April 07, 2022

Ceramic decal paper refers to the application of ceramic decal paper on the surface of ceramics (or porcelain blank), which can be divided into underglaze, in glaze, overglaze, primary firing and secondary firing. Underglaze color and underglaze color will never change color, and overglaze color can remain unchanged for more than ten years. Some handicraft ceramics (such as home decoration, etc.) Use non baked ink decals. So, what are the characteristics of printed ceramic decals?
