The essence of hot stamping is the transfer process, which is the process of transferring the pattern on the surface of the aluminum foil to the substrate by the action of heat and pressure. When the plate is heated to a certain degree with the attached electric heating plate, it is imprinted through the aluminum foil and the paper, and the adhesive layer, metal aluminum layer and color layer attached to the polyester film are transferred by the effect of temperature and pressure. Printed on paper. Hot stamping has become an indispensable new processing technology in the printing and packaging industry. The bronzing process consists of traditional stamping and special stamping.
First, hot stamping specific process
Printed or sprayed photosensitivity hot stamping process: ink, drying, film exposure, hot stamping, finished product.
1, with 200 mesh ~ 300 mesh full screen brush photosensitive ink or with a spray gun to spray the substrate to be hot stamping. Liquid sensitizing ink is a transparent varnish that is specially used for various hot stamping. With excellent photographic performance, a very high minimum line width of 0.05mm.
2, dry. Dry with blowing air or dry with a screen-baking baking box. Note that the temperature can be around 40 degrees.
3, film exposure. The computer is used to design and print the necessary hot stamping images, and the film is output for UV exposure. After exposure to ultraviolet light, the photosensitive film of the non-patterned portion becomes thermoset, and the pattern portion is still thermoplastic.
4, hot stamping. In the hot stamping process, the adhesive layer of the gold and silver hot stamping foil and the thermoplastic part of the photosensitive film are integrally bonded by hot melt and do not adhere to the thermosetting part, thereby realizing thermal transfer of the hot stamping film. Hot stamping equipment can be used for plastic stamping machine, electric iron, heat transfer machine for hot stamping. The temperature can be controlled from 100 to 130 degrees.
5, hot stamping products. After hot stamping, the excess hot stamping film was gently peeled off into a dazzling finished product.
Second, special hot stamping has the following advantages:
1, hot stamping temperature is low, 100 to 130 degrees can be.
2, suitable for large area, fine line graphics hot stamping.
3, suitable for small batch, multi-type personalized stamping products production.
4, in the hot stamping process without the need to produce metal letterpress, low cost, fast, as long as there are positive negative film can be hot stamping.
5, hot stamping substrate is not limited, such as: all kinds of plastic film, paper, leather, metal, glass and so on.
6. Good adhesion to the hot stamping substrate. Photosensitive film after curing, with high brightness, no yellow, no scratch characteristics.
