1. The hot stamping machine must select the appropriate hot stamping foil according to the different types of the material being heated. Hot stamping must grasp the temperature, pressure, hot stamping speed three-way cooperation, and according to the hot stamping materials, hot stamping area and the difference is different, hot stamping area is too large, it is necessary to do some hollow, but if a large area Hot, thin ink layer, then do not need to hollow out, direct hot no problem, thick ink layer is the need to hollow out, and this is also a good relationship with the quality of aluminum.
2, in addition to printing ink dry oil too much, if it is the best color bronzing is best hollowed out.
3, aluminum foil hot stamping foil should use attributes suitable for paper, ink (especially black ink), kerosene, composite glue, stamping parts must be kept dry, so as not to cause oxidation or damage to the hot stamping layer.
4, the general packaging: a roll of 64cm × 120m, a box of 10 rolls; customizable width of 64cm, length 120m or 360m large rolls or other special specifications.
5, in addition to materials, the temperature will also affect the foil hot stamping off phenomenon, in addition, the machine can not be ignored abnormal.
6. Sometimes changing the gold foil is also a good consideration. In fact, we must pay attention to the glue under the gold foil. We can find the supplier before the change and tell him our needs. Then the stock test, the same sheet, the same temperature The effect of gold materials of different manufacturers is not the same, the test is as follows:
a. First confirm that the quality of the galvanized aluminum foil is worse than the previous one;
b. If there is no problem with the quality of the electro-aluminum foil, it may be that the telephone aluminum foil does not match the performance of the ink;
c. May be ink is not dry or use excessive desiccant dusting.
