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 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.
