Pasting wall tiles is an effective way to protect the wall surface from water splashing. They are not only used on the wall, but also used on the edge decoration of doors and windows, which is also an interesting decorative element. It can be used for decorative wall tiles at the skirting line, which is not only beautiful but also protects the wall base from being stained by shoes or table and chair legs. It can also be used for tiles in sinks and bathrooms, which requires beauty, moisture resistance and wear resistance.
[0003] With the increasing improvement of living standards, the aesthetic level of current consumers has also improved. The requirements for the decoration effect brought by the previous wall tiles are increasingly strict. Unlike in the past, the general consumers have begun to experience aesthetic fatigue from the decorative effect brought by the close arrangement of multiple repeated tiles on the wall. They have begun to use similar murals for decorative walls. However, murals have a large area, and if the content of the mural is composed of multiple tiles, the gap between the tiles will affect the visual perception of the mural content. Therefore, manufacturers have begun to print the content of the mural on a large wall tile to eliminate the impact of the gap between the tiles on the mural content. However, the printing requirements are very high, and it brings inconvenience to the transportation of the wall tiles, increases the transportation cost of the wall tiles, and the thickness of the printed coating is low, which is easy to fall off when encountering external bumps, affecting the visual perception of the mural. Therefore, it is necessary to propose a new scheme to solve the above problems. SUMMARY
