2. Description of the Related Art FIG. 9 shows an example of a conventional rotary press for newspaper printing. In the rotary press, the printing unit 1 performs predetermined printing on the web 2 drawn out from the paper feeding unit A, and the webs 2 double-sided printed by the three printing units 1 are sent to the folding unit B in an overlapping state. After being cut and folded at the folding portion B to form a newspaper, the newspaper is sequentially discharged onto a conveying device (not shown) via a delivery fan C and the like.

For example, when a so-called A-paper roll 2 is used and the single-sided printing is performed, each printing unit 1 can print eight newspaper pages, and in the case of FIG. 9, a 24-page newspaper is printed. Will be. Similarly, in the printing machine of FIG. 9, when printing is performed on both sides, 4 pages of newspapers are printed in each printing unit 1,
A total of 12 pages of newspapers will be printed, and the number of contacts of the printing unit 1 will change according to the number of pages in the newspaper.

[0004] By the way, in newspaper printing, a newspaper having a local edition or a regional edition, which is called a zoning news paper, has been conventionally printed. The printing of these zoning news papers is usually performed by printing the required number of newspapers having the area A area paper, and then stopping the operation of the rotary press to correspond to the area A area paper surface of the printing unit 1. The printing plate is removed and replaced with a printing plate for the B area version, and then the rotary printing machine is restarted so that a predetermined number of newspapers having the B area version are printed.

However, it takes 2-3 minutes at the earliest to stop the rotary printing press during high-speed operation, and it takes 2-3 minutes from the stopped state to the high-speed operation state. I need. Further, since it takes 2 to 3 minutes to replace the printing plate, it requires about 6 to 7 minutes to replace the printing plate, resulting in a significant decrease in printing efficiency. There is. Further, not only the number of workers required to replace the printing plate increases, but in the case of an offset printing machine, a large number of waste papers are generated at the time of restart from the viewpoint of the balance between the water content of the printing section and the ink components. Therefore, there is a problem that it is difficult to reduce the printing cost.

On the other hand, in recent commercial newspapers, in addition to the conventional zoning news paper, newspapers having a paper surface according to the hobby of the reader and the class of readers such as general readers and station readers (that is, the reader's Newspapers / Tillard Newspapers that have pages suitable for selection, and newspapers that have advertising pages according to the hobby and economic power of readers, and the number of readers such as general readers and station readers (that is, advertiser selection) The demand for newspapers / targeted news papers, etc. that have corresponding advertising pages is rapidly increasing. However, similar to the conventional newspaper printing method, in the printing method in which the rotary printing press is temporarily stopped, the printing plate of the printing unit is replaced and then restarted, the printing efficiency is remarkably reduced as described above. It becomes extremely difficult to print a newspaper having a predetermined number of different paper surfaces within a given printing time, and there is a problem that it is not possible to sufficiently respond to the request for issuance of the Tillard news paper or the targeted news paper. is there.

[0007]

SUMMARY OF THE INVENTION The present invention has the above-described problems in the conventional printing of zoning news paper, that is, it takes time to start and stop the rotary printing press and replace the printing plate. It is intended to solve the problem that it becomes difficult to print a newspaper having a predetermined number of different paper surfaces due to the reduction of the substantial operating time of a printing device unit (printing couple) forming a printing unit.
The present invention provides a newspaper printing method capable of continuously printing a predetermined number of newspapers having different paper surfaces without stopping the rotary printing machine, although the cardinal number of (1) is slightly increased.

[0008]

For example, in the case of printing of zoning news paper, a common printing plate is attached to the first printing device unit that forms the printing section, which is common to each region required for forming the newspaper surface, and the second printing The printing plate required for forming the paper for the area A in the device unit, and the printing plate B in the third printing device unit
Install the printing plates required for forming the regional paper.
Next, the first printing device unit and the second printing device unit are operated to print the required number of copies of the newspaper for the area A, and then the operation of the second printing device unit and the third printing device unit is switched to the area B.
