including the security device.
According to another aspect of the invention, there is provided a method of producing a security document comprising the steps of:
providing a sheet-like substrate of clear plastics material having first and second surfaces on opposite sides of the substrate;
said substrate being provided with a security device in at least one region of the substrate;
applying at least one opacifying layer of ink on a first side of the substrate so as to obscure said security device from one side of the substrate; and applying at least one opacifying layer of ink to part of the opposite side of the substrate in such a manner as to leave an area which is not covered by ink substantially in the region of the security device.
Preferably, the layers of opacifying ink are applied directly to said first and 1S second surfaces of the substrate.
In the security document and method of the invention, the area of the second surface of the substrate which is not covered by the opacifying ink forms a "half-window" through which the security device may be inspected from one side of the substrate, the security device being at Ieast partly obscured by the opacifying ink when viewed from the opposite side of the substrate. Thus the security device has a different appearance when viewed from opposite sides of the document.
For instance, the security device may be clearly visible in the half-window from the side of the second surface of the substrate, but not visible or only partially visible, eg. only in transmission from the side of the first surface of the substrate.
Preferably, the security device is more visible in transmitted light than in reflected light from the side of the first surface of the substrate.
The security device may be formed within the transparent plastics substrate.
Alternatively, the security device may be applied to at least one of the first and second surfaces of the substrate.
In the method of the invention, the steps of applying the security device and of applying the layers of opacifying ink to the first and second surfaces of the substrate may be performed in different orders. For instance, the step of applying at least one layer of opacifying ink to part of the second surface of the substrate to form the half-window may be performed first before the steps of applying the security device to the substrate in the region of the half-window and of applying at least one opacifying layer to the first surface of the substrate to obscure the security device.
Preferably, however, the step of applying the security device to the substrate is performed prior to the steps of applying the layers of opacifying ink to the first and second surfaces of the substrate which may then be performed either simultaneously or one after another.
Preferably, part of the security device extends transversely outside the area of the "half-window" which is not covered by the opacifying ink on the second surface of the substrate. Preferably, the part of the security device which extends outside the area of the half-window is more visible in transmitted light than in reflected light. When a security device is provided in a banknote or security document in this manner, different parts of the security device may present different effects to a viewer from each side of the banknote or security document. For instance, if the layer or layers of opacifying ink only partially obscure the security device, the part of the security device outside the half-window area may be visible, at least in transmission, but not as apparent as the part of the security device within the area of the half-window. It is therefore possible for different contrasting effects to be observed between relative visibilities of the different parts of the substrate from both sides of the security document.
A wide variety of security devices may be employed in the present invention.
Examples of the type of security devices which may be applied to the substrate in the present invention include: fine line or filigree patterns; micro-text;
security stripes or threads; front and rear registration devices, including Moire patterns;
embossings; diffracting gratings; optically variable devices; coloured, fluorescent, phosphorescent and pearlescent inks and optically variable inks; metameric inks, and coloured filters which may be used to view such inks.
When the security device comprises a front to back registration device, such as a Moire pattern, different parts of the device may be applied to the first and second surfaces on both sides of the clear plastics substrate before the opacifying layers of ink are applied.
Alternatively, the security device may comprise a taggant provided within the substrate. The taggant may be invisible to the naked eye, but readable by a reading device through the half-window from the side of the second surface of the substrate.
In one embodiment of the invention, the security document may have a plurality of half-windows which are not covered by opacifying ink. The plurality of half-windows may be provided on both sides of the substrate. For instance, both the first and second surfaces of the substrate may have half-window areas at different transverse locations that are not covered by opacifying ink, said half-window areas being arranged alternately on the first and second surfaces of the substrate. A continuous security device, such as at least one security stripe or thread may extend through the half-window areas to give the appearance of a stripe or thread weaving through the substrate.
In order that the present invention may be more readily understood, various embodiments thereof will now be described, by way of example only, with reference to the accompanying drawings, in which:
Figure I is a sectional view through part of a security document in accordance with the invention;
Figure 2 is a view from one side of the security document of Figure 1;
Figure 3 is a view from the opposite side of the security document of Figure 1;
Figure 4 is a sectional view through a security document in accordance with the invention incorporating a security thread;
Figure 5 is a view from one side of the security document of Figure 4; and Figure 6 is a sectional view through a security document in accordance with the invention incorporating a front-to-rear registration device.
In Figure 1, there is shown a security document 1 comprising a sheet-like substrate 10 of clear plastics material having a first, lower surface 11 and a second, upper surface 1?, layers 13 and 14 of opacifying ink applied on the first, lower WO 98/13211 PCT/AU97/0063?
surface 11 of the substrate 10, layers of opacifying ink 15 and 16 applied on the second, upper surface 12 of the substrate 10, and a security device ?G on the lower surface 11 of the substrat-~ 10 between the substrate 10 and the layer of opacifying ink 13.
As shown in Figure 1, the opacifying 1<zyers of irrk 1S and 16 arw not applied over the entire upper surface 12 of the substrate ~ () and thus leave an area of the second, upper surface 1.:.' which is not cowered l:zy opacifying ink to form a "half-window" 18 on one side of the subst.ratc substanti4:~lly in the region of the security device 20 which is applied io the first, lower sazface 11. of the st.rbstrate 10.
The substrate 10 of clear plastics matcxial preferably is formed from a transparent polymeric material which may be made, up of at least one bi-axially-oriented polymeric film. The substrate may comprise a single layer film of polymeric material. Alternatively, the substrate may comprise a laminate of two or more layers of transparent bi-axially-oriented polymeric film of the type described I~ in PCT Application WO 83100659 ~1_MPROVI~h BANKNO"1 ES AND THE LIKE).
The opacifying layers of ink 13, :l ~l, 15 anc~ 16 may comprise, any one or more of a variety of opaciaying inks which can be used in the printing of banknotes or other security cfocurnerrts. For c~;arrrple, the lay~;rs of c7paczfyng ink may comprise pigmented coat,ngs cc~rnprisirrg a loigrn~~~nt, such as titanium dioxide, dispersed within a binder or carrier of heat-actin°atcd cross-linkablce polymeric material as described in PCT t\pplication WO 1~3!OQb5~3 (IMPROVED BANKNOTES
AND THE LIKE).
The security device: ?0 may comprise one or more of a wide variety of security features. As shown in Figures ? and 3, the security device 20 is a printed 2~ feature comprising a repeating pattern of Iines 2~ printed onto the first, lower surface 11 of the substrate 10. Other types of printed featurta which can be used as security devices in the present invention include varying l~att~.rns. such as filigree patterns Of fine lines, micro-text, portraits or other images. 'I"he printed security feature may also be produced by including additives in the ink used to print the feature to create optical effects which can be used to enhance or add extra anti-counterfeiting security to the pattern or text. Thus, the inks used to print c.he security feature 20 could be coloured, fluorescent, phosphorescent, pearlescent or otherwise contain optically variable pigments or additives.
As shown in Figures 2 and 3, the printed security device 20 covers an area of the first, lower surface of the substrate 10 which extends transversely outside the area of the "half-window" 18 where there is no opacifying ink on the second surface 12 of the substrate 10. This can result in different optical effects as illustrated in Figures 2 and 3 when the security document is viewed from positions A and B
respectively (see Figure 1) on opposite sides of the document 1.
When the security device 20 is viewed from position A in reflected light, a central area 24 of the security device 20 is easily visible, but the outer area 26 of the security device 20 which extends beyond the area of the half-window 18 is either barely visible or not visible at all depending upon the opacity of the layers 15 and 16 of opacifying ink. When the security device is viewed from position B in reflected light, the whole of the security device 20 is barely visible or not visible at all depending upon the opacity of the layers 13 and 14 of opacifying ink.
Figure 2 shows the security device when viewed in transmitted light from position A. In this case, the whole of the security device 20 is visible, but there is a contrast between the outer area 26 of the security device 20 because different amounts of light are transmitted through the document 1 inside and outside the half-window area 18.
Figure 3 shows the security device 20 when viewed in transmitted light from position B. In this case, the whole of the security device 20 is also visible, but is not as readily visible as when viewed from position A because of the opacifying layers of ink 13 and 14 which cover the security device 20. However, because differing amounts of light are transmitted through the document inside and outside the half-window area 18, there is again a contrast between the relative visibilities of the central area 24 and the outer area 26 of the security device 20.
Referring to Figures 4 and 5, there is shown a security document 1 similar to the security document of Figure 1, and corresponding reference numerals have been applied to corresponding parts. The security device 30 of Figures 4 and 5 differs from that of Figures 2 and 3 in that it comprises a security stripe or thread applied to the first, lower surface 11 of the substrate 10 instead of the printed repeating pattern 20 of Figures 1 to 30. The security thread 30 may be formed from a metallic or plastics material which may be bonded to the first, lower surface 11 of the substrate 10. A metallic thread may be electrically conducting and/or magnetic.
S Alternatively, the security thread 30 may be printed onto the first, lower surface 1I
of the substrate 10. It may be optically variable, fluorescent, phosphorescent or pearlescent and it may contain micro-text.
As shown in Figure 5, the security thread 30 extends transversely outside the area of the half-window 18. Thus, when the security document 1 is viewed in transmitted light from position A, a central part 34 of the security thread 30 within the area of the half-window 18 is more readily visible than outer parts 36 of the security thread which extend outside the area of the half-window 18. A similar contrasting effect between the central part 34 and the outer parts 36 of the security thread 30 may be observed when the security document 1 is viewed in transmitted light from position B in Figure 4, but the central part 34 of the thread will not be as readily visible when viewed from position B in transmitted light than when viewed from position A.
In a further embodiment of the present invention, the security device 20 applied to the first, lower surface of the substrate 10 may be an optically variable device (OVD} such as a hologram or diffraction grating. The OVD may be either fully or partially metallised.
It will be appreciated that a security document in accordance with the present invention with the security device 20 or 30 applied to the first, lower surface of the substrate and subsequently covered by one or more layers of opacifying ink 13 and 14, is difficult to counterfeit, whilst being readily inspectable in the half-window area. Another advantage of the invention is that the security device 20 or 30 is protected by being buried between the clear plastics substrate 10 and the opacifying ink layer or layers 13, 14. It should be understood that in transmitted light such security devices may be observed, and exhibit excellent fidelity, even when buried under opacifying layers of ink. This observation is a function of the non-fibrous nature of the opacifying ink coatings and is a distinct advantage over paper based fibrous layers.
A preferred method of producing a security document in accordance with the invention comprises the following steps:
(a) providing the sheet-Iike substrate 10 of clear plastics material;
(b) applying the security device to the first, lower surface 11 of the substrate;
(c) printing one or more opacifying layers of ink 13, I4 on the first, Iower surface 11 of the substrate to cover the security device 20 or 30; and (d) printing one or more opacifying layers 15, 16 of ink onto the upper surface I2 of the plastic substrate except in the half-window area 18 above the security device 20 or 30.
In the embodiment of Figures 2 and 3 where the security device 20 is a printed feature, the security device may be applied to the Iower surface 11 of the clear plastics substrate 10 by using a gravure, offset or letter press printing process.
Where the security device is either a fully or partially metallised feature such as a metallic thread 30 or an OVD, the metallic thread or OVD may be transferred onto the first, lower surface 11 of the plastics substrate 10 by using a hot-stamping process in which the security device bonds to the lower surface 11 of the substrate 10. If the security thread 30 of Figures 4 and 5 comprises a printed feature, it may be printed onto the first, lower surface 11 of the clear plastics substrate 10 using a gravure or offset process.
Referring to Figure 6, there is shown another embodiment of the present invention which is similar to the embodiments of Figures 1 and 4, and corresponding reference numerals have been applied to corresponding parts. The embodiment of Figure 6 differs from Figures 1 and 4 in that it includes a front-to-back registration device comprising a first pattern 40 applied on the first, lower surface 11 of the clear plastics substrate 10 and a second pattern 50 applied on the second, upper surface 12 of the substrate 10.
The patterns 40 and 50 may comprise Moire patterns consisting of a series of lines 41, 51 having a predetermined spacing. When the security documents 1 is viewed in transmission from position A, and possibly also from position B, the combination of the two sets of lines 41 and 51 can product a Moire pattern due to interference effects. The security document of Figure 6 is very difficult to counterfeit because the nature of the Moire pattern produced by the security device 40, 50 depends upon the predetermined spacing between the lines 41 and 51 of the patterns 40 and 50 and also upon the width of the clear polymer substrate 10 separating the patterns 40 and 50.
In a preferred method of producing the security document of Figure 6, the series of lines 41 of pattern 40 may be printed onto the first, lower surface l I of the clear plastics substrate 10 by using a gravure or offset process; the series of lines 51 of the pattern 50 are printed onto the second, upper surface 12 of the clear plastics substrate 10 in register with the Lines 41 of pattern 40 preferably by using a gravure or offset printing process; and then one or more opacifying layers 13, 14; 15, 16 of ink can be printed onto the first and second surfaces 11 and I2 respectively of the clear plastics substrate 10 so that the layer or layers 13, 14 completely cover the pattern 40, with the layer or layers 15, 16 of ink being arranged to cover only a peripheral area 56 of the pattern 51 leaving a central area 54 of the pattern uncovered to form the half-window 18.
Another type of front-to-back registration device may include an area of metameric ink printed on the first lower surface of the substrate with a coloured layer applied to the second, upper surface of the substrate to form a coloured filter for viewing the area of metameric ink.
Further features of the half-window concept of the present invention which assist in preventing counterfeiting are that:
(i) the surface of the half-window is reflective in incident Light, and is thus easily distinguishable from the printed area of the note; and (ii) the tactility of the surface of the half-window is significantly different from the surrounding printed area.
It will be appreciated that various modifications may be made to the security documents and methods described above without departing from the scope and spirit of the present invention. For instance, the order in which the security devices 20;
30; 40, 50 and the opacifying layers of ink 13, 14, 15 and 16 are applied to the plastics substrate 10 may be varied, provided of course the security devices 20, 30 and 40 are applied to the first, lower surface of the substrate prior to application of the opacifying layers 13, 14 of ink.
This invention relates to security documents, such as banknotes or the like, and is particularly concerned with providing a security document formed from a plastic substrate with an enhanced secut°ity device..

It is therefore: desirable to provide a secu~~ity ~Ioci.uuc:nt which incorporates a security device that presents a different app~a~rantr~. fuon~ opposite sides of the;
document.
It is also desirable to provide a security d~~otin~mnt fortntTd from a ~le~:r plastics substrate with an enhanced forf~n of secuw;ity device.
It is further desirable to provide a relatively simple method of pravidin~; a security document with <~n enhanced farms of security cicvice.
a'ccordinp to at~c; aspect caf' the invcrltion, tho:re is hro,,~itied a security document comprising:
a sheet-like substrate of clear plastics material having first and second surfaces on apposite sues of the substrate;
said substrate having a region including a secctrity device;
at. least one layer of apac;ifying i.nk applied on a fiF~st sido of the substrate and at least partially obscuring said security device from one side of the substrate: and at least one layer of' apacifyino ink aLrplied an tire opposite side of the substrate in such a manner as to leave an area on said opposite side ~.~~hich is not ~i i covered by the opacifying ink substantially in the region including the security device.
According to another aspect of the invention, there is provided a method of producing a security document comprising the steps of:
providing a sheet-like substrate of clear plastics material having first and second surfaces on opposite sides of the substrate;
said substrate being provided with a security device in at least one region of the substrate;
applying at least one opacifying layer of ink on a first side of the substrate so as to obscure said security device from one side of the substrate; and applying at least one opacifying layer of ink to part of the opposite side of the substrate in such a manner as to leave an area which is not covered by ink substantially in the region of the security device.
Preferably, the layers of opacifying ink are applied directly to said first and 1S second surfaces of the substrate.
In the security document and method of the invention, the area of the second surface of the substrate which is not covered by the opacifying ink forms a "half-window" through which the security device may be inspected from one side of the substrate, the security device being at Ieast partly obscured by the opacifying ink when viewed from the opposite side of the substrate. Thus the security device has a different appearance when viewed from opposite sides of the document.
For instance, the security device may be clearly visible in the half-window from the side of the second surface of the substrate, but not visible or only partially visible, eg. only in transmission from the side of the first surface of the substrate.
Preferably, the security device is more visible in transmitted light than in reflected light from the side of the first surface of the substrate.
The security device may be formed within the transparent plastics substrate.
Alternatively, the security device may be applied to at least one of the first and second surfaces of the substrate.
In the method of the invention, the steps of applying the security device and of applying the layers of opacifying ink to the first and second surfaces of the substrate may be performed in different orders. For instance, the step of applying at least one layer of opacifying ink to part of the second surface of the substrate to form the half-window may be performed first before the steps of applying the security device to the substrate in the region of the half-window and of applying at least one opacifying layer to the first surface of the substrate to obscure the security device.
Preferably, however, the step of applying the security device to the substrate is performed prior to the steps of applying the layers of opacifying ink to the first and second surfaces of the substrate which may then be performed either simultaneously or one after another.
Preferably, part of the security device extends transversely outside the area of the "half-window" which is not covered by the opacifying ink on the second surface of the substrate. Preferably, the part of the security device which extends outside the area of the half-window is more visible in transmitted light than in reflected light. When a security device is provided in a banknote or security document in this manner, different parts of the security device may present different effects to a viewer from each side of the banknote or security document. For instance, if the layer or layers of opacifying ink only partially obscure the security device, the part of the security device outside the half-window area may be visible, at least in transmission, but not as apparent as the part of the security device within the area of the half-window. It is therefore possible for different contrasting effects to be observed between relative visibilities of the different parts of the substrate from both sides of the security document.
A wide variety of security devices may be employed in the present invention.
Examples of the type of security devices which may be applied to the substrate in the present invention include: fine line or filigree patterns; micro-text;
security stripes or threads; front and rear registration devices, including Moire patterns;
embossings; diffracting gratings; optically variable devices; coloured, fluorescent, phosphorescent and pearlescent inks and optically variable inks; metameric inks, and coloured filters which may be used to view such inks.
When the security device comprises a front to back registration device, such as a Moire pattern, different parts of the device may be applied to the first and second surfaces on both sides of the clear plastics substrate before the opacifying layers of ink are applied.
Alternatively, the security device may comprise a taggant provided within the substrate. The taggant may be invisible to the naked eye, but readable by a reading device through the half-window from the side of the second surface of the substrate.
In one embodiment of the invention, the security document may have a plurality of half-windows which are not covered by opacifying ink. The plurality of half-windows may be provided on both sides of the substrate. For instance, both the first and second surfaces of the substrate may have half-window areas at different transverse locations that are not covered by opacifying ink, said half-window areas being arranged alternately on the first and second surfaces of the substrate. A continuous security device, such as at least one security stripe or thread may extend through the half-window areas to give the appearance of a stripe or thread weaving through the substrate.
In order that the present invention may be more readily understood, various embodiments thereof will now be described, by way of example only, with reference to the accompanying drawings, in which:
Figure I is a sectional view through part of a security document in accordance with the invention;
Figure 2 is a view from one side of the security document of Figure 1;

Figure 5 is a view from one side of the security document of Figure 4; and Figure 6 is a sectional view through a security document in accordance with the invention incorporating a front-to-rear registration device.
In Figure 1, there is shown a security document 1 comprising a sheet-like substrate 10 of clear plastics material having a first, lower surface 11 and a second, upper surface 1?, layers 13 and 14 of opacifying ink applied on the first, lower WO 98/13211 PCT/AU97/0063?
surface 11 of the substrate 10, layers of opacifying ink 15 and 16 applied on the second, upper surface 12 of the substrate 10, and a security device ?G on the lower surface 11 of the substrat-~ 10 between the substrate 10 and the layer of opacifying ink 13.
As shown in Figure 1, the opacifying 1<zyers of irrk 1S and 16 arw not applied over the entire upper surface 12 of the substrate ~ () and thus leave an area of the second, upper surface 1.:.' which is not cowered l:zy opacifying ink to form a "half-window" 18 on one side of the subst.ratc substanti4:~lly in the region of the security device 20 which is applied io the first, lower sazface 11. of the st.rbstrate 10.
The substrate 10 of clear plastics matcxial preferably is formed from a transparent polymeric material which may be made, up of at least one bi-axially-oriented polymeric film. The substrate may comprise a single layer film of polymeric material. Alternatively, the substrate may comprise a laminate of two or more layers of transparent bi-axially-oriented polymeric film of the type described I~ in PCT Application WO 83100659 ~1_MPROVI~h BANKNO"1 ES AND THE LIKE).
The opacifying layers of ink 13, :l ~l, 15 anc~ 16 may comprise, any one or more of a variety of opaciaying inks which can be used in the printing of banknotes or other security cfocurnerrts. For c~;arrrple, the lay~;rs of c7paczfyng ink may comprise pigmented coat,ngs cc~rnprisirrg a loigrn~~~nt, such as titanium dioxide, dispersed within a binder or carrier of heat-actin°atcd cross-linkablce polymeric material as described in PCT t\pplication WO 1~3!OQb5~3 (IMPROVED BANKNOTES
AND THE LIKE).
The security device: ?0 may comprise one or more of a wide variety of security features. As shown in Figures ? and 3, the security device 20 is a printed 2~ feature comprising a repeating pattern of Iines 2~ printed onto the first, lower surface 11 of the substrate 10. Other types of printed featurta which can be used as security devices in the present invention include varying l~att~.rns. such as filigree patterns Of fine lines, micro-text, portraits or other images. 'I"he printed security feature may also be produced by including additives in the ink used to print the feature to create optical effects which can be used to enhance or add extra anti-counterfeiting security to the pattern or text. Thus, the inks used to print c.he security feature 20 could be coloured, fluorescent, phosphorescent, pearlescent or otherwise contain optically variable pigments or additives.
As shown in Figures 2 and 3, the printed security device 20 covers an area of the first, lower surface of the substrate 10 which extends transversely outside the area of the "half-window" 18 where there is no opacifying ink on the second surface 12 of the substrate 10. This can result in different optical effects as illustrated in Figures 2 and 3 when the security document is viewed from positions A and B
respectively (see Figure 1) on opposite sides of the document 1.
When the security device 20 is viewed from position A in reflected light, a central area 24 of the security device 20 is easily visible, but the outer area 26 of the security device 20 which extends beyond the area of the half-window 18 is either barely visible or not visible at all depending upon the opacity of the layers 15 and 16 of opacifying ink. When the security device is viewed from position B in reflected light, the whole of the security device 20 is barely visible or not visible at all depending upon the opacity of the layers 13 and 14 of opacifying ink.
Figure 2 shows the security device when viewed in transmitted light from position A. In this case, the whole of the security device 20 is visible, but there is a contrast between the outer area 26 of the security device 20 because different amounts of light are transmitted through the document 1 inside and outside the half-window area 18.
Figure 3 shows the security device 20 when viewed in transmitted light from position B. In this case, the whole of the security device 20 is also visible, but is not as readily visible as when viewed from position A because of the opacifying layers of ink 13 and 14 which cover the security device 20. However, because differing amounts of light are transmitted through the document inside and outside the half-window area 18, there is again a contrast between the relative visibilities of the central area 24 and the outer area 26 of the security device 20.
Referring to Figures 4 and 5, there is shown a security document 1 similar to the security document of Figure 1, and corresponding reference numerals have been applied to corresponding parts. The security device 30 of Figures 4 and 5 differs from that of Figures 2 and 3 in that it comprises a security stripe or thread applied to the first, lower surface 11 of the substrate 10 instead of the printed repeating pattern 20 of Figures 1 to 30. The security thread 30 may be formed from a metallic or plastics material which may be bonded to the first, lower surface 11 of the substrate 10. A metallic thread may be electrically conducting and/or magnetic.
S Alternatively, the security thread 30 may be printed onto the first, lower surface 1I
of the substrate 10. It may be optically variable, fluorescent, phosphorescent or pearlescent and it may contain micro-text.
As shown in Figure 5, the security thread 30 extends transversely outside the area of the half-window 18. Thus, when the security document 1 is viewed in transmitted light from position A, a central part 34 of the security thread 30 within the area of the half-window 18 is more readily visible than outer parts 36 of the security thread which extend outside the area of the half-window 18. A similar contrasting effect between the central part 34 and the outer parts 36 of the security thread 30 may be observed when the security document 1 is viewed in transmitted light from position B in Figure 4, but the central part 34 of the thread will not be as readily visible when viewed from position B in transmitted light than when viewed from position A.
In a further embodiment of the present invention, the security device 20 applied to the first, lower surface of the substrate 10 may be an optically variable device (OVD} such as a hologram or diffraction grating. The OVD may be either fully or partially metallised.
It will be appreciated that a security document in accordance with the present invention with the security device 20 or 30 applied to the first, lower surface of the substrate and subsequently covered by one or more layers of opacifying ink 13 and 14, is difficult to counterfeit, whilst being readily inspectable in the half-window area. Another advantage of the invention is that the security device 20 or 30 is protected by being buried between the clear plastics substrate 10 and the opacifying ink layer or layers 13, 14. It should be understood that in transmitted light such security devices may be observed, and exhibit excellent fidelity, even when buried under opacifying layers of ink. This observation is a function of the non-fibrous nature of the opacifying ink coatings and is a distinct advantage over paper based fibrous layers.
A preferred method of producing a security document in accordance with the invention comprises the following steps:
(a) providing the sheet-Iike substrate 10 of clear plastics material;
(b) applying the security device to the first, lower surface 11 of the substrate;
(c) printing one or more opacifying layers of ink 13, I4 on the first, Iower surface 11 of the substrate to cover the security device 20 or 30; and (d) printing one or more opacifying layers 15, 16 of ink onto the upper surface I2 of the plastic substrate except in the half-window area 18 above the security device 20 or 30.
In the embodiment of Figures 2 and 3 where the security device 20 is a printed feature, the security device may be applied to the Iower surface 11 of the clear plastics substrate 10 by using a gravure, offset or letter press printing process.
Where the security device is either a fully or partially metallised feature such as a metallic thread 30 or an OVD, the metallic thread or OVD may be transferred onto the first, lower surface 11 of the plastics substrate 10 by using a hot-stamping process in which the security device bonds to the lower surface 11 of the substrate 10. If the security thread 30 of Figures 4 and 5 comprises a printed feature, it may be printed onto the first, lower surface 11 of the clear plastics substrate 10 using a gravure or offset process.
Referring to Figure 6, there is shown another embodiment of the present invention which is similar to the embodiments of Figures 1 and 4, and corresponding reference numerals have been applied to corresponding parts. The embodiment of Figure 6 differs from Figures 1 and 4 in that it includes a front-to-back registration device comprising a first pattern 40 applied on the first, lower surface 11 of the clear plastics substrate 10 and a second pattern 50 applied on the second, upper surface 12 of the substrate 10.
The patterns 40 and 50 may comprise Moire patterns consisting of a series of lines 41, 51 having a predetermined spacing. When the security documents 1 is viewed in transmission from position A, and possibly also from position B, the combination of the two sets of lines 41 and 51 can product a Moire pattern due to interference effects. The security document of Figure 6 is very difficult to counterfeit because the nature of the Moire pattern produced by the security device 40, 50 depends upon the predetermined spacing between the lines 41 and 51 of the patterns 40 and 50 and also upon the width of the clear polymer substrate 10 separating the patterns 40 and 50.
In a preferred method of producing the security document of Figure 6, the series of lines 41 of pattern 40 may be printed onto the first, lower surface l I of the clear plastics substrate 10 by using a gravure or offset process; the series of lines 51 of the pattern 50 are printed onto the second, upper surface 12 of the clear plastics substrate 10 in register with the Lines 41 of pattern 40 preferably by using a gravure or offset printing process; and then one or more opacifying layers 13, 14; 15, 16 of ink can be printed onto the first and second surfaces 11 and I2 respectively of the clear plastics substrate 10 so that the layer or layers 13, 14 completely cover the pattern 40, with the layer or layers 15, 16 of ink being arranged to cover only a peripheral area 56 of the pattern 51 leaving a central area 54 of the pattern uncovered to form the half-window 18.
Another type of front-to-back registration device may include an area of metameric ink printed on the first lower surface of the substrate with a coloured layer applied to the second, upper surface of the substrate to form a coloured filter for viewing the area of metameric ink.
Further features of the half-window concept of the present invention which assist in preventing counterfeiting are that:
(i) the surface of the half-window is reflective in incident Light, and is thus easily distinguishable from the printed area of the note; and (ii) the tactility of the surface of the half-window is significantly different from the surrounding printed area.
It will be appreciated that various modifications may be made to the security documents and methods described above without departing from the scope and spirit of the present invention. For instance, the order in which the security devices 20;
30; 40, 50 and the opacifying layers of ink 13, 14, 15 and 16 are applied to the plastics substrate 10 may be varied, provided of course the security devices 20, 30 and 40 are applied to the first, lower surface of the substrate prior to application of the opacifying layers 13, 14 of ink.
