In the fierce market competition, in order to increase the added value of the product and more effectively carry out packaging anti-counterfeiting, more and more packaging cartons adopt hot stamping process. Hot stamping includes common hot stamping, cold hot stamping, bump hot stamping and holographic hot stamping. Common common hot stamping processes are flat flat hot stamping and round flat hot stamping. Because round flat hot stamping is line contact. The printing base material is factory wide, suitable for large-area hot stamping, and has high hot stamping precision. It is widely used.
Cold hot stamping does not require the use of heated metal plates, but transfers the metal foil using printing adhesives. The cold stamping process has a low cost, saves energy, and has high production efficiency. It is a promising new process.
Concavo-convex hot stamping (also known as three-dimensional hot stamping) is the use of modern engraving technology to make the upper and lower female and male molds. The hot stamping and pressing and bumping processes are completed at one time, which improves the production efficiency. The mold made by electric engraving can be curved surface transition to achieve the three-dimensional relief effect of the mold made by the general corrosion method. The appearance of uneven hot stamping makes the hot stamping and embossing processes complete at the same time, reducing the process and waste products caused by inaccurate overprinting.
The holographic logo uses computer technology to change the amplitude and frequency of the grating to make its effect more brilliant and clearer than the calculated color of the pattern. If this kind of holographic mark is used as a copy of the original, a large amount of holographic loss will occur, so as to achieve the purpose of anti-counterfeiting. The holographic logo can not only have very good anti-counterfeiting performance, but also can make special numbers or words in the holographic logo according to the needs of customers.
