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、紙伸開度

1. Paper stretch

如果開卷不合理，會增加卷邊材料，減少紙張的無效應用面積。短行較多的書，如橫排的詩集，用32開本，其瘦語及訂口有不少企業空缺，用紙使用較多。如果使用36頁的窄長形式，可以節約紙張。假如選擇開本設計過小，折數和光邊資料進行消耗也較多。為了方便印刷和包裝，盡可能或罕見地使用不規則成本，例如允許降低印刷和包裝的成本。

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、紙張資料

2. Paper data

紙張進行資料在圖書本錢中占領市場很大影響比重，約占40％以上。是以合理地選用紙張資料是下降圖書本錢的一個首要方面。

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.

統一類型的紙,克的重量,越高,注意紙的重量增加,書脊厚度也會增加,有時還需要調整封面紙的重量和開放的數字,這將發生一系列的關聯,往往增加紙的成本。

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.

當真選用不同紙張進行資料，但不克不及企業偷工減料，如用我們一般紙印較為復雜精致的網線版，會使整個版面依稀，造成浪擲。作為一般讀者可以選擇新聞紙，而且需要長時間保存的書不能使用易風化的新聞紙。

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、圖書頁數

3. Book pages

在拼組版時，要盡可能防止涌現零頁。由于一本書除正又外，另有一些其余重要部份如四封、扉頁、序、目次、頁等等，且大概就是每一個組成部份學生用紙分歧，把用紙范例進行溝通的紙的總面數湊成4的倍數關系其實不艱苦的。

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、裝訂方式與版式設想

4. Binding mode and layout assumption

常用的裝訂方法有騎裝、平裝、縫紉、裝訂等。騎馬訂、鎖線訂及膠訂這幾種進行裝訂工作方式，能夠把中間跨頁處版心設想得較小些。如果是平的，在版面中的跨頁會相對較大，因為平的書要占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.
