No more than three seals may be used for name seals on calligraphy and painting. Two seals should be used, or one seal is appropriate. When sealing two seals, the upper yin and lower yang must match.
Stamping methods: 1. Fill in the gaps: There are too many holes in the painting. A small red seal can fill in the so-called "empties". 2. Entraining Qi: The picture is composed of Qi or momentum from all directions. If you feel that the momentum in a certain direction is not enough, you can choose a "golden point" to stamp it, so that the momentum can be supplemented. 3. Balance the picture: After the entire painting is finished, if you feel that the color or pen and ink in a certain position are too "heavy", you can stamp a seal at the corresponding position to balance it. 4. Coordinate the picture frame: Generally, the name seals used have two parts, yin and yang (name, character or number, etc.), which are stamped at the signature at the same time. This sometimes makes the red color appear too concentrated. It is often necessary to choose a position to stamp with the "pressure corner" and "rise". "First", "Welt", etc. to coordinate.
Yangwen seal: The effect of the Yangwen seal is that the text is red and the blank is white. Yinwen seal: The effect of the Yinwen seal is red on the bottom and white on the text. Yin seals are mostly white in color; Yin and Yang seals refer to Yin seals and Yang seals. Seal characters or images have two shapes: concave and convex. The concave seals are called Yin seals, and the raised seals are called Yang seals.
