Books are made up of several pages. When printing, single pages must be assembled into large pages as required, and then folded into books. This requires typography based on printing and binding methods.
First, put version
According to the book's page order, combined with the specific requirements of the printing and binding methods, the process of rationally arranging, combining printing plates, and arranging the positions of the printing plates is called tiling. The general typography method includes two methods, a typographic version and a typographic version. Reversal is the use of a printing plate to print on the front side of a sheet. When it is printed on the desired number of copies, the printed page is turned over, not changed, and printed on the reverse side of the printed page. Using this typography method, after printing, it is necessary to cut it from the middle and fold it with a folding-folding machine. Copy-making is the use of half of the entire printing plate, printing on the front side of the paper, and then printing the other half of the printing plate on the reverse side of the paper. Larger books use this method. Figure 2-18 shows the two methods of tiling.
Second, the relation between swing version and binding method
In the process of typography, according to the folding, stapling, and cutting techniques used during the binding process, the typography work must be carried out correctly so that the printed pages can be folded easily, the number of cuttings is small, and the matching, stapling, etc. Process requirements.
1. The relation between the swing version and the folding method. The folding of the pages is mainly accomplished using a folding machine. The folding method of the signature determines the combination of the printing plate and the arrangement of the printing plate. The arrangement of printing plates is different, and the folding style also changes. The layout of the printing plate layout must be determined according to the processing method of the folding sheet. For example, when a certain type of folding machine is used to fold a page, the arrangement mode of the printing plate has to be arranged in accordance with the operation law of a folding mechanism. If it is changed to manual folding, it is inconvenient, so the tumbleplate must be adapted to the folding. method.

The folding methods and methods of the special folding devices that are currently used for folding machines and web-fed rotary printing machines have been described in the relevant parts of the first, second, third and fourth sections of this chapter. No longer rumors.
