The hot stamping of the self-adhesive is also divided into the first hot stamping and the post-hot stamping. The first hot stamping refers to first stamping on the labeling machine and then printing; then the hot stamping refers to printing first, and finally bronzing. The key to hot stamping and post-hot stamping is the drying problem of the ink. There are two situations in the relationship between bronzing patterns and printed patterns: juxtaposition and overprinting. Due to the different inks used, the label printing must be carried out by two processes: first hot stamping and post hot stamping.


First hot stamping process

When the labeling machine with the intermittent paper feeding unit is used to print the label with ordinary ink, the first hot stamping process is adopted. Since the ink used is an oxidative polymerization drying type, it takes a certain time for the printed ink layer to dry completely, so bronzing The pattern must avoid the ink. The best way to avoid ink is to pre-warm the roll material and then print it.

The use of the first bronzing process requires that the printed pattern and the bronzing pattern be separated (parallel) because the surface of the anodized aluminum is smooth, not inked, and cannot be printed. The first hot stamping prevents the ink from being dirty and ensures the quality of the label printing.


Post bronzing process

The post-hot stamping process is applied to the labeling machine where the hot stamping parts are mounted on the back door, and UV ink is used for printing. The web material is first printed and the ink is dried instantaneously by a UV drying device and then bronted on the surface of the material after drying or on the surface of the ink. Since the ink is dry, the bronzing pattern and the printed pattern can be juxtaposed or overprinted without ink smudging.
