Water-resistant surface printing process for color packaging box with excellent adhesive force

The invention relates to the field of packaging box printing, in particular to a water-resistant surface printing process for a color packaging box with excellent adhesive force. Comprising the following steps that S11, on an automatic production line, primer is sprayed on the outer surface layer of the packaging box base plate, and the packaging box base plate enters a baking section to be dried; s12, a pattern mold is used for automatically pressing a pattern groove in the packaging box base plate coated with the primer; s13, a pattern groove obtained in the step S22 is automatically filled with pigment, and the pattern groove enters a baking section to be dried; and S14, in the water-resistant coating spraying section, the surface of the packaging box base plate filled with the pigment is sprayed with water-resistant coating, the packaging box base plate enters a baking section to be baked, and the water-resistant packaging color box with the excellent adhesive force is obtained. The water-resistant surfac
