What issues should be paid attention to in the process of customizing gift boxes?
First, pay attention to the change of ink in gift boxes.
The ink of the ink fountain flows out from the gap between the ink fountain roller and the ink fountain blade, and is naturally squeezed out by the ink. Therefore, the amount of ink in the ink fountain will directly affect the ink product. In addition, printing ink is thixotropic. If it is left in the ink fountain for a long time, the fluidity will deteriorate over time. Therefore, it is necessary to frequently stir the ink knife in the ink fountain or install an ink stirrer.
Second, pay attention to the dirt on the back of the gift box.
The dirt on the back is caused by the slow drying of the ink, the thick layer of the graphic ink, and the high smoothness of the paper. Therefore, this causes the ink on the surface of the printing paper to adhere to the back of the previous printing paper.
Third, pay attention to changes in water supply when making gift boxes.
Pay attention to the changes in the water supply at the beginning of the formal printing. There will be some changes in the water consumption for trial printing and after the formal printing. Need to pay attention to whether the proofs have ghosts or water scorpions, and also pay attention to mediating the water supply of the printing plate. If the water supply is too small, the printing plate will become dirty; too much water will cause the ink to emulsify, which will cause a series of problems, such as dull printed matter, stretched paper but not overprinted, delayed ink drying, and so on.
