본 발명은 위조를 방지할 수 있는 종이에 관한 것으로, 최근 정보화 시대에 들어오면서 사무자동화기기 발달과 함께 천연색 복사의 재현력이 우수한 CLC-500(Color laser copier) Digital 천연색 복사기의 등장으로 인하여 은행권, 유가증권, 기밀을 요하는 문서, 신분증 및 출입증을 쉽게 복사 위조할 수 있게 됨에 따라 원고를 복사기에서 어느 방향으로 복사하여도 잠상이 돌출되게 하여 진품과 복사품으로 육안으로 쉽게 식별할 수 있게 하는 잠삼현출에 의한 위조방지용지에 관한 것이다.The present invention relates to a paper that can prevent forgery, banknotes, oil prices due to the emergence of the CLC-500 (Color laser copier) Digital color copier with excellent color reproduction with the development of office automation equipment in the recent information age. As it becomes easy to copy and forge securities, confidential documents, ID cards, and passes, the latent image can be protruded in any direction from the copier, making it easy to visually identify the originals and copies. It relates to a forgery prevention paper.

종래에는 금속분말(金粉 : 동합금분말, 은분(銀粉) : 알루미늄분말), 형광 잉크와 같은 특수잉크를 사용하여 천연색 복사기 토너가 재현할 수 없는 색상으로 인쇄함으로서 천연색 복사시 색상이 재현되지 않고 소실되게 하여 복사방지 효과를 나타내는 위조방지방법이 실시된 바 있으나, 이와 같이 특수 잉크를 사용한 인쇄 방법은 은행권, 유가증권 또는 중요 문서로서의 품위를 손상케 하고, 복사 위조방지효과가 미흡할 뿐만 아니라, 시중에서의 특수잉크 구입용기에 따른 위조가능성이 있어 그 실효가 적었다. 그리고 인쇄패턴방식으로서 위조방지의 필요가 있는 용지에 "복사" 등과 같은 잠상문자와 잠상 이외의 배경을 형성시키되 잠상과 배경을 큰 망점(dot)과 작은 망점으로 구분하여 인쇄형성시키므로서 양자간의 농담 차이를 이용하여 큰 망점은 복사시 재현되나 작은 망점은 소실되게 하는 기술이라던가 또는 잠상문자와 배경을 선(線 : solid line)과 망점으로 형성시키는 기술이 개발된 바 있으나 이와같은 기술은 이를 실시하기 위하여 인쇄판 제작용 필름을 제작할 때에 잠상문자와 배경과의 농담차이가 아주 적더라도 잠상의 육안 식별이 용이하게 되며, 또한 필름제작시 인쇄판재(PS판, 나이로판)에 따라 일일이 농담을 조정하여야 하는 결점이 있다.Conventionally, by using a special ink such as metal powder (金 粉: copper alloy powder, silver powder: aluminum powder), fluorescent ink, the color copier toner is printed in a color that cannot be reproduced, so that color is not reproduced and disappeared when copying natural colors. The anti-counterfeiting method, which shows the effect of copy protection, has been implemented.However, the printing method using the special ink not only impairs the quality of banknotes, securities, or important documents, but does not have sufficient copy-counterfeiting effect. There was a possibility of counterfeiting according to the special ink purchase container of the product. As a printing pattern method, a background other than latent images and latent images such as "copy" is formed on a paper that needs to be protected from counterfeiting, and the latent image and the background are divided into large dots and small dots to form prints. A technique has been developed that uses the difference to reproduce large dots in copying, but to eliminate small dots or to form latent characters and backgrounds into solid lines and dots. In order to make the printing plate film, even if the difference between the latent character and the background is very small, it is easy to identify the latent image. Also, when producing the film, the shade is adjusted according to the printing plate material (PS plate, Nairopan). There is a flaw.

이러한 결점을 보완한 본 발명은 점선(dash line)만으로 또는 선(solid line)과 점선으로 이루어진 잠상문자나 비표를 각도변환시키면 점선에 의한 현혹효과가 있으며, 여기에 현혹패턴을 삽입시키면 육안으로 식별이 블가능한 잠상패턴이 된다. 종래의 선으로 이루어진 각도변환 방법은 각도가 변하는 부분에서 선의 굴절과 간섭에 의해 농담 및 선의 굵기가 변하여 잠상문자나 비표가 쉽게 식별할 수 있으며 본 발명은 점선만으로 또는 점선과 선으로 이루어져 있기 때문에 각도변환 부위에서 농담 및 선의 굵기등의 변화가 있다.The present invention, which has solved this drawback, has a deceptive effect due to the dotted line when the latent character or the non-marked angle consists of only a dashed line or a solid line and the dotted line. This becomes a possible latent image pattern. Conventional angle conversion method consisting of the line is changed in the shade and the thickness of the line by the refraction and interference of the line at the angle change, so that the latent character or non-mark can be easily identified and the present invention consists of only the dotted line or the dotted line and the angle There is a change in the shade and line thickness at the conversion site.

본 발명은 복사시 원고의 방향이나 복사기의 주사선 방향에 관계없이 잠상문자나 비표가 돌출 또는 소실되어 복사된 것임을 쉽게 알 수 있음은 물론, 위 변조를 미연에 방지할 수 있는 잠상현출에 의한 복사위조 방지용지와 그 제조방법을 제공하려는 것이다.The present invention can easily know that the latent image or non-mark is copied by protruding or disappearing irrespective of the direction of the original or the direction of the scanning line of the copier during copying. It is to provide a prevention paper and a method of manufacturing the same.

본 발명은 피인쇄체 표면에 점선굵기 0.04-0.06mm, 점선간격 0.20-0.27mm, 점선길이 0.20-0.27mm로 된 점선(dash line) 또는 선굵기 0.04 내지 0.06mm, 선간격 0.30 내지 0.37mm로 된 선(solid line)과 선폭 0.1-0.27mm인 현혹패턴으로 구성되어 있으며, 배경으로서의 점선이나 선을 수평으로 볼때 잠상으로 나타내고자 하는 문자나 비표부분의 점선이 선은 배경으로서의 점선이나 선의 방향인 수평방향에 대하여 90도, 60도, 45도, 30도등 다양한 임의의 각도를 갖는 잠상을 여러개 배치하여 어느쪽이든지 점선이나 선의 방향이 복사기의 주사선 방향과 일치하도록 설계하였다.The present invention has a dashed line of 0.04-0.06mm, dotted line interval 0.20-0.27mm, dashed line length 0.20-0.27mm on the surface of the printed material, or a line thickness of 0.04-0.06mm, line interval 0.30-0.37mm It consists of a solid line and a dazzle pattern with a line width of 0.1-0.27mm, and the dashed line as the background or the dashed line of the character or non-marked part to be represented as a latent image when the line is viewed horizontally. Several latent images having various arbitrary angles such as 90 degrees, 60 degrees, 45 degrees, and 30 degrees with respect to the direction were arranged so that the direction of the dotted line or line coincided with the scanning line direction of the copier.

또 한가지 방법은 용지표면에 각도변화에 의한 잠상부분을 다수개 연접시키되 다수개의 잠상부분이 물결 무늬 형태로 이루도록 윗줄의 골 위치가 아래줄의 마루부분 위치와의 높이가 겹치거나 일치되도록 여러줄로 배치하였다.Another method is to connect a plurality of latent image parts due to the change of angle on the surface of the paper, but to make the number of the latent image parts in a wavy pattern so that the top row position overlaps or coincides with the bottom line position. Placed.

본 발명은 잠상패턴 복사시, 원고나 복사기의 주사선의 방향이 변하면 돌출되던 부분의 잠상문자나 비표가 반대로 소실되고 소실되던 부분이 돌출되어 어떠한 경우에도 잠상문자나 비표가 나타나게 되어 있다.When the latent image pattern is copied, when the direction of the scanning line of the original or copier is changed, the latent image characters or marks on the protruding portions are reversed, and the missing portions protrude and the latent image characters or marks appear in any case.

더우기 위에 기술한 점선 또는 선과 점선의 각도변환에 의한 잠상패턴에 현혹패턴을 추가시켜 넣으면 현혹선에 의해 육안으로는 거의 식별이 곤란한 잠상패턴이 된다.Moreover, when the dazzle pattern is added to the latent image pattern by the angle conversion of the dotted line or the line and the dotted line described above, the latent image pattern is hardly discernible by the naked eye due to the dazzle line.

이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Referring to the present invention as described above is as follows.

제 1 도는 용지(1)의 표면에 점선 또는 선으로 인쇄된 배경(2)과 각도변환된 점선으로 "복사"라고 표시된 잠상부분(3)을 인쇄한 본 발명의 개략도를 나타낸 것으로 배경(2)과 잠상부분(3)은 모두 점선으로, 또는 배경(2)이 선(solid line)일 경우 잠상문자(3)은 점선으로 구성되어 있어 육안으로는 배경과 문자가 구별되지 않는다.FIG. 1 shows a schematic diagram of the present invention in which a background 2 printed with a dotted line or a line on the surface of the paper 1 and a latent image portion 3 marked as "copy" by an angle-converted dotted line are printed. Both the latent image portion 3 and the dotted line, or when the background (2) is a solid line (latent image 3) is composed of a dotted line so that the background and the character is not visible to the naked eye.

제2도는 제 1도의 일부를 확대한 도면으로 잠상부분(3)을 구성하는 점선의 방향은 배경(2)을 구성하는 점선 또는 선에 대해 90도의 각도로 되어 있으며, 그 옆의 문자(31)는 배경(2)에 대해 45도로 구성되어 있다.FIG. 2 is an enlarged view of a portion of FIG. 1, wherein a dotted line constituting the latent image portion 3 has an angle of 90 degrees with respect to the dotted line or line constituting the background 2, and the character 31 next to it. Is composed of 45 degrees against the background (2).

제 3 도는 제 2 도의 용지가 복사된 도면이다. 화살표a는 복사기의 빛의 주사방향이며, 이 방향과 나란한 점선 즉, 제 2 도의 배경(2)은 소실a되고 주사방향과 어긋나 있는 점선 또는 선은 돌출b되어 잠상문자가 나타난다. 잠상문자가 90도와 45도로 구성되어 있기 때문에 원고의 방향을 바꾸어도 잠상문자가 나타나게 된다.3 is a copy of the paper of FIG. The arrow a is the scanning direction of the light of the copier, and the dotted line parallel to this direction, that is, the background 2 of FIG. 2 is lost a, and the dotted line or line deviating from the scanning direction is projected b to show the latent image. Since the latent character is composed of 90 degrees and 45 degrees, the latent character appears even if the original is changed.

제 4 도는 용지(1)의 배경(2)과 잠상부분(3) 위에 현혹패턴(4)을 넣은 실예를 보여주는 것이다. 이 현혹 패턴(4)은 배경(2) 및 잠상부분(3)와 제판구성을 동일하게 한 것으로 동시에 인쇄된다.4 shows an example in which the dazzle pattern 4 is placed on the background 2 and the latent image portion 3 of the paper 1. The dazzle pattern 4 is printed simultaneously with the same plate making configuration as the background 2 and the latent image portion 3.

제 5 도의 a는 제 4 도 용지의 점선이 복사기 주사선과 평행하게 복사한 예로서 잠상부분의 점선 또는 선이 주사선과 수직상태에 있으므로 잠상문자("복사")는 돌출하고 배경은 소실된다.In FIG. 5A, a dotted line of FIG. 4 paper is copied in parallel with the copier scan line, and thus the latent image ("copy") protrudes and the background is lost because the dotted line or line of the latent image portion is perpendicular to the scan line.

제 5 도의 b는 제 5 도의 a와 반대로 된 잠상패턴으로 복사시 복사물이 제 5 도의 a와 반대로 재현된다.B of FIG. 5 is a latent image pattern reversed to a of FIG. 5, so that copies are reproduced as opposed to a of FIG.

제 6 도는 용지(1) 위에 잠상부분(3)을 물결무늬 형태로 배치한 실시예를 보여주는 것이다.6 shows an embodiment in which the latent image portion 3 is arranged in a wavy pattern on the paper 1.

본 발명은 다음과 같은 특징이 있다.The present invention has the following features.

1. 인쇄물에 표현된 잠상부분과 배경이 모두 점선 또는 잠상문자가 점선일 경우 배경은 선(이와 반대일 수 있음)으로 이루어져 잠상부분의 옥안식별이 곤란하고 위장패턴으로 현혹되어 인쇄물이 똑같은 평면으로 나타나므로 이 인쇄물 위에 필요한 사항을 인쇄하거나 기입하여도 거부감이 없다.1. If both the latent image and the background of the printed image are dotted lines or the latent image is dotted, the background is composed of lines (which may be the opposite), which makes it difficult to identify the latent image of the latent image. As it appears, there is no objection to printing or filling out the necessary information on this printed matter.

2. 이 인쇄물에 사용한 점선 또는 선 배경에 대해 잠상부분을 이루는 점선 또는 선이 여러 각도(45도 90도 등)로 배치되어 있어 어떠한 방향으로 복사하여도 잠상부분이 나타나게 된다.2. The dotted line or line forming the latent image portion against the background of the dotted line or line used in this printout is arranged at various angles (such as 45 degrees and 90 degrees) so that the latent image portion appears in any direction.
