Description

보안문서 및 그 제작방법{Security document and method thereof}Security document and its manufacturing method

본 발명은 보안문서 및 그 제작방법에 관한 것으로, 보다 상세하게는 오랫동안 사용하더라도 위변조여부의 식별이 가능하여 보안이 효과적으로 이루어짐은 물론 제작비도 절감할 수 있는 보안문서 및 그 제작방법에 관한 것이다. The present invention relates to a security document and a manufacturing method thereof, and more particularly, to a security document and a method of manufacturing the same, which can identify forgery and alteration even if it is used for a long time, thereby making security effective and reducing production costs.

지금까지 여권, 지폐, 수표, 유가증권, 채권 또는 기밀 전용 문서를 위조나 변조하는 경우가 많이 있어왔다. 이에 따라, 그 위변조여부를 식별할 수 있는 기술들 또한 많이 개발되고 있다. To date, there have been many cases of forgery or alteration of passports, bills, checks, securities, bonds or confidential documents. Accordingly, many techniques for identifying whether the forgery is being developed are also developed.

이러한 위변조방지 기술들 중에서, 자외선램프에서 발광하는 형광잉크와 발광하지 않는 무형광의 용지를 이용하는 기술이 있다. 예를 들면, 지폐나 문서 등의 용지로 무형광재질을 사용하고, 이 용지에 형광잉크를 사용하여 특수문자나 도형, 그림 등을 입힘으로써, 일반광에서는 보이지 않던 상기의 형상이 자외선이 조사되면 나타나게되어 위조여부를 판별할 수 있는 기술이다. 하지만, 형광잉크는 일반광에서 일정시간이 경과하면 증발되거나 훼손되어 그 기능이 떨어지므로, 오랜시간이 경과된 후에는 자외선을 조사하더라도 상기의 그림 등이 나타나지 않게 되어 위변조여부를 판별할 수 없게 된다. 한편, 상기한 무형광의 용지는 형광증백제를 사용하지 않은 친환경소재인 특수용지로써 고가이기 때문에 비용이 많이 드는 문제가 있다. Among these forgery and alteration prevention techniques, there is a technique using a fluorescent ink emitting light from an ultraviolet lamp and a non-fluorescent paper that does not emit light. For example, intangible materials are used for papers such as banknotes and documents, and special characters, figures, drawings, etc. are applied to the papers using fluorescent ink so that the above-mentioned shapes, which were not seen in ordinary light, appear when ultraviolet rays are irradiated. It is a technology that can determine whether the forgery. However, since a fluorescent ink is evaporated or damaged after a certain time elapses from normal light, its function is deteriorated. Therefore, even after irradiation with ultraviolet light, the above picture does not appear, and thus it is impossible to determine whether or not forgery. . On the other hand, the non-fluorescent paper is expensive because it is expensive as a special paper which is an eco-friendly material that does not use a fluorescent brightener.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 내구성을 증대시켜서 장시간 노출되더라도 위변조여부를 식별할 수 있어 보안이 효과적으로 이루어짐은 물론 제작비도 절감할 수 있는 보안문서 및 그 제작방법을 제공하는 것이다. The present invention is to solve the problems as described above, the object of the present invention is to increase the durability, even if exposed for a long time can be identified whether the forgery security is made effective, as well as a security document that can reduce the production cost and its production To provide a way.

본 발명의 특징에 따르면, 형광물질이 처리된 형광용지(1)와, 이 형광용지(1)에 무형광잉크가 도포된 인쇄부(3)를 포함하며, 상기 형광용지(1)이 자외선이 조사되면 상기 인쇄부(3) 이외의 부분이 발광하는 것을 특징으로 하는 보안문서가 제공된다. According to a feature of the invention, it comprises a fluorescent paper (1) treated with a fluorescent material, and a printing portion (3) coated with a fluorescent ink (1), the fluorescent paper (1) is irradiated with ultraviolet light When a portion other than the printing unit 3 is provided, the security document is characterized in that the light.

본 발명의 다른 특징에 따르면, 형광물질이 처리된 형광용지(1)를 준비하는 단계와, 상기 형광용지(1)에 디자인된 형상대로 무형광잉크를 도포하는 단계를 포하며, 자외선이 조사되면 상기 무형광잉크가 도포된 부분 이외의 부분이 발광하는 것을 특징으로 하는 보안문서의 제작방법이 제공된다. According to another feature of the present invention, comprising the steps of preparing a fluorescent paper (1) treated with a fluorescent material, and applying a non-fluorescent ink in the shape designed on the fluorescent paper (1), when the ultraviolet light is irradiated There is provided a method for producing a security document, characterized in that light is emitted from portions other than the portion to which the fluorescence-free ink is applied.

이상에서와 같이 본 발명에 의하면, 비교적 저렴하여 구입이 용이한 형광용 지(1)에 디자인된대로 무형광잉크를 도포함으로써, 자외선이 조사되면 무형광잉크가 도포된 부분 이외의 부분이 외부로 나타나게 되므로, 기존에 고가의 무형광용지를 사용하던 것에 비해 비용을 절감할 수 있을 뿐만 아니라 기존 형광잉크의 발광수명이 한정되어 있어서 일정시간 경과후에는 위변조 여부의 식별이 어렵던 것에서 벗어나서 오랜시간이 경과된 후에도 위변조여부의 식별이 가능한 효과가 있다. As described above, according to the present invention, by applying the fluorescent inks as designed on the fluorescent paper 1, which is relatively inexpensive and easy to purchase, when ultraviolet rays are irradiated, portions other than the portions where the fluorescent inks are applied appear to the outside. In addition, it is possible to reduce the cost compared to the conventional use of expensive intangible fluorescence paper, and the emission life of the existing fluorescent ink is limited, so it is difficult to identify whether or not forgery after a certain time and forgery even after a long time has elapsed. It is possible to identify whether or not.

상술한 본 발명의 목적, 특징들 및 장점은 다음의 상세한 설명을 통하여 보다 분명해질 것이다. 이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.The objects, features and advantages of the present invention described above will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 일실시예에 따른 평면도를 도시한 것이다. (a)는 일반광에 노출시킨 본 발명에 따른 보안문서이고, (b)는 자외선램프에 노출시킨 본 발명에 따른 보안문서이다. 이때, 도 1의 (a)에서 점선으로 나타낸 글자는 실제로는 육안으로는 볼 수 없는 것이다. Figure 1 shows a plan view according to a preferred embodiment of the present invention. (a) is a security document according to the present invention exposed to normal light, (b) is a security document according to the present invention exposed to an ultraviolet lamp. In this case, the letters indicated by dotted lines in FIG. 1A are not actually visible to the naked eye.

도 1에 도시된 바와 같이, 본 발명에 따른 보안문서는 형광용지(1)와, 이 형광용지(1)에 무형광잉크가 일정 형태로 도포된 인쇄부(3)를 포함하여 구성되며, 자외선이조사되는 경우에만 상기 인쇄부(3) 이외의 부분이 발광하여 외부로 드러나는 것이다.As shown in FIG. 1, the security document according to the present invention includes a fluorescent paper 1 and a printing part 3 coated on the fluorescent paper 1 with a non-fluorescent ink in a predetermined form. Only when irradiated, parts other than the printing unit 3 emit light and are exposed to the outside.

상기 형광용지(1)는 형광증백제 등을 이용하여 형광처리된 용지로써, 대체로 형광증백제는 본래 색상의 용지를 백색으로 처리하기 위해 사용되는 것이다. 따라 서, 이러한 형광용지(1)는 대부분 백색이며 우리가 흔히 사용하는 A4용지 등이 이에 해당한다. 따라서, 본 발명에 사용되는 형광용지(1)는 일반적으로 가격이 저렴하여 구입이 용이하다. 이러한 형광용지(1)에 자외선을 조사하게 되면, 형광물질이 발광하게 되어 일반광에서와는 다른 색상을 나타내게 되는데, 대체로 파란색을 나타내게 된다.The fluorescent paper 1 is a paper that has been fluorescently treated with a fluorescent brightener or the like, and is generally used to treat a paper of an original color as white. Therefore, the fluorescent paper 1 is mostly white, and A4 paper and the like that we commonly use corresponds to this. Therefore, the fluorescent paper 1 used in the present invention is generally cheap and easy to purchase. When the ultraviolet light is irradiated on the fluorescent paper 1, the fluorescent material emits light, which is different from general light, and is generally blue.

상기 인쇄부(3)는 형광용지(1)에 일정한 형태로 무형광잉크가 도포된 부분이며, 즉, 형광용지(1)에 문자, 숫자, 기호, 도형 또는 그림(2)을 스케치하고 그 이외의 부분에 무형광잉크를 도포함으로써, 이 도포된 부분이 인쇄부(3)를 형성한다.The printing unit 3 is a portion in which fluorescent-free ink is applied to the fluorescent paper 1 in a predetermined form, that is, letters, numbers, symbols, figures or drawings (2) are sketched on the fluorescent paper 1 and other than that. By applying the non-fluorescent ink to the portion, this coated portion forms the printing portion 3.

도 1에서는 '보안'이라는 문자(2) 이외의 부분에 무형광잉크가 도포된 것으로, 이 부분이 인쇄부(3)가 된다. 이때, 상기 무형광잉크는 상기 자외선을 조사하더라도 자연광에서와 동일한 색상을 나타내는 잉크이다. 즉, 자연광에서 형광용지(1)가 나타나는 색상과 동일한 색상을 갖는 잉크다. 따라서, 형광용지(1)의 일면 전체에 무형광잉크를 도포하면, 자외선을 조사하더라도 형광용지(1)는 일반광에서의 색상과 동일한 색상을 나타낸다. In Fig. 1, the non-fluorescent ink is applied to a portion other than the letter 2 of 'security', and this portion becomes the printing portion 3. In this case, the non-fluorescent ink is ink that shows the same color as in natural light even when the ultraviolet light is irradiated. That is, the ink has the same color as that of the fluorescent paper 1 in natural light. Therefore, when the non-fluorescent ink is applied to the entire surface of the fluorescent paper 1, the fluorescent paper 1 exhibits the same color as that of normal light even when irradiated with ultraviolet rays.

이와 같이 구성된 본 발명 보안문서를 제작하는 방법을 설명하면 다음과 같다. 형광용지(1)에 자외선이 조사되면 '보안'이라는 문자(2)가 나타나도록 하는 방법을 설명하기로 한다. Referring to the method of producing a security document of the present invention configured as described above are as follows. When ultraviolet light is irradiated on the fluorescent paper 1, a method of displaying the letter '2' will be described.

우선, 준비된 형광용지(1)의 일면에 '보안'이라는 문자(2)를 스케치하고, 이 '보안'이라는 문자(2)를 제외한 나머지 부분 즉, 인쇄부(3)에 무형광잉크를 도포한다. 이때, 스케치도 형광용지(1)와 동일한 색상의 필기구나 기타 특수장비를 사용 하여, 일반광에서 스케치의 흔적이 남지 않도록 한다. 그리고, 형광등과 같은 일반광에서 무형광잉크가 형광용지(1)와 동일한 백색을 나타내므로, 자외선이 조사되는 공간에서 무형광잉크를 도포하는 작업이 보다 손쉬울 것이다. 이와 같이 완성된 보안문서는 일반광에서는 일반 A4용지와 동일하게 어떠한 표시도 없는 백색의 용지로 나타난다. 하지만, 이 보안문서에 자외선을 조사하게 되면, 상기 인쇄부(3)를 제외한 부분이 일반광에서와 다른 색상인 파란색을 나타내게 되는데, 도 1(b)에서와 같이 '보안(2)'이라는 문자가 나타나게 된다. First, the letter "2" is sketched on one surface of the prepared fluorescent paper 1, and the fluorescence ink is applied to the remaining portion except for the letter "2", that is, the printing unit 3. At this time, the sketch also uses writing instruments or other special equipment of the same color as the fluorescent paper (1), so that the trace of the sketch does not remain in the normal light. In addition, since the non-fluorescent ink exhibits the same white color as the fluorescent paper 1 in ordinary light such as a fluorescent lamp, it will be easier to apply the non-fluorescent ink in a space to which ultraviolet rays are irradiated. The security document thus completed appears as white paper without any marking in the same way as ordinary A4 paper in ordinary light. However, when the ultraviolet light is irradiated to the security document, the portion except for the printing unit 3 has a blue color which is different from that of general light, and as shown in FIG. Will appear.

도 2는 본 발명에 따라 제작된 보안문서를 일반광과 자외선광에 각각 노출시킨 것을 찍은 사진이다. 즉, 상기한 설명에 비추어 도 2를 참조하면, 왼쪽사진처럼 일반광에서는 어떠한 표시도 나타나지 않지만, 오른쪽사진처럼 자외선을 조사하게 되면 무형광잉크가 도포된 인쇄부(3)를 제외한 그 이외의 부분이 나타나게 된다. 사진에서는 특정문자가 파란색으로 나타나는 것을 볼 수 있다.Figure 2 is a photograph taken to expose the security document produced in accordance with the present invention to normal light and ultraviolet light, respectively. That is, referring to FIG. 2 in the light of the above description, no indication is shown in general light as in the left picture, but when the ultraviolet light is irradiated as in the right picture, other parts except for the printing part 3 to which the afluorescent ink is applied are Will appear. In the picture, you can see that certain characters appear in blue.

한편, 상기 실시예에서는 '보안'이라는 문자 이외의 부분에 무형광잉크가 도포되어 이 부분이 인쇄부가 된 것을 예시하였으나, 경우에 따라서는 보안이라는 문자 부분에 무형광잉크를 도포함으로써 보안이라는 문자가 인쇄부가 될 수 있다. 이 경우에, 자외선이 조사되면 보안이라는 문자 이외의 여백부위가 파란색으로 나타나게 되어, 역시 보안이라는 문자가 나타나게 된다.On the other hand, in the above embodiment, the non-fluorescent ink is applied to the portion other than the word 'security' to illustrate that the portion is a printing portion, in some cases, by applying the non-fluorescent ink to the portion of the security characters, the security character is printed Can be. In this case, when the ultraviolet rays are irradiated, margin areas other than the security text appear in blue, and the security text also appears.

이와 같이 만들어진 문서가 위변조되었는지 여부를 검사하는 경우, 그 문서에 자외선을 조사하더라도 어떠한 표시도 나타나지 않게 되면 그 문서는 위변조된 것이다. 이러한 형광용지(1)는 일반적으로 구입할 수 있는 용지로서 고가의 무형광 용지에 비해 가격이 상당히 저렴하고, 무형광용지의 일면에 단순히 도포된 형광잉크에 비해 형광물질이 특수처리된 형광용지(1)가 형광물질이 발광하는 성질이 오래지속되므로 오랜시간이 지나도 그 문서의 위변조여부를 식별할 수 있다. In the case of checking whether the document thus produced has been forged, the document is forged if the document is irradiated with ultraviolet rays and no indication is displayed. The fluorescent paper 1 is generally a commercially available paper, which is considerably cheaper than the expensive non-fluorescent paper, and the fluorescent paper 1 that has been treated with a fluorescent material specially compared to the fluorescent ink simply coated on one surface of the non-fluorescent paper Fluorescent materials emit light for a long time, so that the document can be forged after a long time.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 명백할 것이다.The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
