Whether the ink was thick or light was actually related to the style and use of the calligraphy work. In calligraphy, the thickness of the ink could be reflected by controlling the thickness of the strokes and the texture of the lines. The thick lines appeared thick and powerful, while the light lines appeared thin and soft. Therefore, thick ink was suitable for strong strokes and powerful lines, while light ink was suitable for soft strokes and delicate lines. In addition, the use of the calligraphy work would also affect the choice of ink concentration. For example, calligraphy works in an exhibition usually need to maintain a clear and readable visual effect, so light ink may be more suitable. In practical applications, such as writing Chinese characters in daily life, the ink density could be lighter to make it easier to read. Whether the ink was thick or light depended on the style and use of the calligraphy work, as well as personal preferences.
