How to reduce printing costs in the binding process

The commonly used book binding forms include saddle stitching, flat stitching, sewing thread binding, glue binding, and the like.

Saddle stitching, staple stitching and glue binding can be designed to be smaller in the central cross-page center. If it is in the form of a flat book, the heart of the center's cross-page book must be relatively large, because the flat book's mouth is about 5mm.
When designing a manuscript, the size of the body font, the density between the lines, the width and width of the blank space around the caption, the line of the title and the blank line, and so on are all related to the cost of the book. For example, if a book is an ordinary 32-page book, the original design is a horizontal 5-character word with 26 words and 25 lines on each side = 650 words. There are 5/8 lines between the lines and 240,000 words of manuscripts. A total of 370 faces are required. Rows of 26 words × 27 lines = 702 words, 1/2 between the lines, only 342 planes; a difference of 28 surfaces.

We can reduce the cost of the book at all stages of printing, paper, and binding. Of course, it does not mean that the layout is getting denser and better, such as children's books, the words should not be too small and the line spacing should not be too narrow. Under the premise of adapting the content of the manuscript and the readers, save paper materials as much as possible to reduce the cost of the book.

Reasonably determine the cover size

When designing the cover, the design should be based on the finished product size, spine thickness, and size of the mouth. When designing the size of the mouthpiece, it is generally possible to make the mouth slightly larger without wasting paper and facilitating printing. The majority is more than 30 mm. However, some cover designers do not understand the paper specifications, the number of openings, and the performance of the printing press. When designing the cover, they do not fix the size of the mouthpiece according to the number of paper sheets. After the platemaking, they often do not meet the requirements of the paper size specification and cause waste. . Most book covers now require lamination after printing, which in turn increases the cost of lamination.

For example, a set of books is divided into upper and lower volumes, and 32 books are opened for the Big 32. The upper and lower volumes are about 600, printed on 52g paper, and the thickness of the spine is 22mm. The cover is printed using offset printing, and the upper and lower volumes are each printed at 20,000. The cover is overlaminated. Because designers do not understand the paper specification opening, the design of the mouth is 65mm, such a large mouth, you need to use 787×1092 1/16 paper printing. If the design is based on the number of paper sheets, and the design of the mouthpiece is 40mm, it can be printed with 787×1092 1/8 paper. The printing fee, paper, and laminating fee of the two were actually different by about 4,000 yuan. From this we can see that when designing the cover of a book, designers must understand the paper specifications and opening numbers, and try to consider reducing the cost of the book and avoid unnecessary economic losses.

Some cover and front and rear ring lining design is relatively simple, to print a few spot colors, the amount of printing is not large, plate-making can consider making copper and zinc plate, printing can be used plate machine printing, because the plate printing is a single small sheet printing, can be used Flowers can also be cut into small sheets with scraps of paper. This can increase the utilization of paper, and the cost of platemaking can also be reduced.

Binding material

When selecting hard cover materials, the use of leather, cotton, hemp, silk, wool and other fabrics should be controlled. Use tough paper, paint paper or lacquer, etc. as much as possible. In addition to special needs, try to avoid using real gold foil. Hot stamping materials can be replaced with anodized aluminum or color chips to reduce the cost of the book.

printing art

For general 32- or 16-open single- and bi-color books, the number of prints is more than 50,000 copies, and the printer is usually arranged for printing. Because the speed of the rotary machine is fast and the printed pages have been folded, the printing costs are lower than those of the flatbed printer. However, for books under 50,000 volumes, the lead row can be printed by large automatic, small automatic or eight-page machines; the laser photocopying can be printed by a B-B double-sided offset printing press. This is a printing press that prints books and magazines. Paper printing fee calculation; or with 01, 08 type monochrome offset press printing, this offset printing press is a single-sided printing press, according to the color order to calculate the printing fee. However, using a B-B offset press is faster than a monochrome offset press and the printing cost is low. For the picture book with high quality requirements, two-color or four-color offset printing machines should be used as far as possible; for large-scale, such as New Year pictures, front and back ring linings of books, etc., a single-color offset printing machine should be used for printing, and the printing quality is better.
