Holographic hot stamping technology, according to the characteristics of the holographic pattern logo, is divided into continuous pattern hot stamping and independent pattern stamping. Independent pattern printing is the so-called holographic positioning hot stamping technology, the actual application of time is not long, it is a new high-tech. The use of the key materials of holographic electrochemical aluminum production is difficult, the process is extremely complex.
  
Holographic electrochemical aluminum is produced according to the principle of laser interference principle using the method of spatial frequency coding. The holographic pattern marks are arranged in a regular pattern on the anodized aluminum, and each pattern is provided with a positioning cursor. The working principle of machinery and equipment location identification system of laser electronic eye by irradiation of a cursor, the feedback information to the equipment processing center (airborne computer), followed by computer to skip step motor a jump step size and distance instruction, so as to realize the positioning.
  
Holographic electrochemical aluminum and mechanical and electrical equipment directly related to the accuracy of holographic positioning, which involves not only security, but also affect the beauty of the product. The holographic anodized pattern strictly speaking must be isometric, anodized aluminum production process inevitably produce errors due to, with the increase in the number of pattern errors in continuous quantitative accumulated to certain degree it will have a larger space, which will affect the positioning precision. The positioning accuracy of the machine equipment positioning system has a very important influence on the holographic positioning accuracy. Holographic positioning requires a high degree of accuracy, the general requirements of control within 0.2 mm; equipment operating speed should be moderate, too fast or too slow will cause the deviation of the positioning.
