Are there any special technologies or patents for ceramic tiles?

There are basically no patents at present. All patents are basically aimed at appearance or packaging, and there are basically no patents that really belong to the technical category.

Nowadays, the weight and firing temperature of the press are generally tested for ceramic tiles, and the technology is generally reflected in printing. 3D inkjet should be a relatively good technology recently applied, which greatly improves the authenticity and clarity of patterns.

Other basic looks, it doesn't matter
