Full-color reflection hologram anti-counterfeiting technology upgrade to ensure product safety

With the progress of science and technology, the phenomenon of making and selling fake products is becoming more and more rampant, and the security problem has been paid more and more attention by the public. The holographic anti-counterfeiting with low production cost and high anti-counterfeiting performance is especially favored by relevant enterprises.

Recently, the British start-up Iris Photonics has good news. Three individuals with decades of experience in the high-tech industry and engineering took two years to develop a breakthrough technology for security holograms.

This new type of hologram can quickly generate a large number of unique images of full-color security holograms, and allows each one to be personalized. This unique nature and production process, suitable for high security level items.

This hologram's ability to mix colors can produce a stable, full-color image that attracts consumer attention. Even rapid creation allows for differentiated hologram numbering and other personalization, says its co-developer, Wiltshire Athan Henry. This patented technology has very high security barriers and will be difficult for counterfeits to copy for a long time.

A mass production system for full-color reflection holograms has now been developed, enabling mass production. The technology will be used in high-security areas such as identity documents, pharmaceuticals and healthcare.

Holographic anti-counterfeiting is a new type of anti-counterfeiting technology developed by laser holographic technology, also known as laser holographic anti-counterfeiting. After decades of development, laser holographic anti-counterfeiting products have gradually upgraded from the initial holographic anti-counterfeiting logo to the second generation, third generation and even fourth generation holographic anti-counterfeiting technology.

The first generation of holographic anti-counterfeiting technology is laser embossed holographic image anti-counterfeiting. Using imprint holographic technology, the holographic surface structure is transferred to the polyester film, and the image is made on the plastic film by laser plate making, resulting in a colorful diffraction effect.

Second generation improved laser holographic image anti-counterfeiting technology. There are three main improved technologies: one is the application of computer image processing technology to improve the holographic image; the second is the transparent laser holographic image anti-counterfeiting technology; the third is the reflective laser holographic image anti-counterfeiting technology.

The third generation of encrypted holographic image anti-counterfeiting technology. The encrypted hologram image refers to an encrypted image that is invisible or becomes some speckle by encrypting the anti-counterfeiting image using optical image encoding encryption techniques such as laser reading, optical miniaturization, low-frequency lithography, random interference fringes, moire fringes, etc. Fourth generation laser holographic anti-counterfeiting technology. The amount of information is large, the production process is complex, and it is difficult for counterfeits to imitate.
