Abstract: An anti-forgery method and anti-forgery products using micro-holes or pits are disclosed. The micro-holes or pits are formed in a respective protective pattern on each protected solid article. This random distribution of the micro-holes or pits has a predefined measurable distribution characteristic providing corresponding information that is registered, and used to identify the distribution of micro-holes or pits in the protective pattern on each protected solid article. Because the distribution of the micro-holes or pits formed in accordance with the invention is highly complex and randomly generated, it is unique and cannot be reproduced. Therefore, the effectiveness of the anti-forgery method is highly reliable and, unlike other methods, it is applicable to certificates and bills.

Abstract: A counterfeit-resistant document comprises a contrasting layer and a dynamic camouflaging layer. The contrasting layer is highly contrastive and includes a latent message that can be reproduced over a broad range of copy device control settings. The dynamic camouflaging layer is applied over the contrasting layer to suppress the latent message. The visual density of the dynamic camouflaging layer, which comprises a camouflage pattern that is printed in thermochromic ink, inversely varies with temperature. In this manner, the dynamic camouflaging layer is inactivated at room temperatures so that the latent message is suppressed on the original document, and activated at scanning temperatures so that the latent message is exhibited on a reproduction of the original document.

Abstract: This invention pertains to a printed matter in which it is difficult to confirm an image in the state before the image appears, and by scratching the print surface with a coin a brilliant image appears. On a print substrate, an image of a ink composition containing a material having a greater hardness than that of the metal of a coin or medal, and a print layer having a contrast with respect to the print substrate or the image are printed. By effectively using human visual recognition characteristics, the print layer having a contrast is recognized very strongly, so that the masking effect and the effect of attention occur. This makes it difficult to recognize what image is printed not only when the printed matter is seen from front, but also when it is seen sidewise. Thus, even if light is shed on the printed matter, the image cannot be seen.

Abstract: A method of manufacturing a thread-inserted window paper produces paper in which a thread is exposed to windows which are intermittently formed, and have clear contours, and in which thread is exposed surely at the window portions to make the thread clearly recognizable visually. The method is capable of being carried out with a relatively simple apparatus. Wet paper (1) in which a thread (T) is embedded in the paper layer is guided while being in intimate contact with a center roll (3) having protrusions (2) arranged on the surface thereof intermittently at a predetermined distance, the surface of the wet paper on the protrusions is frictionally rubbed by a friction roll (4) thereby moving fibers at the surface of the wet paper on the protrusions to form exposed portions of the thread intermittently on the surface of the wet paper and the wet paper is then dried by a customary method.

Abstract: A security document (1), such as a bank note, is formed from a sheet-like substrate (10) of clear plastic 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 flat 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 for 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.

Abstract: A planar form or structure is used to create a thin card capable of receiving and retaining printed indicia, including written signatures, on both opposing surfaces. The structure and related method allow the exposed carrier surface and the underlying release agent layer to receive and retain printed indicia, including written signatures, while retaining an extremely thin, yet tear-resistant, card structure. The release agent layer solidifies from a liquid to form a film capable of receiving and retaining printed indicia, written signatures, and the like which may be printed or written upon through the peeling away of the transparent lamina layer to expose the underlying release agent layer for receiving the indicia. The resulting structure preferably exhibits a flexibility due to its thickness lying within the range of 15-30 microns plus the thickness of the carrier.

Abstract: A moire pattern technology about a dot matrix hologram for hiding a moire pattern is invented. In the moire pattern hidden region of a dot matrix hologram, the moire pattern foreground area and the moire pattern background area are formed identically by interlacing bright lines and dark lines. While position shifting is formed between the lines of the two areas. This position shifting is several times of the size of the grating dots. Thus, a moire pattern hidden in the moire pattern hidden region without being processed specially has a poor hiding ability. Often the above moire pattern can be identified by eyes directly without using a decoding film. Therefore, such kinds of moire patterns have poor hidden effects. However, the moire pattern of the present invention can prevent the aforesaid phenomenon by a well designed pretended pattern. Moreover, the appearance of such a dot matrix hologram can be beautified by the addition of the pretended patern.

Abstract: Tamper-evident electric paper is made of two sheets of electric paper bonded together, the bottom sheet of which includes a pattern. Any attempt to erase a writing on the top sheet of electric paper results in the pattern on the bottom sheet of electric paper being erased. Therefore any tampering by erasure of a writing on the tamper-evident electric paper is revealed by the absence of a portion of the pattern on the bottom sheet of electric paper. Single sheet tamper-evident electric paper has a complex pattern, such as an encryption, printed on a single sheet of electric paper. Any attempt to erase a writing on the electric paper also erases a portion of the encryption, thereby providing evidence of tampering.
