Label hot stamping process sharing of self-adhesive printing manufacturers
Now the self-adhesive label is a very common material in life. Some self-adhesive labels will use the bronzing process. The bronzing process is divided into first bronzing and post bronzing. Different process methods show different characteristics. In order to make our label printing look good, or if the quality is good, it is very important to understand the specific method of the hot stamping process. If the quality of the products wholesaled by the sticker printing factory does not pass the test, it will be eliminated by the market, so as a qualified sticker For printing manufacturers, the effect of our company’s bronzing process is still very good, and all kinds of product packaging labels are available.
1, first bronzing process
When the label machine with intermittent paper hot stamping components installed in front uses ordinary ink to print labels, the first hot stamping process is adopted. Since the ink used is oxidative polymerization drying type, it takes some time for the ink layer to dry after printing, so hot stamping The pattern needs to avoid the ink. The recommended way to avoid ink is to pre-stamp the web material before printing. The use of the first bronzing process requires that the printing pattern and the bronzing pattern are separated, because the surface of the anodized aluminum is smooth, no ink, and cannot be printed. Self-adhesive printing manufacturers said that hot stamping can prevent the ink from smearing and ensure the quality of label printing.
2, post bronzing process
Post bronzing process is applied to the labeling machine where the bronzing parts are installed on the back door, and UV ink is used for printing. Since the ink has been dried, the bronzing pattern and the printing pattern can be side by side or superimposed, and the ink smear phenomenon will not occur. Of the two bronzing methods, post bronzing is the ideal method, which also brings convenience to label pattern design and expands the application range of bronzing patterns. However, due to the limitations of equipment functions, the cost of label printing is relatively high. The first bronzing process is suitable for the processing of small labels with simple patterns, with low cost and wide application range. It is a commonly used method in small and medium-sized printing plants.
