Cigarette packet printing method based on UV printing ink for screen printing and UV printing ink for screen printing cigarette packet

The invention relates to the technical field of novel printing ink, cigarette packet printing and the like, and provides a cigarette packet printing method based on UV printing ink for silk-screen printing and the UV printing ink for silk-screen cigarette packets. The printing ink is prepared from the following materials in percentage by weight: 40 to 60 percent of polyester matte resin, 10 to 25 percent of polyurethane easy-extinction resin, 20 to 30 percent of skin-feeling resin, 4 to 5 percent of photoinitiator, 2 to 5 percent of smooth aid and 2 to 3 percent of wax aid. According to the method, the produced skin-touch UV ink for silk-screen printing is printed on a cigarette packet substrate and then is dried and cured by a UV lamp to obtain a cigarette packet containing a printing layer of the skin-touch UV ink for silk-screen printing, so that the shape stability and scratch resistance of a cigarette packet printing piece are improved, the ink color explosion during line cutting is avoided, the energy c
