Description

[0002] Cold stamping technology refers to a method for transferring a stamping foil to a printing material by using a UV adhesive. The cold stamping process can be divided into dry film cold stamping and wet film cold stamping, and the cold stamping technology provides a new opportunity for printing enterprises, and the biggest advantage is that it requires little investment, and even no investment at all. Another outstanding advantage is that it has a high cost performance, which is the biggest selling point of the cold stamping technology. In the process of cold stamping, semi-automatic equipment needs manual feeding, and full-automatic equipment needs to use a feeding roller to feed the raw material. In the feeding process, the raw material is usually placed vertically.
