1. In the self-adhesive labeling machine to complete flat stamping
No matter whether the gravure self-adhesive printing machine is flat or round press flat type machine equipment, because the roll paper is basically intermittent feeding, so stamping all choose flat press square type. Generally speaking, the stamping process is an independent unit, and some models share a unit to cut the foil and apply it separately.
2. Multi position flat stamping
Some models have two working positions of stamping unit, one of which is close to the printing plate to complete horizontal stamping, and the other is an independent unit to complete vertical stamping. The machine can complete two-color stamping at the same time.
3. Rotary machine on the round hot stamping
The bronzing plate used in the rotary hot stamping is in the shape of a roller. When the bronzing plate is in contact with the press roller, the bronzing is completed. Circular hot stamping is more suitable for continuous paper feeding rotary label machine application, but there is a corresponding demand for paper feeding speed, in other words, it has an impact on the printing speed. But relatively speaking, in the flat stamping, further improve the work efficiency. The manufacturing cost of the roll is high, so it is only suitable for long version live stamping.
4. Cold stamping on rotary press
This is a new stamping process. Instead of using the heated metal material printing plate, we use the printing adhesive to transfer the metal material foil and complete the stamping. Cold stamping process has the advantages of low cost, energy saving and high production efficiency. It can use the current machine and equipment parts without additional devices. It is a new process with a bright future.
