Description

Anti-counterfeiting printed products by optical interference and latent image and manufacturing method

The present invention relates to an anti-counterfeiting printed product and a method for manufacturing the same, which allow to distinguish the color copy using light interference and latent image development.

Recently, with the development of optical devices, with the development of color image processing technology by computer, the color copier has changed from analog method to digital method, and the output method has been developed as a line conversion method and halftone intensity modulation copier. In addition, there is a concern that the appearance of counterfeit goods due to the copying of banknotes or securities by outputting a color copier to a computer.

Of these developed color copiers, CLC 550,700,800 color copiers, manufactured by Japan Canon, also installed a copy protection device for banknotes in 12 countries in Europe exclusively with Canon, and manufactured and sold before installing such banknote copy protection devices. The anti-counterfeiting technology for the CLC series (1,100,200,300,350,500) was developed by the present applicant, and Patent No. 107477 (Anti-counterfeit paper using optical interference) and Patent No. 104762 (Anti-counterfeit paper by latent image development) It is known as. However, Minolta's CF80 (developed in 1993), CF900 (developed in 1996), and Fuji Xerox's A Color 635 (developed in 1993) and A Color 936 (developed in 1996) color copiers offer excellent resolution and color copiers. There is a lack of means to prevent copy counterfeiting because it has the function to adjust the originals in the same way as the originals.

In other words, the technologies used to prevent counterfeiting of the color of natural colors have been used to prevent counterfeiting by optical interference patterns, to counterfeit prevention by the development of flat plate latent images, and to use natural inks and special inks mixed with time-varying and fluorescent materials. Copier toner or ink is printed in a color that cannot be reproduced, so that a color is not reproduced in color copying, a technology that exhibits a copy protection effect is known.

정도의 토너 입자 크기로 인하여 복사기의 재현성 한계는 50%의 망점면적율인 경우 25

이상의 선을 재현할 수 있음을 알았다.However, the development of the optical equipment has a lack of anti-counterfeiting effect by the printing method using a special technique as described above, and thus a new copy anti-counterfeiting technique is needed. Accordingly, the present inventors analyzed the radiation characteristics of the high-resolution color copier and the color copier interlocked with a computer. As a result, in the case of the digital method, the original is sensed through a CCD (Charged Coupled Device) array and the electrical signal is converted to a laser scanning device. The photo reproducibility is improved by exposing the photosensitive drum to the photosensitive drum. The copying method is based on the distance between the original and the document sensing device when the original is detected.

Due to the degree of toner particle size, the reproducibility limit of the copier is 25 for halftone area ratio of 50%.

It was found that the above lines can be reproduced.

(50-250 line/inch)의 간격을 가지는 선화를 복사하여 본 결과 4,5선/

(133 line/inch)이상인 직선은 부분 농도차이가 발생함을 알 수 있었다. 이러한 복사 농도차이의 원인으로는 디지탈 복사기의 경우 CCD(Charged Coupled Device) Array의 RGB Group 소자의 크기가 25.5

인 데에 따른 해상력 한계와, 첨부된 도면 제1도의 300% 확대도면에 나타난 것과 같이 레이저 주사시 주주사와 부주사 방향의 농도차이에 의한 것으로서, 천연색복사기의 해상도가 400dpi인 복사기의 출력방법이 선변환방식에서는 원고를 주주사방향과 부주사방향의 직선을 조밀(稠密)한 점으로 직선을 재현함으로서 복사농도 차이가 발생되기 때문이다.On the other hand, in the case of digital copiers (especially the color copiers described above (CLC series, CF80, CF900, A color 635, A color 936) or a color copier with a computer), the original is copied and reproduced by a pixel processing technique of halftone dots. In order to analyze the radiation characteristics of prints composed of line drawing, 0.1-10 lines /

Copying line drawings with (50-250 line / inch) spacing results in 4,5 lines /

A straight line over (133 line / inch) showed partial concentration difference. The reason for this difference in radiation density is that in the case of digital copiers, the size of the RGB group element of the CCD (Charged Coupled Device) array

The output method of a copier with a resolution of 400 dpi, which is a result of the resolution limit of the natural color copier, is due to the difference in resolution and the concentration difference between the main and sub-scanning directions during laser scanning, as shown in the 300% enlarged drawing of FIG. This is because, in the conversion method, the radiation concentration difference is generated by reproducing a straight line at a point where the original is dense in a straight line in the main and sub scanning directions.

Since printed materials such as banknotes and securities are mainly composed of line drawings, the method of printing by design technique using the limit of reproducibility when copying is examined. The optical interference pattern formed by adding partial dotted lines to spiral or concentric circles with regular intervals is a natural color because the color copier output method deforms regardless of the direction of the scan line or the original when copying in the copier copier. It is easy to see that it is copied by copier, but the copying method of natural color copier does not have the effect of anti-counterfeiting in the halftone intensity modulation method, and it is possible to prevent the forgery and alteration by applying a latent image pattern to it. And the latent image Hatton would like to provide.

The present invention is formed by combining the optical interference pattern and the latent image pattern on the printed matter, such as banknote, the optical interference pattern is a spiral circle (2) or dense concentric with a dotted line (4) and solid line (5) on the ground (1) The latent image pattern is formed by a circle (3), and the latent image pattern is characterized by forming both the latent image and the background by dotted lines. Furthermore, the latent image pattern is constituted by a deceptive pattern that dazzles the latent image or non-marking easily. Latent characters or non-marks consist of a dashed line that is lost during copying and a dashed line that is reproduced during copying. Thus, when copying a banknote, etc., which forms an optical interference pattern and a latent image pattern, to a color copier (CLC series, CF80, CF900, A color 635, A color 936) or a color copier with a computer, The latent image ratio table generated by the interference phenomenon caused by the angle meeting the direction and the resolution difference in the radiation direction causes the fan flying (propeller) shape (8), the wave pattern (7), or the latent image ratio to appear on the copied paper. The optical interference pattern or latent image pattern 6 is closely related to the resolution (thickness of the scanning line, etc.) and the original line thickness, the line interval of the original, the dotted line length, the dotted line thickness, the dotted line interval, and the dazzle pattern.

When the dotted line or the line as a background is viewed horizontally, the direction of the dotted line constituting the character or non-marked portion to be represented as a latent image is arranged at an angle of 90 degrees with respect to the horizontal direction as the dotted line, which is a dazzle pattern as the background, so that the natural color copier and the computer Designed to match the scanning line direction of the linked natural color copying machine.

In addition, the symbol, figure, or character 10 is superimposed on the spiral circle 2 having the optical interference effect or the latent image pattern having the latent image display effect on the dense concentric circle 3, as shown in FIG. 10. In such a case, when the color is copied to a color copier linked with a color copier (CLC series, CF80, CF900, A color 635, A color 936) and a computer, a wavy pattern 7 or a latent image ratio appears.

Of course, the micro-spaced spiral circles or the plurality of dense concentric circles as shown in Figs. 2 and 3 may be used in various printed matters in general graphic patterns, but the spiral or dense concentric circles partially combined with dotted lines as shown in Fig. 4 Is not used.

However, various printed materials using the spiral circle or multiple concentric circles shown in FIGS. 2 and 3 as graphic patterns are spiral or multiple finely spaced concentric circles represented in the original when copying with a color copier or a color copier linked with a computer.
