Paperback is important for a book. A proper paper back is usually printed with the relevant series of the book, recommending comments from some famous critics, or pictures related to the theme. Many readers judge a book's quality by referring to paperback, so we use both-sides coated art paper and gloss art paper for paperback printing. And UV coating, gloss lamination and full-color printing and embossing are available so to make the paperback looks more professional and eye-catching.
