Preprinted security printing film

Patent Application No.4
Has passed preliminary review
A pressure-sensitive, thermal preprinted anti-counterfeiting film, referred to as preprinted anti-forgery transfer film. It preprints multiple anti-counterfeit printing ink patterns on the transfer film to make it have multiple anti-counterfeiting effects, and then transfers it to the substrate in a pressure-sensitive or heat-sensitive manner; so that the product packaging printing has a beautiful multiple anti-counterfeit At the same time, it is extremely convenient to use. For example, on the printed matter, there is a pattern of red-heavy yellow crane towers that have been pressure-sensitively transferred. Many “WD” letters have been engraved on the surface with a laser, visible to the naked eye, and red in the heat and the “Wu Da” at the bottom are revealed. When using an infrared lens, the word "printing system" appears. The anti-counterfeiting transfer mold temperature change security, laser anti-counterfeiting and infrared anti-counterfeiting on a map, and only one way to pressure sensitive or thermal transfer to the substrate, so that the product is greatly improved the difficulty of counterfeiting. In addition, there is a combination of more anti-counterfeiting features such as more ultraviolet and light changes, and a pre-printed anti-forgery transfer film, which can greatly protect the goods and facilitate market competition.
