The Transformation Road of Laser Holographic Label Technology

In this issue, we share the technical principles used in laser holography in anti-counterfeiting labels and introduce several commonly used holographic labels of different styles.

Holographic anti-counterfeiting is a new type of anti-counterfeiting technology developed by laser holographic technology, also known as laser holographic anti-counterfeiting. Using the principle of double beam interference, the phase can be "combined" by making the object light and another beam (reference beam) coherent with the object light generate an interference pattern, so that the phase and amplitude can be recorded simultaneously with the photosensitive negative, and holographic images can be obtained. At any time other anti-counterfeiting technology progress, holographic anti-counterfeiting has also been a new development and application.

At that time, the first generation of holograms had two serious problems. One was that the original image and the conjugate image were inseparable, and the other was that the coherence of the light source was too poor. Therefore, in the past ten years, the progress of holographic technology has been slow. And with the passage of time, laser holographic image production technology has spread rapidly, and now it has been breached by counterfeiters from all aspects, almost completely losing the ability of anti-counterfeiting. People have to start looking to improve the existing 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. 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.

1. Holographic anti-counterfeiting label.

Holographic anti-counterfeiting labels are suitable for high-end tobacco and alcohol, cosmetics, jewelry, electronic products, sporting goods and other industries. Single-layer labels can be used to change two-dimensional codes, logistics codes and anti-counterfeiting codes, and cooperate with two-dimensional code system functions to achieve the combination of digital and physical anti-counterfeiting.

2. Photolithography holographic uncover double-layer anti-counterfeiting label.

Photolithography holographic anti-counterfeiting label is an anti-counterfeiting label completed by using laser color hologram plate making technology and molding copy technology. The plate making technology that can be realized includes: dot matrix dynamic light, one-time special laser film, 3D optical miniature background, colorful optical random interference, Chinese and English uranium shrink text, etc.

3. Rainbow holographic double-layer anti-counterfeiting signature.

Rainbow holographic double-layer label technology, double-layer color, rich in rich variable and anti-counterfeiting information. Lift the label surface and flash the underlying label with verification information. With rainbow holographic or laser materials, the double-layer anti-counterfeiting label is beautiful, high-grade and dazzling. The double-layer scheme makes the label rich in more abundant product publicity and anti-counterfeiting information and increases the added value of the product.

In short, the upgrading of the times, science and technology are constantly developing, but also promote the progress of anti-counterfeiting technology. The combination of new ideas, new technologies, new materials and anti-counterfeiting technology, improving quality and green environmental protection is the important direction of the development of anti-counterfeiting technology. Dingxun Technology can customize various personalized anti-counterfeiting label solutions for different customers and products.
