About calligraphy seal

The principle of stamping is generally not larger than the signed words, but smaller but not larger, and it is indecent to print too big. Generally, a work can't be printed too much, leaving enough space to make the work "breathable". The seal is an ornament, and it cannot usurp the role of the master. It should be smaller and smaller. The place where the seal is affixed is that the introduction chapter is affixed to the top of the work, and the first and second words of the text should not be too far away from the first line of the text of the work, just leaving the grid (or overlapping lines). The name seal is stamped with one or a pair directly below the signature; Or the inscription uses a pair of left covers, that is, one cover is on the left side of the lower position in the middle of the inscription, and the other cover is on the lower left of the last word. You can also use two seals to press half a line at the same time, but the seal should be exposed more than half (the left side of the inscription). Mainly arranged according to the overall needs of the work. Cover with a pair of seals of basically the same size. In addition, the distance between two seals, one for Yin (white characters on red background) and the other for Yang (scarlet letters on white background), should not be less than the diameter of the seal. If printed on the bottom of the seal, the distance between Yin and the last word of the seal should not be greater than the diameter of the seal. Moreover, the seal used in calligraphy must be seal script, not the seal that imitates modern Song Dynasty. This is just a general situation, and sometimes it can be handled flexibly according to the situation. As for the leisure stamp (that is, the general small seal, the content is a poem, idiom, phrase, or other small shapes), it should be used less and smaller. If used well, it will be the finishing touch. If you don't use it well, the whole work will be broken. How to use it is quite flexible, and we should think it over and over again according to the situation. You didn't ask about the classification of seals. I think it has been said before, so I won't say much. Is it okay to explain this?
