With the wide application and anti-counterfeiting upgrade of the holographic electrochemical aluminum film in the printing and packaging industry, the anti-counterfeiting requirement on the holographic electrochemical aluminum is higher and higher. At present, manufacturers with holographic electrochemical aluminum production experience can easily imitate the same holographic electrochemical aluminum, so that the holographic electrochemical aluminum cannot meet higher anti-counterfeiting requirements, but with the upgrade of the photoetching technology, brand-new holographic electrochemical aluminum films developed by the traditional laser holographic technology, such as ' cat eye ', ' embossment ', ' dynamic grating ', ' dynamic silver sand ', ' 3D animation ', point light source reconstruction ' and the like, have single color decoration effect and anti-counterfeiting effect.
At present, the method for manufacturing the holographic true color widely applied to the printing and packaging industry is to thermoprint an electrochemical aluminum film on paper by temperature and pressure and then print the color on the electrochemical aluminum film thermoprinted on the paper by offset printing.
The existing method for making holographic true colour is that firstly an electrochemical aluminium film is thermoprinted on the paper (there is first contraposition overprinting), then the secondary gumming machine is used for printing (there are also four colours and hologram overprinting, the overprinting is most difficult once), because of the increase of multiple overprinting and printing procedures, the fluctuation of overprinting is large, the overprinting error is large, the printing rejection rate is high, and said technological method has not been used on paper package.
The existing holographic electrochemical aluminum film plays a role in anti-counterfeiting and decoration effects on printed packages, but the existing holographic electrochemical aluminum photoetching technology is limited to cat eyes, embossment, dynamic gratings, dynamic silver sand, 3D animation and point light source reproduction, and the photoetching technologies are only simple holographic photoetching effects and do not have true color reduction effects.
The holographic electrochemical aluminum film is widely applied to the printing and packaging industry, so that the anti-counterfeiting requirement on the holographic electrochemical aluminum is higher and higher. At present, manufacturers with holographic electrochemical aluminum production experience can easily imitate the same holographic electrochemical aluminum, so that the holographic electrochemical aluminum cannot meet higher anti-counterfeiting requirements.
