Abstract

The invention discloses an anti-counterfeiting coin / seal, and in particular relates to an anti-counterfeiting coin / seal with a perspective amplified pattern. The anti-counterfeiting coin / seal with the perspective amplified pattern consists of a coin or seal with an anti-counterfeiting pattern, and a micro lens array checking sheet for observing the anti-counterfeiting pattern, wherein the checking sheet and the coin or seal are respectively used independently and coordinately; the structure of the coin or seal with the anti-counterfeiting pattern is that a micro-pattern anti-counterfeiting pattern is directly printed on the surface of the coin or the seal; the structure of the micro lens array checking sheet is that a micro lens array structure is processed on a transparent medium sheet; and the specification of the micro lens of the checking sheet is matched with the structural dimension of the anti-counterfeiting micro-pattern. The amplified micro-pattern anti-counterfeiting information on the surface of the coin can be seen through the micro lens array of the checking sheet, and the amplified anti-counterfeiting pattern has a special effect of a three-dimensional shifting state by moving relative positions of an observation point and the coin. The anti-counterfeiting coin / seal has the better anti-counterfeiting effect and is convenient to identify.

Description

technical field [0001] The invention relates to an anti-counterfeit coin and stamp, in particular to an anti-counterfeit coin and stamp with a transparent and enlarged pattern. Background technique [0002] At present, there are many kinds of anti-counterfeiting technologies applied to coins and chapters, including edge anti-counterfeiting, material, pattern anti-counterfeiting, etc. However, compared with other fields, the application of coin anti-counterfeiting technology is relatively limited. In recent years, many image anti-counterfeiting technologies have been successfully applied to coins, and have achieved good anti-counterfeiting effects, such as invisible engraving, laser holography, color pad printing and other technologies, which have greatly improved the anti-counterfeiting technical content of coins. [0003] Coin designers are more willing to adopt anti-counterfeiting technology that intuitively expresses design ideas. The optical anti-counterfeiting technolo...
