It can be done before tempering or after tempering. If it is before tempering, it is usually silk-screened with glaze that is difficult to remove.

However, the toughened label is the kind of label mentioned by the landlord, but this label is not printed by itself and must be purchased in CNCA.

The minimum package can also be marked, and the mark must also be filed with CNCA by the manufacturer and reviewed once a year.

If someone says that the product is unqualified only because the glass surface was not silk-screened or toughened before labeling.

This is illegal. This is stipulated by law.

Please don't talk nonsense to avoid misleading.

There is also a customer's request. This is necessary if the customer must screen print on the glass surface.

If the customer doesn't ask for it, what kind to use and the identification method will be decided by the manufacturer!

Of course, there are many details, such as records, process methods and so on. I won't elaborate here.
