Hot stamping has ordinary hot stamping, cold stamping, bump hot stamping and holographic hot stamping. Commonly used ordinary hot stamping processes include flat-pressing hot stamping and round-pressing hot stamping. Due to the round-pressed hot stamping for line contact, it has the characteristics of hot stamping substrate, suitable for large-area hot stamping and high hot stamping accuracy. It is widely used in many gift packaging production.
Cold stamping does not require the use of a heated metal plate, but the transfer of the metal foil using a printed adhesive. The cold stamping process is a new process with low development cost due to low cost, energy saving and high production efficiency.
Bumping and hot stamping is the use of modern engraving technology to make the upper and lower die and male molds. The hot stamping and pressing process are completed at one time, which improves the production efficiency. The mold made by electric engraving can be curved to achieve a special three-dimensional relief effect. The appearance of bump hot stamping enables the hot stamping and pressing process to be completed at the same time, reducing the number of processes and scraps caused by inaccurate overprinting.
With a variety of manufacturing processes, the anti-counterfeiting performance of the holographic logo on many carton packs can play the most important role, the color is more brilliant, more clear, and the anti-counterfeiting is more precise.
