1. Name stamps: Name stamps are generally divided into two types: Zhu Wen (Yang Wen) and Bai Wen (Yin Wen). When there are two name seals on a calligraphy work, it is best to have one in red and one in white, and the two chapters should be of appropriate size. When multiple chapters are used at the end of the payment, the order is the name seal first, then the word and number seals.
2. Introduction: It is generally not suitable to be square, but semi-circular, rectangular, circular, semicircular, gourd-shaped, natural shape, zodiac shape, etc. are better. Whether the initial seal should be stamped on the calligraphy work depends on the needs. If the initial seal is too neat, it needs to be "broken"; the final seal is too heavy and needs to be "upgraded"; the distribution of seals on the work is monotonous and needs to be "adjusted". This is An initial seal should be considered.
3. Pressed corner seal: The upper right corner is called "Yingshou", and the two lower corners are called "pressing corners". The border seal only covers one side; the corner seal covers both sides. Close to the corners, it plays the role of "blocking corners", "filling the void" and adjusting and stabilizing the picture.
4. Appraisal seal: The seal used for appraising the collection should be based on the size of the calligraphy and painting, and the main thing is not to damage the words and pictures. Some collectors, in order to preserve their reputation through the ages, often destroy the picture when stamping. This should be avoided.
Extended information:
Generally, seals are stained with pigment before printing. Those that do not stain with pigment and will appear concave and convex after being printed on a flat surface are called steel seals. Some are printed on wax or Wax seals on wax paint and envelopes. The production materials include metal, wood, stone, jade, etc.
The seal style of alternating red and white with text is very ingenious in Han seals, and it is said that it originated in the Eastern Han Dynasty. Its methods are extremely diverse, and the position arrangement and number of characters of Zhubai characters can be flexibly changed without limitation. This is evident from the number of prints cited here. The principle of Zhubai is roughly based on the number of strokes. Most Zhuwen has fewer strokes, while Baiwen has fewer strokes, so as to achieve the harmonious effect of Zhurubai, Bairuzhu. This type of seal is mostly a private seal with stable workmanship.
