US12723849 - Shooting color-changing target paper and manufacturing process thereof
The present disclosure provides a shooting color-changing target paper and a manufacturing process thereof, comprising a substrate paper layer, a BOPP optical film layer which is provided above the substrate paper layer and a UV-printing ink layer which is provided above the BOPP optical film layer. The manufacturing process comprises: S 1 : preparing a substrate; S 2 : attaching a BOPP optical film; S 3 : placing the substrate on a printing device; S 4 : printing a target paper pattern; S 5 : curing with a UV lamp; and S 6 : packaging a finished product. According to the present disclosure, the BOPP optical film layer is attached to the substrate paper and then the target paper pattern is printed on the optical film through UV without repeated printing. By drying and curing the ink through the UV lamp, the produced target paper may be immediately packaged for use without ventilation and drying, resulting in a higher production efficiency.
