Difference between IMAGE Micro-nano Optical Tech and Conventional Hologram
Micro-nano optical technology is achieved by a process similar as used in semiconductor industry, it has high graphic and text resolution, so it can write very fine text, the text or graphic height can reach 20 microns, and the precision is ten times higher than ordinary printing. Therefore it is often used for anti-counterfeiting encryption. Micro-nano structural can present the colors, contrast, dynamic and 3D effect of texts and graphics.
Hologram is a compound word, derived from the Greek, holos (all) + gramma (information), which is a technique for recording and reproducing all the optical information of an object. Narrowly speaking, it's a stereoscopic photo containing all three-dimensional information. Holography is just one of the methods to achieve the micro-nano structural diffraction colors.
IMAGE micro-nano techniques secure our IDs and documents with a higher technical threshold. Meanwhile, makes our IDs appearance artistic and easy to recognize and remember.
Micro-nanto Optical Technologies for Verifying and Protecting Identities
Incorporating micro-nano optical technologies into identities and documents, aiming to protect them from counterfeiting, and make them easy to authenticate, and offer the highest level of visual secure design.
Zero Level Optical Diffraction (Red and Green Rotation)
Under reflected light angle, color changes between red and green when rotate 90 degree. Unlike other holographic or rainbow colors, it shows a very pure and stable color changes effect. Easy to verify and very difficult to duplicate. A transparent hologram with stable color changes under reflected light angle, or metalized hologram with hidden graphics under big view angle.
Optical Guilloche
Composed of complex thin lines with a width of 0.3mm~0.1mm,which has a dynamic effect. These thin lines curve and overlap to create a complicated pattern on the surface of ID cards. The pattern can be easily verified, but too small to be effectively reproduced without original graphics.
3D Dynamic Effect
For visual appeal and a higher level of security, an optical security layer with 3D dynamic effects can be laminated on the ID card. Viewed from different angles, the image will change color. Under a specific angle, it can restore 3D natural colors, and even show some simple actions, such as flying birds, fluttering clouds, etc.
Micro Text
As a covert security features, micro text is quite difficult to reproduce and commonly used in passports and highly secure id cards. Micro text is text or graphics with a height of 50 μm to 10 μm, which cannot be recognized by the naked eye and requires a 80-100 times magnifying glass to read. It can be added as an extra security protection for credential products. Usually designed in level 2 or level 3 security.
