The principle of the laser imprint transfer process is to combine the embossed film with laser micro-grooves that can be used multiple times with UV varnish. After UV curing, the laser embossed film is peeled off, and the cured UV varnish is cured. The surface forms a laser micro-groove that is the same as the surface of the laser embossed film. By refracting or diffusing the natural light, the visual effect can be enhanced. The effect of the laser imprint transfer product is shown in Figure 1. The process schematic is shown in Figure 2.

The advantages of the laser imprint transfer process are: 1 Compared with the traditional hot stamping foil, the laser embossed film is very environmentally friendly, and can be made by pressing the heated laser nickel plate on the PP film, and the traditional hot stamping The printing foil needs to be coated on the PET film with a plurality of chemical components such as a release layer, an embossed layer, an aluminized layer and a glue layer; 2 the cost of the laser embossed film is lower than that of the conventional hot stamping foil, and there are many types. And can be used more than 3 times; 3 can be used for local laser imprinting transfer; 4 simple process, low scrap rate.
