The production of every paper book will have two main processes: printing and binding. Then we have to distinguish between hardcover and paperback. First of all, the printing process is the same, but the importance of color management in Huangyan Huifeng applies to all books and periodicals. Whether it is a hardcover book or a paperback book. The difference between the two lies in the different binding methods. The binding methods of hardcover books are complicated, but the products are more refined, which makes the functionality of the books biased towards collection. But the role of the paperback book is more emphasis on the current use, only to meet the general needs.
The paper used in Huangyan Huifeng's production of books and periodicals is selected according to the prescribed number of grams. The paper and printing process of hardcover and softcover books are required by the unified standard. However, in the subsequent process, the hardcover books will be at least 5-10 more than the softcover books. Crafts, such as gold edge grinding, bronzing, painting, plugging cloth, sticking ribbon. Therefore, as the process increases, the use of auxiliary materials will also increase.
So in terms of cost, hardcover books will be higher than paperback books. Paperback books are books that we usually use. For example, textbooks, glue binding technology is generally used, that is, the inner pages of the book are glued together with special binding glue, and then glued together with the cover. Use a special perfect binding machine. The cover is ordinary coated paper or something, which is thicker than the inner pages. The whole book can be bent and held in your hand.
The craft consultant of Huangyan Huifeng Company told the editor that the inner pages of hardcover books generally use a thread-locking process, which means that the inner pages are locked together with threads and glued, so that they are stronger and do not like falling pages. The cover is generally a gray board with a thickness of 1MM-2MM. Paste the finely printed thin paper on the gray board to form a book case, and then glue the backing paper on the book case. Hardcover books cannot be bent. They can be spread out at 180 degrees and appear high-grade. Generally, they are thick and beautiful due to the hard cover.
The difference between hardcover books and paperback books is mainly based on the binding method and material selection requirements. If someone tells you that the paperback books can allow the printing color difference to be larger than that of the hardcover books, this is a wrong analysis.
In Hungyan Huifeng, you can know that regardless of whether the hardcover book or the softcover book, the printing requirements must pass the FROGA39 test to confirm the color, and to ensure that the printed product minimizes the color difference. Therefore, the real distinction between hardcover and softcover books is the binding process. The difference.
