However, the printing method of the display layer (A3) using ink is only suitable for flat or slightly curved decorative plates. When the decorative plate is of a large curved surface type, the display layer (A3) using ink printing has the following problems:

1. When screen printing is used, curved surface printing, such as printing on the concave surface, will cause the problem of incomplete transfer of the graphics and the formation of missing parts. Therefore, if the curvature radius of the concave surface is too large or there are special shapes, the screen cannot be used. print.

2. When using pad printing, curved surface printing may sometimes produce burrs at the border of the graphics or problems such as broken graphics, resulting in poor graphics appearance.

3. When hot stamping is used, when printing on curved surfaces, it is easy to cause burrs on the borders of graphics or poor appearance in printing. At the same time, hot stamping makes the substrate need to undergo a high temperature and high pressure process, which is easy to cause stress and cracking on the curved substrate.
