According to the situation of white cloth, the signature is a square of 1~2, and the square is a positive body. If one side is used for printing, select a white name for printing; If it is printed by two parties, in addition to the white surname, one party's Zhu Wenming or other seals are added. The size of the printed surface is similar to or slightly smaller than the inscription, preferably not larger than the inscription, and there is at least one printing distance between the two sides.
In addition, on the right side of the first word of a calligraphy work, an introduction stamp can be used, which can be rectangular, oval or arbitrary in shape, and the content is not limited. Generally, they are mostly auspicious words or aphorisms, and both Zhu Wen and Bai Wen can do it. The position of the seal should not be flush with the first word of the work, nor should it be flush or staggered with the end of the first word. If the calligraphy works are large in format, they are also stamped at the middle waist, but this is rare.
As for the appreciation seal, it belongs to the appreciation collector and has nothing to do with the calligraphy author's own seal, nor is it an organic part of the work itself.
