Background technique

Painting refers to the practice of adding color on a surface as a support surface on a technical level. Those surfaces can be paper or cloth. The tools for adding color can be brushes, brushes, or sponges. It is cloth strips, etc., and software can also be used for painting, while fine art paintings are flat or three-dimensional plastic art works composed of paintings;

Usually when drawing art works, you need to use pigments, and most of the pigments are mixed with water to draw on paper. Often the pigments are still wet after drawing, and they need to wait for the pigments to dry before they can be preserved. Traditional The best drying method is natural air drying, which takes a long time and is inefficient. The wind provided by natural air drying is irregular and poor in stability, so that the paper cannot be evenly exposed to the wind, and it is easy to cause the pigment on the paper to not dry completely, and it will be damaged.
