Hard Bound Book Printing are generally more used with convex
plate paper or offset paper as the book inside page.Most of the
written books use convex paper, such as fairy tales, fables,
and children's essays.The offset paper is mainly used for
printing higher color prints and is suitable for printing
children's books.Most of the cover material of picture
children's books is thick cardboard for framed copper paper,
because the awareness of child protection books is relatively
weak, the cover of thickened cardboard framed copper paper is
not easy to compromise, and the inner sheet rubber paper has
strong water resistance performance, which is easy to wipe and
clean when there is a small amount of stains. Influenced by
children's acceptance ability and learning ability, most
children's books hot sold in most bookstores are mainly picture
children's hard bound book printing.
