Description

Frosted holographic anti-counterfeiting paper and preparation process thereof

Technical Field

Background

At present, holographic graphics are popular to people as an effective and practical anti-counterfeiting technology, and are rapidly developed in scale. Laser holography is still the mainstream technology for public anti-counterfeiting internationally so far, and the characteristics of convenient identification, difficult imitation and easy mass production are difficult to replace by other anti-counterfeiting technologies in a short period of time. Holography and anti-counterfeiting are almost seen by people and the like, and it seems that the holographic trademark is the anti-counterfeiting trademark or the anti-counterfeiting trademark is the holographic trademark. Laser holography used for anti-counterfeiting in China begins in the eighties, and the ninety years are the tripod period of die-pressing holographic anti-counterfeiting. The short period of 91 to 93 years is at least two years, and 300 holographic anti-counterfeiting trademarks which are produced and operated by enterprises are newly created, and the scale of the holographic anti-counterfeiting trademarks ranges from dozens of thousands of yuan to thousands of yuan. With the wide application of holographic anti-counterfeiting and the emergence of other anti-counterfeiting technologies, people think about 32429for holographic anti-counterfeiting. The excessive manufacturers, the excessive products and the excessive competition can be the primary reasons that the die stamping holographic anti-counterfeiting falls into the trust crisis. The image source is simple, the photographic technology is old and the recording material is single, so that the counterfeit holographic trademark is inundated, and the source of the trust crisis is also induced. Therefore, how to take laser holography as the development direction of anti-counterfeiting technology is crucial to continuously mining the potential and innovation of products. The advent of a laser pixel holographic photoemission plate making system marks that the manufacture of a holographic plate has entered into a digital era from an analog era, so that the holographic plate making period is shortened to one or two days from the last ten days in the past, and the manufacturing cost is greatly reduced; meanwhile, the three-dimensional true color hologram is easier to realize and is practical.

However, the existing holographic anti-counterfeiting paper is difficult to be well combined with frosting, and the frosting can destroy the beauty and the whole shape of the holographic image, so that a paper which can well combine the holographic anti-counterfeiting paper with the frosting is needed.
