Discussion and Reflection on Modern Bookbinding (I)

[Editor's note] As the publishing industry has increasingly demanded the quality of book and bookbinding, and the publishing cycle has become shorter and shorter, in recent years, major printing and printing plants across the country have introduced or are preparing to introduce foreign advanced binding equipment to make up for it. Insufficient postpress processing capacity.
Nanjing Aide Printing Co., Ltd. is an earlier domestic manufacturer of hardcover linkage lines, with strong hardcover and flat capacity, not only advanced equipment, well-equipped, and good product reputation, but also has many management and process technology management Insights. This article provides insights on the management and improvement of binding process technology, printing balance and social division of labor among several senior and middle managers of the company.
First, the unification of process technology is the guarantee of quality and efficiency. The modern printing plant not only has advanced equipment performance, but also has a complete set of equipment, and it is fast and efficient. If you leave the two bases of reasonable technology and scientific management, no matter how advanced equipment, at best, it is just a sample in the exhibition hall.
Aide Company is a modern thin paper type book printing factory. More than 90% of plate making, printing and binding equipment are selected imported equipment and are fully furnished. After more than a decade of production practice, it has been proved that only the process technology between processes is unified, product quality is guaranteed, and equipment efficiency can be fully realized.
1. Platemaking is currently the outpost of printing and printing companies. Computer typesetting has become very popular. Publishers or customers generally provide films. Carefully check the quality of the manuscript and prepare for printing. The process requirements for the assembly and compliance are the work before or after the imposition. For example, the edges of the printing paper and the side of the side pull tabs must be consistent with the side of the bookbinding folding machine; the difference between the front half and the back half of the width of each side of the fold (large and small sides) must meet the requirements of the sewing thread Consistent (especially with open-edge signatures); glue-binding, wire-stitching, and bookbinding; each side of the board is biased toward the edge of the flap; the margin must be set reasonably; hardcover book, paperback cover, especially the spine , must be based on the center of the finished product outside the basic edge of the basic bleeding line (for paste seal, seal); special copy, ring lining, title page, map, etc., the position of the post number set with the folding machine performance and the next process Job characteristics match; 60G / square meters thick paper round ridge hardcover book 40 percent of the bookbinding binding, 扒 round ridge into the beginning, the tail often appears about 5 posts have the phenomenon of steps, using the first, the end of a few posts off the imposition, Printing, and then cut into four fold after the binding process can be resolved; each post should have a short title, typography, mark, rules lines, folding lines, cutting lines, finished lines, edge control lines, etc. All should be completed for the next step; to be dried, folded every blueprint, for printing Test; In addition, the production of thick, thin like a book, developing-shell technology and so on, all of the printing, binding, inspection, quality, efficiency has an important significance.
2. Printing must be linked to the first step. First, set the process requirements according to the plate making, cut out the machine paper that meets the process size, and print the corresponding rules, lines, and bleed blocks to check the situation of the registration and rinsing.
When a single-sided single-sided printing or a PS version of more fight, need to turn the small paper, while the mouth does not change the reverse side, you should change the side of the rules to ensure that both sides of the printing rules are the same.
After each page of the first inspection, the folded page should be compared with the blueprint. At the same time, the difference between the widths of the first half and the second half of the signature should be more than 3mm. There should be a difference between the size and the edge, and each line should be the same (for the lock line); (Tiantou or footer) The cutting quantity must meet the technological requirements (especially the open book printed by the rotary machine). After all the sheet-fed prints are inspected by large sheets, they are handed over according to the rules.
In accordance with the needs of the process, our company has made technical transformations to TEMC rotary printing of the British company TECMSON. Without changing the performance of the machine, the company then dragged the domestic small folding machine so that it can only output 24 faces/posts from the original. , Joining the book, became a single post that also has 48 faces/posts. Solve the weaknesses of thin paper, such as typography, post, page matching, and sewing, etc., and solve the wrinkling defects of original folds, laying the foundation for the next binding process to improve efficiency and ensure quality. .
3, the continuous integration of the binding process is crucial for the binding process, and continuous process is essential. When checking the edge of the paper and the rules of the bleeding block are the same, they can press the fold line to adjust the folding position. For multiple impositions, the rules can be made by sloping and squeezing. Cutting by tangent lines can efficiently fold the pages.
Paste is my company's use of more technology, the reason is not to use posts, because the paste is high efficiency, 1 paste can be top 3 sets of stickers, and quality assurance.
Collation, rubber binding linkage lines can be linked glued, but also glued and collated respectively at the same time, only need to adjust the machine, you can guarantee quality and efficient production.
In terms of lock line, our company not only has domestic SXB430 sewing machine, but also has Italian semi-automatic EF1887 type and EF1888 type thread machine and the latest type of ASTRONIC180/51 automatic sewing machine. The maximum binding format is 510mm x 320mm, the minimum binding The format is 150mm x 75mm. It is parallel-locked and cross-locked. It can store and recognize high-end book signatures without any signature in the computer, ensuring that there are no more posts, less posts, and incorrect posts. Not only can lock 28G/m2 thin paper 24 surface/tie thin stickers, but also can lock the large open book, attracting a lot of high-end product binding business. (To be continued)
