Rotating wheel printing 64-book-size book body text four-connected makeup perfect binding method

Abstract

The invention discloses a rotating wheel printing 64-book-size book body text four-connected makeup perfect binding method. Firstly, according to the 16-book-size section makeup, the breadth is evenlydivided into four parts, contents on the upper and the lower on the left side are subjected to two-connected makeup operation, contents on the upper and the lower on the right side are subjected to inserted two-connected makeup operation, a made printing plate is printed on a rotating wheel printing machine, printing and page folding work of the 16-book-size book body text four-connected sectionis finished, according to the page sequence, bookblock association is finished, the upper and the lower of one half of the left side of the bookblock are subjected to two-connected operation, the leftside of the bookblock serves as a spine, milling slot broaching coating pasting of the cover is carried out, the right rough selvedge on the bookblock is cut off, the right side of the bookblock serves as the spine, and groove broaching coating pasting of the other half two-connected cover can be achieved; according to the transverse center line and the longitudinal centre line, slitting is carried out, redundant paper sides are cut off, and four 64-book-size book finished products are obtained; and the advantage of the rotating wheel printing machine are fully exerted, the 64-book-size section four-connected book are subjected to perfect binding two times, the perfect binding efficiency is improved by more than two times compared with a traditional 64-book-size single perfect binding, and the printing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a printing and binding method for books, in particular to a method for rotary printing 64-format books with four impositions of four impositions. Background technique [0002] In the book printing industry, a piece of flat base paper cut according to national standards is usually called full-open paper; Several small sheets of paper are called the number of folios; binding these small papers into a book is called the number of folios. In other words, the format refers to the size of the format of the book, that is, the number of pages cut from a full-open printing paper. The general format of books is divided into 16, 32, 64, etc. The common books are mainly 16 and 32, and the 64 is relatively small, which is mostly used for small and medium-sized dictionary books for students. [0003] The printing equipment of the book printing factory --- printing presses are divided into two categories according to the paper method: sheet...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned traditional 64-format single-book imposition printing and binding process has the following disadvantages: 1. The printing efficiency is low. In the same time period, the printing efficiency of the rotary printing machine is more than 5 times that of the sheet-fed printing machine, and no matter whether the text is monochrome, Two-color or four-color, both front and back can be printed at one time, and the printing efficiency is much higher than that of a sheet-fed printing machine

2. It is necessary to increase the folding process

3. The binding efficiency is low. On the book perfect binding production line, due to the small size of the 64-format book, it is inconvenient to adjust and operate the equipment during the perfect binding of a single 64-format book signature

In view of the above reasons, the printing and perfect binding efficiency is low and the production cycle is long when traditionally producing 64-format perfect-bound books
