본 발명은 유가증권의 위조방지방법에 관한 것으로, 좀 더 상세하게는 유가증권이나 지폐 등의 은행권에 부착되는 보안요소의 접착도를 강화시키고 내구성을 향상시키며 위조 및 변조의 식별이 용이한 유가증권의 위조방지방법에 관한 것이다.The present invention relates to a method of preventing forgery of securities, and more particularly, to enhance adhesion of security elements attached to banknotes such as securities or banknotes, to improve durability, and to easily identify counterfeits and forgeries. The present invention relates to a method of preventing forgery.

통상적으로 은행을 비롯한 금융기관에서 발행하는 지폐나 유가증권(이하 통칭하여 '유가증권'이라고 칭한다)에는 컴퓨터 프린터나 스캐너, 컬러 복사기를 이용하여 위조 또는 변조하는 것을 방지하기 위한 보안수단이 구비되어 왔으며, 근래에는 상기한 복사기기들이 상당히 고성능화됨에 따라 더욱 새롭고 향상된 보안수단을 필요로 하고 있다.Generally, banknotes and securities issued by banks and other financial institutions (hereinafter referred to as 'securities') have been equipped with security measures to prevent forgery or tampering with computer printers, scanners, and color copiers. In recent years, as the above-mentioned copying machines become considerably high performance, new and improved security measures are needed.

현재 사용되고 있는 위조방지를 위한 보안수단으로는 기판에 특별한 패턴을 인쇄하는데 쓰이는 광가변잉크(OVI;optical variable device)나, 홀로그램(hologram) 형태의 광가변장치(OVD;optical variable devices)가 부착되어 왔으며, 이러한 보안 요소들은 전술한 복사기기에 의하여 복사하는 것이 불가능하지 않지만 매우 어려운 편이다.Security measures to prevent counterfeiting that are currently used include optical variable devices (OVI) for printing special patterns on substrates, or optical variable devices (OVD) in the form of holograms. These security elements are not impossible to copy by the copying machine described above but are very difficult.

다른 보안수단으로는 중첩된 선 및/또는 특수한 조건, 예를 들면 자외선(UV)이나 투명성에 의해서만 식별이 가능한 색을 가지는 패턴의 조합을 사용하고 있으며, 이러한 보안 수단의 장점은 그것들이 보호될 서류에 쉽게 인쇄 또는 배치될 수 있고 간단한 장치에 의해서 제어될 수 있으나, 그것들은 실제의 프린터, 스캐너, 또는 복사기에서 복제될 수는 없다는 것이다.Other security measures use combinations of overlapping lines and / or patterns with colors that can only be identified by special conditions, such as UV or transparency. Can be easily printed or placed on and controlled by a simple device, but they cannot be duplicated in an actual printer, scanner, or copier.

또 다른 보안수단으로는 종이류의 기판이 단지 투명한 상태에서만 보이는 선이나 패턴으로 표시되는 워터마크(watermark)를 사용한 것으로, 이보다 한 단계 더 높은 기술로서 불투명한 종이계 기판에 투명한 창을 형성하는 의사-워터마크(pseudo-watermarks)도 사용되고 있다.Another security measure is the use of watermarks, which are represented by lines or patterns seen only in the transparent state of the paper substrate, which is a further advanced technique for forming transparent windows on opaque paper-based substrates. Pseudo-watermarks are also used.

그러나, 종이계 기판에 투명창을 형성하는 것은 상당히 어려운 기술로서, 이에 PCT 출원 WO 99-14433에서는 투명한 중합체계 기판에 투명창으로 선택된 영역을 제외한 다른 영역을 인쇄하여 투명창을 형성하는 방식이 소개된바 있으나, 이 기술은 상기 투명창을 포함하는 영역에서 종이 기판이 국부적으로 약화되기 때문에 수명이 짧아 자주 교체되어야 하는 문제점이 있었다.However, it is a very difficult technique to form a transparent window on a paper-based substrate. Thus, PCT application WO 99-14433 introduces a method of forming a transparent window by printing an area other than a region selected as a transparent window on a transparent polymer substrate. However, this technique has a problem in that the paper substrate is locally weakened in the region including the transparent window, so that the life is short, so that it must be replaced frequently.

또 다른 방법으로 PCT 출원 WO 95-10420와 대한민국 특허 공개번호 제2005-44911호에서는 기판에 직접 구멍을 뚫어 투명창을 형성하고, 상기 투명창의 적어도 한쪽 면에 포일이나 박판 같은 투명한 스트립으로 구멍을 덮는 방식이 소개된 바 있다. 특히, 대한민국 특허 공개번호 제2005-44911호에서는 상기 투명창을 덮는 스크립에 전술한 바 있는 광가변장치(OVD)나 금속패치 등의 보안요소들을 적용한 실시예들을 다양하게 보여주고 있다. In another method, PCT application WO 95-10420 and Korean Patent Publication No. 2005-44911 form a transparent window by directly drilling a hole in a substrate, and covering the hole with a transparent strip such as foil or thin plate on at least one side of the transparent window. The method was introduced. In particular, Korean Patent Publication No. 2005-44911 shows various embodiments of applying security elements such as an optical variable device (OVD) or a metal patch to the script covering the transparent window.

그러나, 이와 같이 다양한 보안기술이 유가증권에 적용되었다 하더라도 위조 및 변조기술도 점점 고도화되기 때문에 더욱 향상되고 보강된 보안기술이 필요로 하며, 특히 보안요소의 접착도를 강화시키고 내구성을 향상시켜 위조 및 변조의 식별이 용이한 보안기술에 대한 연구는 지속적으로 이루어지고 있는 실정이다.However, even if such various security technologies are applied to securities, counterfeit and tampering techniques are increasingly advanced, and thus require more advanced and strengthened security technologies, and in particular, strengthen the adhesion of security elements and improve durability. Research on security technology that can easily identify tampering has been continuously conducted.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 유가증권에 부착되는 보안요소의 접착도를 강화시키고 내구성을 향상시키며 위조 및 변조의 식별이 용이한 유가증권의 위조방지방법을 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a method for preventing counterfeiting of securities that enhances the adhesion of the security element attached to the securities, improves durability, and facilitates identification of forgery and tampering. It is done.

상기와 같은 목적을 달성하기 위하여 본 발명은 The present invention to achieve the above object

기판의 소정 부위를 천공하여 투명창을 형성하고, 상기 기판의 투명창을 사이에 두고 미세통공이 형성된 광가변장치(OVD)와, 투명도를 갖는 보호 필름을 천공을 커버하도록 위치시킨 다음 동시에 압착하여 리벳트(Rivet) 방식으로 부착하는 것을 특징으로 하는 유가증권의 위조방지방법을 제공함으로써 달성된다.A transparent window is formed by drilling a predetermined portion of the substrate, and the optical variable device (OVD) having micropores formed therebetween the transparent window of the substrate and a protective film having transparency are positioned to cover the perforations, and then simultaneously compressed. It is achieved by providing a method of preventing forgery of securities, which is attached in a riveting manner.

이하에서는 본 발명에 대하여 첨부된 도면에 도시된 실시예에 따라 구체적으로 설명하기는 하나, 본 발명이 도면에 도시된 실시예만으로 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited to the embodiments shown in the drawings.

도 1은 본 발명의 유가증권을 나타낸 분해 사시도이고, 도 2는 본 발명의 유가증권을 나타낸 결합 사시도이다.1 is an exploded perspective view showing the security of the present invention, Figure 2 is a combined perspective view showing the security of the present invention.

이에 도시된 바와 같이 본 발명은 기판(10)의 소정 부위를 천공하여 투명창(11)을 형성하고, 상기 기판(10)의 투명창(11) 상. 하면에 미세통공(21)이 형성된 광가변장치(이하 'OVD'라 칭함)(20)와, 투명도를 갖는 보호필름(30)을 동시에 압착하는 방법에 의해 제조된다.As shown in the present invention, the transparent window 11 is formed by drilling a predetermined portion of the substrate 10, and on the transparent window 11 of the substrate 10. The optical variable device (hereinafter referred to as 'OVD') 20 having the micro-pores 21 formed on the lower surface thereof, and the protective film 30 having transparency are simultaneously manufactured by pressing.

먼저, 본 발명에 사용되는 기판(10)은 현재 통용되고 있는 유가증권을 비롯하여 지폐, 상품권 등에 사용되는 종이기판이 주요대상이 되나, 이에 한정되는 것은 아니며 카드, 신분증, 여권 등에 사용되는 합성수지 기판도 그 대상이 된다.First, the substrate 10 used in the present invention is a paper substrate used for banknotes, gift certificates, etc., including currently used securities, the main target, but is not limited thereto, synthetic resin substrates used for cards, ID cards, passports, etc. It is the object.

이러한 기판(10)의 소정 부위, 즉 보안요소를 부착하기 위한 부위,에 펀칭을 통해 천공된 투명창(11)을 형성하며, 이러한 투명창(11)은 도면에 도시된 바와 같은 원형 뿐만 그 외 다양한 모양도 가능하다.A punched transparent window 11 is formed on a predetermined portion of the substrate 10, that is, a portion for attaching a security element, through punching, and the transparent window 11 is circular as shown in the drawing. Various shapes are also available.

이와 같이 기판(10)에 천공된 투명창(11)을 형성한 다음, 상기 투명창(11)을 사이에 두고 그 상·하면에 미세통공(21)이 형성된 OVD(20)와, 투명도를 갖는 보호필름(30)을 위치시킨다. 상기 OVD(20)와 보호필름(30)의 위치는 바뀌어도 무방하다After forming the transparent window 11 perforated on the substrate 10 as described above, the OVD 20 having the micro-holes 21 formed on the upper and lower surfaces with the transparent window 11 therebetween, and having transparency Place the protective film 30. The positions of the OVD 20 and the protective film 30 may be changed.

상기와 같이 사용되는 OVD(20)는 보는 각도에 따라 색깔이나 모양이 변하는 광가변장치로서 지폐 제조분야에서 보안요소로 널리 사용되고 있는 것이다. 다만, 본 발명에 사용되는 OVD(20)에는 레이저를 이용하여 육안으로는 확인하기 어려운 다수개의 미세통공(21)이 형성되어 있는 것을 특징으로 하고 있다. The OVD 20 used as described above is an optical variable device whose color or shape changes depending on the viewing angle, and is widely used as a security element in the banknote manufacturing field. However, the OVD 20 used in the present invention is characterized in that a plurality of micro-perforations 21 are hardly visible with the naked eye using a laser.

한편, 이와 같은 미세통공(21)을 도 1에서와 같이 무분별하게 형성하는 것이 아니라, 도 2에 보여주는 바와 같이 미세통공(21)을 형성함에 있어 글자나 문양, 바코드 등을 나타내도록 특수패턴화된 미세형공(21a)을 형성하여 고성능의 복사기에서는 위조가 되지 않는 보안특성을 추가할 수 있다.On the other hand, rather than indiscriminately forming such a micro-hole 21 as shown in Figure 1, in the formation of the micro-hole 21 as shown in Figure 2 is a special patterned to represent letters, patterns, barcodes, etc. By forming the fine hole 21a, it is possible to add a security characteristic that is not forged in a high-performance copier.

상기한 OVD(20)와 함께 사용되는 보호필름(30)은 대표적으로 폴리에틸렌(PE),폴리에스테르(PET),폴리카보네이트(PC) 필름이 사용되나 이에 한정되는 것 은 아니며, 그 외에도 잘 알려진 투명필름들이 사용될 수 있다. 또한, 보호필름(30)은 완전히 투명한 필름 뿐만 아니라 빛이 투과되는 한도 내에서 반투명 또는 불투명처리한 것도 사용이 가능하다. The protective film 30 used together with the OVD 20 is typically a polyethylene (PE), polyester (PET), polycarbonate (PC) film is used, but is not limited to this, in addition to the well-known transparent Films can be used. In addition, the protective film 30 may be used not only a completely transparent film but also semi-transparent or opaque treatment within the extent to which light is transmitted.

아울러, 상기한 보호필름(30)에도 역시 보안특성을 강화하기 위하여 무색형광잉크, 광가변잉크와 같은 특수잉크로 글자나 문양, 바코드 형태로 인쇄된 인쇄영역(31)을 형성할 수 있다.In addition, the protection film 30 may also form a printed area 31 printed in a special ink, pattern, or bar code in a special ink such as a colorless fluorescent ink or a variable ink to enhance security characteristics.

상기와 같이 기판(10)의 투명창(11)을 사이에 두고 OVD(20)와 보호필름(30)을 위치시킨 상태에서 동시에 압착하여 기판(10)에 부착시키게 되는데, 이에 대하여 하기 도 3과 도 4를 통하여 좀 더 상세하게 설명하기로 한다.As described above, the OVD 20 and the protective film 30 are positioned at the same time with the transparent window 11 of the substrate 10 interposed therebetween, and are attached to the substrate 10 at the same time. This will be described in more detail with reference to FIG. 4.

도 3은 본 발명의 주요부분을 확대하여 나타낸 분해 단면도이고, 도 4는 본 발명의 보안요소가 결합된 상태를 나타낸 단면도이다.3 is an exploded cross-sectional view showing an enlarged main part of the present invention, Figure 4 is a cross-sectional view showing a state in which the security element of the present invention is coupled.

이에 도시된 바와 같이, 상기와 같이 기판(10)의 투명창(11)을 사이에 두고 OVD(20)와 보호필름(30)을 섭씨 130도, 0.5Bar의 가압롤러에 의해 압착하여 OVD(20)와 보호필름(30)이 기판(10)에 리벳트(Rivet) 방식으로 부착되도록 한다. As shown in the drawing, the OVD 20 and the protective film 30 are pressed by a pressure roller of 130 degrees Celsius and 0.5 Bar with the transparent window 11 of the substrate 10 therebetween as described above. ) And the protective film 30 to be attached to the substrate 10 in a riveting (Rivet) method.

상기와 같이 OVD(20)와 보호필름(30)이 압착되어 투명창(11) 내에서 서로 밀착하는 과정에서 보호필름(30)은 OVD(20)의 미세통공(20) 내로 밀려들어가 충진된 상태로 결합됨에 따라 또 다른 리벳트(Rivet) 결합이 이루어진다. As described above, the OVD 20 and the protective film 30 are compressed to be in close contact with each other in the transparent window 11, and the protective film 30 is pushed into the micro-hole 20 of the OVD 20 to be filled. Combining with another rivet (Rivet) is made.

따라서, OVD(20)과 보호필름(30)은 일차적으로 기판(10)의 투명창(11)을 통해 1차적으로 리벳트(Rivet) 결합이 이루어지고, OVD(20)과 보호필름(30) 사이에는 미세통공(21)을 통해 2차적인 리벳트(Rivet) 결합이 이루어져, 종래보다 보안요소 와 기판의 결합력을 향상시킴에 따라 지면접착도가 월등하고 내구성이 높아지게 된다.Therefore, the OVD 20 and the protective film 30 are primarily riveted through the transparent window 11 of the substrate 10, and the OVD 20 and the protective film 30 are primarily formed. Secondary rivets (Rivet) coupling is made through the micro-holes 21 therebetween, as the adhesion between the security element and the substrate is improved than before, the surface adhesion is superior and durability is increased.

한편, 이와 같이 기판(10)의 투명창(11)을 사이에 두고 OVD(20)와 보호필름(30)을 부착함으로써 얻어지는 보안효과는 종래기술에서 소개된 대한민국 특허 공개번호 제2005-44911호에서 언급된 바 있으나, 특히 본 발명에서는 OVD(20)에는 미세통공(21)이 형성되고 보호필름(30)은 불투명한 인쇄영역(31)을 가짐에 따라 이러한 보안요소에 대한 빛의 투과와 간섭, 반사가 더욱 복잡하게 이루어지도록 하여 OVD(20)와 보호필름(30)을 통해 보여지는 문양의 변화를 더욱 다양하게 할 수 있으며, 따라서 스캐너나 복사기로는 재현이 거의 불가능한 보안효과를 가져온다. Meanwhile, the security effect obtained by attaching the OVD 20 and the protective film 30 with the transparent window 11 of the substrate 10 interposed therebetween is disclosed in Korean Patent Publication No. 2005-44911 introduced in the prior art. As mentioned, in particular, in the present invention, as the micro-hole 21 is formed in the OVD 20 and the protective film 30 has an opaque printing area 31, the transmission and interference of light to such a security element, By making the reflection more complicated, it is possible to more variously change the pattern shown through the OVD 20 and the protective film 30, thus bringing a security effect that is almost impossible to reproduce with a scanner or copier.

아울러, 상기와 같은 부착과정에서 OVD(20)에 형성된 문양과 보호필름(30)에 추가적인 보안요소로 사용된 인쇄영역(31)의 문양을 동일하게 형성하여 앞뒤맞춤식으로 부착하면 더욱 바람직한 효과를 가져올 수 있다. In addition, the same pattern of the print area 31 used as an additional security element in the pattern formed on the OVD 20 and the protective film 30 in the attachment process as described above to bring about a more desirable effect if the front and back to attach. Can be.

이러한 앞뒤맞춤식은 동일한 문양이 형성된 인쇄판을 앞뒤로 설치하고 OVD(20)과 보호필름(30)에 동시에 인쇄함으로써 이루어지는 방법으로, 이 경우 빛을 투과하여 살펴보면 OVD(20)과 보호필름(30)에 문양이 서로 일치하여 완전한 문양이 이뤄짐으로써 위조 및 변조가 어렵고 식별은 용이해지도록 한다.This front and rear alignment is formed by printing the front and back of the same pattern is formed on the front and back of the OVD 20 and the protective film 30 at the same time, in this case through the light to see the pattern on the OVD 20 and the protective film 30 The matching of these patterns makes them difficult to forge and tamper with, making identification easier.

이와 같이 위조방지방법에 의해 보안수단이 구비된 유가증권은 기판의 투명창에 서로 다른 보안요소를 부착함으로써 인쇄된 투명 보안필름을 통해 비치는 OVD의 위조방지효과와 OVD 상의 천공부위를 통해 비춰지는 보안필름의 문양을 함께 활용할 수 있어 종래보다 고도화된 보안수단을 겸비할 수 있을 뿐만 아니라 이러한 보안요소의 기판에 대한 결합력을 향상시킴에 따라 지면접착도가 월등하고 내구성이 높아지게 된다.Securities equipped with security measures by the anti-counterfeiting method as described above attach different security elements to the transparent window of the substrate, thereby preventing the anti-counterfeiting effect of the OVD reflected through the printed transparent security film and the security reflected through the perforations on the OVD. The use of the pattern of the film can be used together to combine the security means more advanced than the conventional as well as improve the bonding strength of the security element to the substrate, the surface adhesion is superior and durability is increased.

아울러. 본 발명은 전술한 바와 같이 금융 및 비금융 분야에서 통용되는 유가증권을 비롯하여 지폐나 수표와 같은 은행권 뿐만 아니라 카드, 신분증, 여권, 상품권 등에도 적용하여 사용할 수 있음을 밝혀둔다.together. As described above, the present invention can be applied to not only banknotes such as banknotes and checks, but also cards, ID cards, passports, gift certificates, etc., which are commonly used in the financial and non-financial fields.

상술한 바와 같이 본 발명의 유가증권의 위조방지방법은 기판의 투명창에 서로 다른 보안요소를 부착함으로써 인쇄된 투명 보안필름을 통해 비치는 OVD의 위조방지효과와 OVD 상의 천공부위를 통해 비춰지는 보안필름의 문양을 함께 활용할 수 있어 종래보다 고도화된 보안수단을 겸비할 수 있을 뿐만 아니라 이러한 보안요소의 기판에 대한 결합력을 향상시킴에 따라 지면접착도가 월등하고 내구성이 높아지는 효과를 가져온다.As described above, the anti-counterfeiting method of the securities of the present invention has the anti-counterfeiting effect of the OVD reflected through the transparent security film printed by attaching different security elements to the transparent window of the substrate, and the security film reflected through the perforated portion on the OVD. It can be used together with the pattern of the more advanced security means than the conventional as well as improve the bonding strength of the board of the security element, resulting in the effect of superior ground adhesion and durability.
