精裝書與平裝書的主要區別，不但在于封面材料不同，而且還在于裝幀加工中要對書心和封面進行造型加工。
The main difference between hardcover books and paperback books lies not only in the different cover materials, but also in the modeling processing of the book center and cover in the binding processing.
一、書心的造型主要選擇采用以下加工方法
1、 The following processing methods are mainly selected for the modeling of the book center
1.圓背加工
1. Round back processing
這是對書心的書背進行變形加工，使之呈現一定弧度。圓脊又分“有脊”和“無脊”兩種類型。書脊突出書面的稱“有脊”，不突出書面的稱“無脊”。有脊的圖書更為美觀大方切容易翻閱。
This is to deform the back of the book center to make it present a certain radian. Round ridge can be divided into two types: "with ridge" and "without ridge". If the spine is prominent in writing, it is called "ridge", and if it is not prominent in writing, it is called "no ridge". Books with ridges are more beautiful and easy to read.
2.圓角加工
2. Fillet machining
這是對書心處于書口部位的兩個書角進行加工，使之呈現圓弧狀。不做圓角加工的書角稱為“方角”。書心無論是圓脊還是方背，都可以采用方角或圓角的造型。
This is to process the two corners of the book center at the mouth of the book to make it arc-shaped. Book corners without fillet processing are called "square corners". The book center, whether round ridge or square back, can be shaped with square corners or rounded corners.
3.堵頭布選用
3. Selection of plug cloth
在圓背和較厚的方背圖書上，還可以用不同的堵頭布來裝飾書心。
On round back and thick square back books, different plug cloth can also be used to decorate the book center.
二、書殼造型
2、 Book case modeling
1.包角
1. Wrap angle
包角是在書殼的四個角上或僅面封的兩個角上包一層皮革或織物。它一般適用于紙面書殼。在圖書使用過程中，處于書角部位的紙張收到摩擦比其它部位更多，而紙張耐磨性較差，包角可以延長書殼的使用壽命。
Corner wrapping is to wrap a layer of leather or fabric on the four corners of the book case or only the two corners of the face seal. It is generally suitable for paper book cases. In the process of using books, the paper at the corner of the book receives more friction than other parts, and the wear resistance of the paper is poor. The corner can prolong the service life of the book case.
2.圓角加工
2. Fillet machining
這是對書殼的書角進行加工使之呈圓弧狀。如果書心已經做圓角加工，那么書殼也宜相應地進行圓角加工；也有書心不做圓角加工而僅書殼做圓角加工的。圓角書殼的制作比較費工，但牢靠性較好。
This is to process the corners of the book case to make it arc-shaped. If the book center has been rounded, the book case should also be rounded accordingly; There are also book centers that do not do fillet processing, but only book cases that do fillet processing. The production of rounded book case is laborious, but it is reliable.
