BACKGROUND
1. Technical Field
The present disclosure generally relates to spraying and printing devices, and particularly to a spraying and printing device capable of spraying various dyes continuously.
2. Description of Related Art
Commonly used spraying and printing devices may be only capable of spraying one dye, thus, when a soft substrate such as an electronic paper needs to be spayed and printed with various dyes, the soft substrate needs to be transferred from one spraying and printing device to another spraying and printing device. The transferring process may be time-consuming, and the spraying effect may not good.
Therefore, there is room for improvement within the art.
