What is the hot stamping technology in carton packaging printing?

In the fierce market competition, in order to increase the added value of products and more effectively carry out packaging anti-counterfeiting, more and more carton packaging printing uses hot stamping technology. Hot stamping includes ordinary hot stamping, cold hot stamping, concave-convex hot stamping and holographic hot stamping. Commonly used ordinary hot stamping processes include flat flat hot stamping and round flat hot stamping. Because round flat hot stamping is line contact. It has a wide range of hot stamping substrates, suitable for large-area hot stamping, and high precision hot stamping. It is widely used.

Cold stamping does not need to use a heated metal plate, but uses a printing adhesive to transfer the metal foil. The cold stamping process has low cost, energy saving and high production efficiency. It is a promising new process.

Concave and convex hot stamping is the use of modern engraving technology to make up and down matching female and male molds. The hot stamping and embossing process is completed at one time, which improves production efficiency. The mold made by electric engraving can be curved to achieve the three-dimensional relief effect that is difficult to achieve with the mold made by the general corrosion method. The emergence of embossing and embossing enables the embossing and embossing processes to be completed at the same time, reducing the process and the waste caused by inaccurate overprinting.

The holographic mark adopts computer technology to change the amplitude and frequency of the grating, so that its effect is brighter and clearer than the color of the calculated pattern. If this kind of holographic mark is used as the original copy, a lot of holographic loss will be produced, so as to achieve the purpose of anti-counterfeiting. The holographic mark can not only have very good anti-counterfeiting performance, but also can make special numbers or characters into the holographic mark according to the needs of customers, and it is more and more widely used in high-end carton packaging.
