What is a seal? Explain to me exactly what it is!

Commonly referred to as "text printing" is the abbreviation of "text material printing". A large unit needs to print a lot of written materials a year. There are two ways: one is to ask others to print outside, and the other is to set up a "text printing room" to print by yourself. This is "text printing".

There is another one that is not "usually said", but archaeology. An antique has a thread. In order to study it, it is printed on paper like a stamp, and the result is the "text seal" of antiques.
