精裝書的特點(diǎn)，就在于封面通常質(zhì)地比較硬，表面裝幀講究、耐用，不易磨損。精裝書對保護(hù)書心的作用較強(qiáng)，封面應(yīng)略大于書心。下面濟(jì)南精裝書制作廠家來講講書籍的3大精裝方式。

The characteristics of hardcover books are that the cover is usually hard, the surface binding is exquisite, durable and not easy to wear. The hardcover book plays a strong role in protecting the book heart, and the cover should be slightly larger than the book heart. Next, Jinan hardcover book manufacturer will talk about the three hardcover methods of books.

書籍印后都需要裝訂，常見的裝訂方式有騎馬釘、膠裝等，但部分高檔書籍需精裝，這通常用于頁數(shù)較多、經(jīng)常使用、需長期保存、要求美觀和比較重要的圖書。它們的封面和封底要求用硬質(zhì)或半硬質(zhì)的材料。通常從外觀方面，書籍的精裝方式可分如下三種。

All books need to be bound after printing. Common binding methods include horse riding nails, rubber binding, etc., but some high-end books need to be hardbound, which is usually used for books with large pages, frequent use, long-term preservation, aesthetic requirements and more important books. Their cover and back cover require hard or semi-hard materials. Generally, from the aspect of appearance, the hardcover of books can be divided into the following three types.

圓背精裝

Round back hardback

圓背精裝是將精裝書封面之書背扒圓成圓弧形的裝訂形式。這種裝訂方式，可使整本書的書帖相互錯(cuò)開，便于翻閱，提高書芯的牢固程度。

Round-back hardcover is a binding form in which the back of the hardcover book cover is rounded into an arc shape. This binding method can make the book stickers of the whole book staggered, easy to read, and improve the firmness of the book block.

方背精裝

Square back hardback

方背精裝又稱平背精裝，與圓背精裝基本相似，區(qū)別僅在于書背沒有扒圓，呈平板狀。遇到將平裝改裝成精裝，或書頁都是單頁，則因無法穿線而只能做成平背。平裝改精裝多用于圖書館為保存購入的平裝書而為其加裝硬封面的情況。

The square back hardcover, also known as the flat back hardcover, is basically similar to the round back hardcover, but the difference is that the back of the book is not rounded and flat. If the paperback is converted to hardcover, or the pages are all single pages, they can only be made into flat backs because they cannot be threaded. The change from paperback to hardcover is mostly used in the case that the library adds a hard cover to the paperback book purchased for the purpose of preserving it.

軟面精裝

Soft finish

軟面精裝是為減輕書籍重量和方便翻閱，把硬面改為軟面，即用較薄的紙板代替一般精裝書上較厚的紙板，一般較厚和經(jīng)常翻閱的書籍，譬如各種工具書，多用此法裝訂。

In order to reduce the weight of books and make them easy to read, the hard side is changed to the soft side, that is, the thinner cardboard is used to replace the thicker cardboard on the general hardcover books. Generally, the thicker and frequently read books, such as various reference books, are bound in this way.
