Temperature has a significant impact on hot stamping, and it must be controlled within the corresponding range to ensure that the dye resin layer and adhesive melt moderately, in order to ensure good transfer of the aluminum layer. If the temperature is too high and the melting is excessive, the aluminum foil around the hot stamping image and text will also melt and fall off, resulting in a paste. At the same time, high temperature will cause chemical changes in the aluminum dyeing resin and aluminum layer, resulting in a decrease in the brightness and loss of metallic luster of the hot stamping product, and even causing the imprint to appear foggy or foamy; But if the temperature is too low and the melting is not sufficient, it can also cause the hot stamping to be difficult or not firm, the imprint to be weak, easy to fall off, or the pen to break or the imprint to be blurred.
