According to the processing method of the self-adhesive label, the hot stamping method is divided into single sheet hot stamping and roll paper hot stamping. Sheet paper hot stamping is the same as the traditional hot stamping process, which is processed on a dedicated hot stamping machine. Roll paper bronzing is done on the label linkage, which is the most widely used processing method.
There are several ways to bronzing roll materials:
1.Flat stamping and hot stamping on the labeling machine
2.Multi-station flat pressing and hot stamping
3.Flat stamping and bronzing on the processing machine
4.Round pressing and hot stamping on the rotary machine
5.Cold hot stamping on the rotary machine
This is a new hot stamping process. The heated metal printing plate is no longer used, but the method of printing adhesive is used to transfer the metal foil to achieve hot stamping. The process flow is: UV pressure-sensitive adhesive is printed on the position where the printed product needs hot stamping, the adhesive is dried by a UV drying device, and then the special metal foil is combined with the pressure-sensitive adhesive, and then the metal foil is peeled off. The part of the foil that needs to be transferred is transferred to the surface of the printed matter to achieve cold hot stamping. The cold stamping process has low cost, saves energy, and has high production efficiency. It can use existing equipment components without adding additional devices. It is a promising new process.
