Embodiment 1
[0028] The present invention is a kind of cigarette case printing process, comprises the following steps:
[0029] (1) Cut the printing substrate according to the packaging requirements of the packaged object;
[0030] (2) The surface of the printed substrate that has been cut in step (1) is pressurized through a dot grating mold, so that the surface of the printed substrate forms a groove pattern;
[0031] (3) transferring the silver paste mixture into the grooves of the groove pattern pressed in step (2) by gravure printing;
[0032] (4) Hot stamping is performed on the groove of the surface of the printed semi-finished product completed in step (3) by hot stamping with a hot stamping machine;
[0033] (5) Coating the curable resin on the surface of the printing substrate by screen printing on the surface of the printed semi-finished product treated in step (4);
[0034] (6) Cut the polyethylene heat-shrinkable film according to the size of the printed substrate cut in ste...
Embodiment 2
[0048] The difference between this example and Example 1 is: after the step (9) is completed, before the polyethylene heat shrinkable film is attached to the surface of the printing substrate, the polyethylene heat shrinkable film after the step (9) is completed is baked Dry processing, the drying temperature is 150 degrees Celsius. In the step (8), the irradiation time of the ultraviolet curing lamp is 5 seconds, and the total power of the ultraviolet curing lamp is 10 kilowatts. When the silver paste mixture is transferred by gravure printing in the step (3), the contact time between the gravure and the surface of the printing substrate is 8 seconds.
Embodiment 3
[0050] The difference between this example and Examples 1 and 2 is that: before the polyethylene heat shrinkable film is attached to the surface of the printing substrate after the step (9) is completed, the polyethylene heat shrinkable film after the step (9) is completed Carry out drying treatment, and drying temperature is 120 degrees Celsius. In the step (8), the irradiation time of the ultraviolet curing lamp is 4 seconds, and the total power of the ultraviolet curing lamp is 10 kilowatts. When the silver paste mixture is transferred by gravure printing in the step (3), the contact time between the gravure and the surface of the printing substrate is 7 seconds.
