Usually mentioned holographic hot stamping divides into positioning and non - positioning hot stamping. Positioning hot stamping pattern is unified, with anti-counterfeiting function; Non-positioning hot stamping pattern is regular distribution, anti-counterfeiting effect is not so good, often used for anti-counterfeiting requirements are not too high on the packaging of goods.
Positioning hot stamping label adopts electric eye to locate hot stamping pattern position. Positioning hot stamping label can be positioned with single electric eye or double electric e
ye. It has higher technical difficulty and higher anti-counterfeiting efficiency than ordinary full-plate hot stamping film.
The positioning stamping foil is to combine a good laser holographic image anti-counterfeiting technology with hot stamping decoration technology, so that the product in improving the decoration at the same time to add more anti-counterfeiting performance. Laser hologram file is made by spatial frequency coding based on the principle of laser interference. Due to the its color, obvious layers, vivid image, varied optical transformation effect, high information and technology content, it began to be used in the field of anti-counterfeiting in the 1980s.
The use of holographic positioning hot stamping technology on packaging can not only increase the anti-counterfeiting function of packaging, but also improve the packaging decoration effect, is a popular packaging anti-counterfeiting technology in the world today.
Nowadays, holographic positioning hot stamping is not a new technology, but it is still an advanced technology in the field of hot stamping.
