What is the reason for the hot stamping machine after the hot stamping is completed or the hot stamp

a.Light pressure or low temperature. - Increase the pressure or increase the temperature and time.

b.The hot stamping material is not consistent with the hot stamping material - choose the appropriate hot stamping material.

C: Additives such as wax reducer and brightener are added to the ink of printed matter, and it is difficult for the hot-melt adhesive in the anodized aluminum hot stamping foil to bond with such additives even at high temperature and high pressure.

D: The printing ink layer on the substrate is too thick: the thickness of the ink layer of the background color of the substrate will prevent the adsorption of the adhesive in the anodized aluminum hot stamping foil on the substrate surface, so that the adhesion of the anodized aluminum hot stamping foil will decrease, resulting in hot stamping can not be or is not firm.

e: Ink crystallization: The surface of the ink is too smooth to make the adhesive in the anodized aluminum hot stamping foil adhere to it. In order to prevent ink crystallization, it is necessary to control the additives of the drying agent in the ink.

F: The selected anodized aluminum hot stamping foil is not suitable for the substrate, and it also affects the fastness of hot stamping.

The reasons for poor hot stamping or hot stamping are as follows:

1: Additives such as wax reducers and brighteners are added to the ink of printed matter, and it is difficult for the hot-melt adhesive in the anodized aluminum hot stamping foil to bond with such additives even at high temperature and high pressure.

2: The printing ink layer on the substrate is too thick: the thickness of the ink layer of the background color of the substrate will prevent the adsorption of the adhesive in the anodized aluminum hot stamping foil on the substrate surface, so that the adhesion of the anodized aluminum hot stamping foil will decrease, resulting in hot stamping can not be or is not firm.

3: Ink crystallization: The surface of the ink is too smooth to make the adhesive in the anodized aluminum hot stamping foil adhere to it. In order to prevent ink crystallization, it is necessary to control the additives of the drying agent in the ink.

4: The selected anodized aluminum hot stamping foil is not suitable for the substrate, and it also affects the fastness of hot stamping.

5: The hot stamping temperature is too low or the pressure is too small.

1.The hot stamping is not on or the hot stamping is not firm.

The hot stamping is not good or the hot stamping is not firm, that is, the anodized aluminum cannot be ideally transferred to the surface of the substrate or the anodized aluminum cannot adhere well to the substrate. The main reasons for the hot stamping or poor hot stamping are: low hot stamping temperature; Short bronzing time; The hot stamping pressure is not enough; Background ink contains paraffin; The base color of the printed matter is thick and smooth; The background ink of the printed matter dries too quickly and crystallizes, and the anodized aluminum model is not suitable.

2.Hot stamping and back-pulling phenomenon.

The so-called reverse pull refers to the fact that after hot stamping, the anodized aluminum foil layer is not firmly attached to the surface of the printed material background ink layer or white paper, but part or all of the background ink layer is pulled away by the anodized aluminum.

The main reason: the ink layer of the base color is not dry; Too much white ink is used in the base ink layer, which is easy to chalify. Solution: control the amount of dry oil; Mix the withdrawal agent with white ink; The hot stamping part is not inked.

3.Hot stamping** is easy to distort.

**The handwriting is hairy, the pen is broken, and the gloss is poor. The handwriting is hairy, which is due to the low temperature; The lack of pen and broken painting is generally caused by the excessive tension of the anodized aluminum coil or the lack of pressure; The poor gloss is due to the high temperature. Workaround:

Depending on the specific problem that arises, adjust the temperature to the appropriate temperature and pressure accordingly.
