The advantages and production process of special hot stamping process
In order to continuously improve the exquisiteness and value of the printed matter, the special bronzing process was born, and the hot stamping process was divided into two camps: traditional hot stamping process and special hot stamping process. Today, I will introduce to you the advantages and production process of special bronzing process. There are differences between special hot stamping and traditional hot stamping 1. There is no need to make metal letterpress in the hot stamping process, the cost is low, the speed is fast, and as long as there is a positive picture negative, it can be hot stamped. 2. It is suitable for the production of small-batch and multi-variety personalized hot stamping products. 3. The hot stamping temperature is low, 100 to 130 degrees. 4. It is suitable for hot stamping of large area and fine line graphics. 5. Hot stamping substrates are not subject to processing, 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, no yellowing, and no scratches. Specific hot stamping process Printing or spraying printing photosensitive hot stamping ink → dry → film exposure → hot stamping → finished product. 1. Use 200-300 mesh screen full plate brush photosensitive ink or spray the substrate to be hot stamped evenly with a spray gun. Liquid photosensitive ink is a transparent varnish that is specially used for all kinds of hot stamping. It has excellent light sensitivity and a high graphic resolution with a minimum line width of 0.05 mm. 2. Drying. Dry with blowing air or use a screen oven to dry, pay attention to the temperature at about 40 degrees. 3. Film exposure. Use the computer to design and produce the required hot stamping graphics and texts, and output the negative for ultraviolet exposure. After UV exposure, the non-patterned part of the film becomes thermoset, and the patterned part remains thermoplastic. 4. Hot stamping. In the hot stamping process, the gold and silver hot stamping foil adhesive layer and the thermoplastic part of the photosensitive film are bonded together due to hot melting, and do not adhere to the thermosetting part, so as to realize the thermal transfer of the hot stamping film. The hot stamping equipment can be used for hot stamping with plastic sealing machine, electric ironing iron and hot stamping machine. The temperature can be controlled at 100 to 130 degrees. 5. Hot stamping of finished products. After hot stamping, the excess hot stamping film is gently torn off into a brilliant finished product.
