Hot stamping technology relies on thermal transfer printer for production and processing. Paper objects such as certificates, greeting cards, business cards, gift boxes and desk calendars can be re-processed by hot stamping, and materials can also be processed by hot stamping on other mobile phone cases, textiles and coating objects. Hot stamping is an important processing method for decorating the surface of plastic objects, which is not only used in paper, but also frequently used in electrical and electronic consumer products, such as hot stamping logo names. Electrolyzed aluminum is the main material for hot stamping, which is composed of polyester film substrate and transfer printing layer.
Four steps of hot stamping
First. the hot stamping foil contacts with the base material;
Secondly, the thermal transfer layer subjected to heat energy is fused and transferred to the surface of the substrate by pressure;
Third. automatically releasing the pressure after the transfer printing is completed, and automatically peeling the polyester film;
Finally. When the hot stamping is completed, the hot stamping foil moves forward automatically, and is replaced with the printing piece to be hot stamped.
In addition to considering the base material, hot stamping machine (thermal transfer machine), hot stamping machine fixture and backing plate, the most important thing is the level of cooperation among temperature, pressure and hot stamping time.
Advantages of hot stamping technology
1. Even after repeated machine cleaning, the image will not fade, and the edge is still clear.
2. Meet the requirements of green and safe products.
3. The pigment can be firmly fixed on the coating.
4. It's very firm, and it won't be damaged in any way.
5. Hot stamping does not spread, which greatly saves energy and improves picture clarity.
6. Stainless steel tableware, knives, sanitary ware, building ceramics and other industries are favored.
Many friends in the printing industry know that there are many hot stamping machines, such as plane hot stamping machine, plateless digital bronzing machine, flat hot stamping machine, ribbon ribbon ribbon hot stamping machine, etc. However, in the process of hot stamping production, according to the principle of thermal transfer technology, the re-production process is transferred by heat energy and pressure to have strong high hardness adhesion, and the hot stamping effect is perfect and clear, with good reduction, strong expressive force and gorgeous colors.
