The printed version refers to the genuine version. First of all, the seal is the author. He signed the book and his novel, and then the businessman took it to make copies. If the author has no authorization, he will not sign the novel, so there will be no printing. So if it is printed, it must be genuine, because it is best not to forge the author's.

The characteristics of genuine:

There will be a silky but not rough feeling. Because genuine books are printed uniformly after authorization, the pulp used is not so bad, while pirated books are simply printed.

Therefore, in contrast, genuine books will be much smoother and feel less rough, and pirated books will save costs, so the raw materials used are very general. Of course, some books are not so silky to the touch.
