1. Temperature Setting: If the temperature is too low, it may result in poor or unstable hot stamping, and the printed pattern may appear blurred. Conversely, if the temperature is too high, it can cause oxidation on the surface of the color layer, leading to a loss of luster, darker colors, and in severe cases, bubbling. To determine the hot stamping temperature, consider the following factors: pressure, speed, area, and room temperature. The general temperature range for hot stamping is between 140℃ and 180℃. Once the temperature is set, it should be maintained consistently, with a ±2℃ fluctuation being ideal.

2. The pressure is indeed set: The standard pressure for hot stamping is typically 4-6 kg/cm². Insufficient pressure prevents the hot stamp foil from adhering to the substrate, reducing durability; excessive pressure, on the other hand, can cause the substrate to shrink and deform, leading to pattern distortion and a thinner printed layer. When stamping complex, uneven products, it is crucial to pay attention to the uniform distribution of pressure points. Higher pressure angles are required between the hot stamping roller and the substrate; otherwise, it is prone to partial adhesion issues.

3. Speed determination: It should be confirmed based on the烫印 area, while considering the power of the heating temperature. Generally, the sequence is first speed, then pressure, and finally temperature.

Heat transfer film products should be handled with care, placed upright, and never laid flat; they must not be placed near heat sources and should be kept away from them, typically stored at 25°C; they should be protected from moisture. Once damp, they will produce gas under high heat during use, causing a chemical reaction in the transfer film. Therefore, when storing and preparing for use, heat transfer films must be kept dry, away from moisture and pressure, and placed in a cool, well-ventilated, and dry location.
