Children's Shaped Book Making Experiences

The production of children's special-shaped books is very representative. Also very particular about it. From the initial material purchase to the final product handling is very strict. The used paper is generally a gray-white paper with a basis weight of 300-400 g/m2. The main production process is: printing-overgreasing (laminating)-die cutting-indentation-stitching-punching-dehumidifying and drying. Here is a brief review of the process of making special-shaped books.

1. The moisture content of the selected paper is lower

Many children's exotic books exported to Europe and the United States require moisture content of about 17%, otherwise because of environmental differences will cause "foliage" phenomenon, and the adhesive should also use high viscosity, to avoid excessive water in the process of paper Causes the water content to rise.

2. Die-cutting and punching are essential when making profile books

In general, thin books are better prepared by die-cutting or punching after the first bookbinding. However, the thick bookmaking methods are different. Some of them are finished and then die-cut, some are die-cut, special-shaped single pages, and then bound or pasted. . At this time, there are certain requirements for the selection of papers, adhesives, and pastes. If there is no previous test, problems will often arise. First of all, the material must be accurate, and special attention should be paid to the paper cutter cutting paper may have errors, so it must not cut too much at one time.

3. It is an important part of the book binding

Since various sheets of paper have different retracting rates after being subjected to water, it is best to use the same paper sheet to avoid bending, and at the same time, it is necessary to have a good grasp of the time to complete the glue.

4. Hardcover shaped book corner technology is more difficult to master

Hardcover shaped books often have both outsourcing corners and inner wrap angles, which are easy to cause the side exposed cardboard primary colors, affecting the appearance, so the reader can see that there are a lot of special-shaped books in the wrap angle of the substrate has a pen point marks.

5. A lot of hardcover shaped books work hard in a book cover or box

For example, when the letter box and the inner page are pasted, a die-cut thin cardboard is sandwiched in the middle, and a turntable with a graphic and a double-sided printing is fixed on the gap between the letter cover and the inner page. This can be changed by turning the dial. The graphic content in the book is very new and interesting.

6. Paperback Shaped Book Variety

Some have a unique appearance; some use 3D printing; some have a transparent plastic sheet at the center of the inner page, which shows a special effect by superimposing the pattern printed on the back paper; there are also some origami in the inner page. When open, origami opens and presents various shapes, etc. In short, there are various types. However, special attention should be paid to the strength of special-shaped books, and the overall strength of the book should not be insufficient to ensure the profiled effect. This can easily lead to squeezing marks or falling off of the inner pages.

7. Different products produce different degrees of fineness

Take the lunar ear in the hardcover notebook pages as an example, the domestic processing methods mostly use a period of manual punching, and the produced products are of different depths and are ladder-shaped. The use of automatic page turning, punching equipment, cut out the lunar ear is very neat.

8. After the production of shaped books is completed

Shaped books must be placed in the dehumidifier room or drying room after the completion of the production to ensure that the water content of the paper meets the customer's requirements.

The costs and losses of making special-shaped books are very high. Therefore, the characteristics of each link should be paid attention to when crafting the craft. In particular, the details are often prone to problems. Therefore, more proofing tests must be conducted to determine the process parameters and find the processing rules. Although it is difficult and costly to make special-shaped books, with the continuous improvement of post-press equipment, the products will be more colorful, novel and unique, and have different functions, opening up a new world of publishing and commercial printing.
