精装书与平装书的主要区别，不但在于封面材料不同，而且还在于装帧加工中要对书心和封面进行造型加工。
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、书心的造型主要选择采用以下加工方法
1、 The following processing methods are mainly selected for the modeling of the book center
1.圆背加工
1. Round back processing
这是对书心的书背进行变形加工，使之呈现一定弧度。圆脊又分“有脊”和“无脊”两种类型。书脊突出书面的称“有脊”，不突出书面的称“无脊”。有脊的图书更为美观大方切容易翻阅。
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.圆角加工
2. Fillet machining
这是对书心处于书口部位的两个书角进行加工，使之呈现圆弧状。不做圆角加工的书角称为“方角”。书心无论是圆脊还是方背，都可以采用方角或圆角的造型。
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.堵头布选用
3. Selection of plug cloth
在圆背和较厚的方背图书上，还可以用不同的堵头布来装饰书心。
On round back and thick square back books, different plug cloth can also be used to decorate the book center.
二、书壳造型
2、 Book case modeling
1.包角
1. Wrap angle
包角是在书壳的四个角上或仅面封的两个角上包一层皮革或织物。它一般适用于纸面书壳。在图书使用过程中，处于书角部位的纸张收到摩擦比其它部位更多，而纸张耐磨性较差，包角可以延长书壳的使用寿命。
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.圆角加工
2. Fillet machining
这是对书壳的书角进行加工使之呈圆弧状。如果书心已经做圆角加工，那么书壳也宜相应地进行圆角加工；也有书心不做圆角加工而仅书壳做圆角加工的。圆角书壳的制作比较费工，但牢靠性较好。
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.
