Embodiment 1
[0058] The local reverse UV printing method of the packaging box in this embodiment includes the following steps:
[0059] 1) cutting
[0060] Cut the cardboard to be printed to obtain the printing substrate;
[0061] 2) Offset printing
[0062] Four-color ink printing is carried out on the printing substrate, and it is cured by ultraviolet light;
[0063] 3) Add 35 parts of urethane acrylate and 20 parts of polybutadiene acrylate into the mixer, stir for 5 minutes at a speed of 1500 rpm, then add 8 parts of primer filler, stir for 2 minutes at a speed of 800 rpm, and then add 10 parts of primer photoinitiator part, stirred at a speed of 1000rpm for 30min, then added a base oil additive, which consisted of 5 parts of a leveling agent and 5 parts of a dispersant, then stirred at a speed of 600rpm for 10min, and filtered through a 500-mesh gauze to obtain reverse primer;
[0064] Among them, the base oil filler is talc powder; the base oil photoinitiator is 2,4,6 (trimethylb...
Embodiment 2
[0070] The local reverse UV printing method of the packaging box in this embodiment includes the following steps:
[0071] 1) cutting
[0072] Cut the cardboard to be printed to obtain the printing substrate;
[0073] 2) Offset printing
[0074] Four-color ink printing is carried out on the printing substrate, and it is cured by ultraviolet light;
[0075] 3) Add 30 parts of urethane acrylate, 20 parts of polybutadiene acrylate, and 20 parts of trimethylolcyclohexyl acrylate into the mixer, stir at a speed of 1800rpm for 2min, then add 12 parts of primer filler, Stir at a rotating speed for 5 minutes, then add 8 parts of primer photoinitiator, stir at a speed of 1200rpm for 20 minutes, then add a primer additive, which consists of 5 parts of a leveling agent and 10 parts of a dispersant, and then stir at a speed of 500rpm 20min, adopt 500 mesh gauze to filter, make reverse base oil;
[0076] Wherein, the filler is talcum powder; the primer photoinitiator is 2-benzyl-2-dime...

[0082] The local reverse UV printing method of the packaging box in this embodiment includes the following steps:
[0083] 1) cutting
[0084] Cut the cardboard to be printed to obtain the printing substrate;
[0085] 2) Offset printing
[0086] Four-color ink printing is carried out on the printing substrate, and it is cured by ultraviolet light;
[0087] 3) Add 50 parts of polyurethane acrylate, 30 parts of polybutadiene acrylate, and 30 parts of trimethylolcyclohexyl acrylate into the mixer, stir at a speed of 1600rpm for 4min, then add 10 parts of base oil filler, Stir at a rotating speed for 3 minutes, then add 9 parts of primer photoinitiator, stir at a speed of 1100rpm for 25 minutes, then add primer additive, which consists of 4 parts of leveling agent, 6 parts of dispersant, and 2 parts of defoamer. Then stir with the rotating speed of 600rpm 10min, adopt 500 order gauze to filter, make reverse base oil;
[0088] Among them, the base oil filler is composed of talc...
