Binding: The whole process of wireless binding for books

Cover tape

For the cover, tape is allowed to be wiped over the entire length from head to toe. If the spine length of the sticker is 111/2 inches (292.1 mm), then the cover length should be at least 113/4 inches (298.4 mm). Locate the center position, the head and feet are over 1/8 inch (3.2 mm). When the size of the cover and the sticker are the same, the wireless perfect binding operator must use a mechanical timing scraper when gluing the book and the side to prevent the glue on the work wheel from flowing out during operation, which reduces the production speed and quality.

Wireless binding cover design instructions

As far as possible, make Sival parallel to the direction of the spine;

To get high-quality products, make book indentations on the die-cutting machine;

For thin books, avoid using thick covers (≥10pt);

The ink, varnish and UV coating of the inner front seal should not enter the indentation of the book, and the distance from the spine should be greater than 1/16 inch (1.6mm).

Keep the ink and layers of book stickers away from the edges of the spine;

The cover sample required to be transported has a printing machine gripper and side guide marks.

Sticker preparation

Perforate the spine and the head of the sticker to release the compressed air in the pages. Then, the pressure plate presses these books together as close as possible. This method is very important for stacking books. Don't place the stickers in the opposite direction when refilling paper. Instead, place them in the same direction. Use molds of opposite curvature (eg concave and convex) to work together on a book. A very good wireless perfect binding requires that the book be clamped together before being glued to the cover, and then passed through grinding and rubber wheels. If the clip is not tight, the glue may spread between the stickers. Once the post is not consistent with the habits when it is unfolded, the job has a problem.

Insert folding pages in the book

Insert folding, half-sealing folding, roll folding, etc., the requirements for cutting blanks are 1/8 inch (3.2 mm), so the folding does not need to be glued, and 1/8 inch should be reserved , So this kind of folding cannot be aligned with the whole book pages. If there are too few reservations, it will limit the operation ability of the wireless bookbinding personnel, for example, it will be more difficult when doing cross-page positioning. Similarly, for the inner back cover of the bound booklet, 1/8 inch headspace and layout space are also required. The best way is to confirm with the binder to ensure that all booklets The hinges have the correct size.

Die cutting

Using die-cutting method can accurately determine the size of the book.

Auxiliary equipment

DuPont's FoldoutMylar? Equipment, which has the function of marking the book room, but the use of this equipment will increase the cost of wireless binding products. And this interleaved label looks very interesting. This kind of machine will only put a mark between the book posts, and will not print marks on the cover and single-page book pages. Try to use a variety of post-press processing functions (such as: die cutting, foil stamping, marking and compression packaging, etc.) on the binding job, so that the work process will be more coordinated and easier to control.

Compressed packaging

Don't be smart in small places and waste in big places. You can use compressed packaging for books to prevent confusion. If it is a small amount of work that requires refined packaging, the investment to compress the packaging to the minimum may be the most secure.

Food Additives are substances added to food. Some additives have been used for centuries. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.

The advantages of food additives are these followed:

1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
