Perfect binding: the whole process of wireless perfect binding of Kids Hardcover Books

Perfect binding: the whole process of wireless perfect binding of Kids Hardcover Books

cover tape

For the cover, tape is allowed from head to toe. If the signature spine length is 111/2 inches (292.1mm), then the cover length is at least 113/4 inches (298.4mm). Locate the center position, 1/8" (3.2 mm) beyond the head and foot. When the cover is the same size as the signature, the perfect binding operator must use a mechanical timing scraper when gluing the book and sides to prevent the glue from running out of the work wheels during operation, which can reduce production speed and quality.

Perfect Binding Cover Design Instructions

As far as possible, make the silk as parallel to the spine of the book;

To get a high-quality product, make book indents on a die-cutting machine;

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

The ink, varnish and UV coating on 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 signature ink and layers away from the edges of the spine;

It is required that the cover sample to be conveyed has the printing machine mouth and side guide marks on it.

Bookmark preparation

Perforate the spine and the header of the signature to release the trapped air in the pages. The platen then presses these Kids Hardcover Books stickers together as tightly as possible. This method is very important for the stacking of bookmarks. Do not cross the signatures in opposite directions during one feed, but place them in the same direction. Use molds with opposite curvatures (eg, concave and convex) to work together on a book. A good perfect perfect binding requires the book to be clamped tightly together before being glued to the cover, then passed through a grinder and a glue wheel. If it is not clamped tightly, it may allow the glue to spread between the signatures. Once the signature does not unfold as custom, the job is problematic.

Folding pages in the Kids Hardcover Books

Insert folds, half-folds, roll folds, etc., all require 1/8 inch (3.2 mm) of cutting blank, so folds do not need to be glued, and 1/8 inch should be reserved. , so this fold cannot be aligned with the entire book page. If the reservation is too small, the operation ability of the perfect binding personnel will be limited, for example, it will be difficult to locate the spreads. Similarly, a 1/8 inch gap is required on the inner back cover of a perfect bound booklet. The best way to do this is to check with the binder to ensure that all The folds all have the correct size.

Die cutting

The size of the book can be precisely determined by using die-cutting.

  Auxiliary equipment

The FoldoutMylar® device from DuPont, which has the function of marking the label between the signatures, increases the cost of perfect binding products. And this staggered label looks interesting. The machine only affixes the logo between the signatures, not the cover and individual pages. Try to use as many post-press functions as possible on the binding job (eg: die-cutting, foiling, marking and compression wrapping, etc.), so that the work process will be more coordinated and more controllable.

Compressed packaging

Don't be shrewd in small things and waste big things. Compression packaging for books can be used to prevent clutter. If it is a small number of jobs that require refined packaging, it may be safest to compress the packaging to the smallest investment.
