Every book needs to be seen as a whole by the author. The designer must make assumptions according to the teaching content, nature, total amount of pictures and texts and reader management tools. The high cost of books is the primary factor in book market cooperation. From the perspective of prepress assumption, we now talk about how to reduce the cost of books.

1、纸伸开度

1. Paper stretch

如果开卷不合理，会增加卷边材料，减少纸张的无效应用面积。短行较多的书，如横排的诗集，用32开本，其瘦语及订口有不少企业空缺，用纸使用较多。如果使用36页的窄长形式，可以节约纸张。假如选择开本设计过小，折数和光边资料进行消耗也较多。为了方便印刷和包装，尽可能或罕见地使用不规则成本，例如允许降低印刷和包装的成本。

If uncoiling is unreasonable, it will increase the crimping material and reduce the invalid application area of the paper. Books with more short lines, such as horizontal poetry collections, are in 32 format. There are many enterprise vacancies in their thin language and binding mouth, and they use more paper. If you use the narrow and long form of 36 pages, you can save paper. If the format design is too small, the consumption of folding and light edge data is also more. In order to facilitate printing and packaging, irregular costs are used as rarely as possible, for example, allowing the cost of printing and packaging to be reduced.

2、纸张资料

2. Paper data

纸张进行资料在图书本钱中占领市场很大影响比重，约占40％以上。是以合理地选用纸张资料是下降图书本钱的一个首要方面。

Paper materials occupy a large market share in book costs, accounting for more than 40%. Therefore, the rational selection of paper materials is a primary aspect of reducing the cost of books.

统一类型的纸,克的重量,越高,注意纸的重量增加,书脊厚度也会增加,有时还需要调整封面纸的重量和开放的数字,这将发生一系列的关联,往往增加纸的成本。

The higher the weight of the same type of paper, the higher the price. Pay attention to the increase of the weight of the paper, and the thickness of the spine will also increase. Sometimes it is necessary to adjust the weight of the cover paper and the open number, which will have a series of associations, often increasing the cost of the paper.

当真选用不同纸张进行资料，但不克不及企业偷工减料，如用我们一般纸印较为复杂精致的网线版，会使整个版面依稀，造成浪掷。作为一般读者可以选择新闻纸，而且需要长时间保存的书不能使用易风化的新闻纸。

If you really choose different paper for data, but you can't cut corners. If you use our general paper to print a more complex and exquisite screen version, the whole layout will be blurred and cause waves. As a general reader, you can choose newsprint, and books that need to be preserved for a long time cannot use perishable newsprint.

3、图书页数

3. Book pages

在拼组版时，要尽可能防止涌现零页。由于一本书除正又外，另有一些其余重要部份如四封、扉页、序、目次、页等等，且大概就是每一个组成部份学生用纸分歧，把用纸范例进行沟通的纸的总面数凑成4的倍数关系其实不艰苦的。

When assembling the version, try to prevent the emergence of zero pages. Because a book has some other important parts besides the right one, such as four seals, title page, preface, contents, copyright page, etc., and it is probably the difference between students in each component, it is not difficult to round up the total number of pages of paper used for communication into a multiple of 4.

4、装订方式与版式设想

4. Binding mode and layout assumption

常用的装订方法有骑装、平装、缝纫、装订等。骑马订、锁线订及胶订这几种进行装订工作方式，能够把中间跨页处版心设想得较小些。如果是平的，在版面中的跨页会相对较大，因为平的书要占5mm。

The commonly used binding methods include riding, paperback, sewing, binding, etc. Horse riding binding, sewing and adhesive binding can make the layout center of the middle cross page smaller. If it is flat, the page spread in the layout will be relatively large, because the flat book takes up 5mm.
