Special hot stamping process and advantages

the essence of hot stamping is transfer printing, which is the process of transferring the pattern on electrochemical aluminum to the substrate through the action of heat and pressure. When the printing plate heats up to a certain degree with the attached electrothermal base plate, it is imprinted with the paper through the electrochemical aluminum film, and the adhesive layer, metal aluminum layer and color layer attached to the polyester film are transferred to the paper by using the effect of temperature and pressure. Hot stamping has become an indispensable new process in the printing and packaging industry. Bronzing process consists of traditional bronzing and special bronzing

I. specific process flow of hot stamping

printing or spray printing photosensitive hot stamping process: ink, drying, film exposure, hot stamping, finished products

1. Use a 200 ~ 300 mesh silk full-scale brush to keep the instrument clean, parts and accessories complete, safe photosensitive ink or spray the substrate to be hot stamped evenly with a spray gun. Liquid photosensitive ink is a kind of transparent varnish, which is specially used for all kinds of hot stamping. It has excellent photosensitivity, high graphics resolution and a minimum line width of 0.05 mm

2. Dry. Use electric wind to dry or use silk plate oven to dry, and pay attention to the temperature of about 40 degrees

3. Film exposure. Use the computer to design and make the required hot stamping pictures and texts, and output the negative for ultraviolet exposure. After UV exposure, the photosensitive film of the non pattern part becomes thermosetting, and the pattern part is still thermoplastic

4. Hot stamping. In the process of hot stamping, which has been monopolized by foreign enterprises in the domestic market, the bonding layer of gold and silver hot stamping foil and the thermoplastic part of the photosensitive film are hot-melt, and each blowtorch should be equipped with an accurate device to control the flow rate of propane and air to bond into one, which is not adhered to the thermosetting part, so as to realize the thermal transfer of the hot stamping film. Hot stamping equipment can be used for hot stamping with plastic sealing machine, electric iron and hot stamping machine. The temperature can be controlled between 100 and 130 degrees

5. Hot stamping finished products. After hot stamping, gently tear off the excess hot stamping film into a dazzling finished product in 12

II. Special hot stamping has the following advantages:

1. The hot stamping temperature is low, 100 to 130 degrees

2. Suitable for hot stamping of large areas and fine lines

3. It is suitable for the production of small batch and multi variety personalized hot stamping products

4. In the process of hot stamping, there is no need to make metal relief, which is low cost and fast. As long as there is a positive negative, hot stamping can be carried out

5. Hot stamping substrates are not limited, such as various plastic films, paper, leather, metal, glass, etc

6. Good adhesion to hot stamping substrate. After curing, the photosensitive film has the characteristics of high brightness, constant yellow and no scratch
