Everytime, our clients ask for a sample book printing before the mass print, that's OK. But since we are serious company, we have to explain why we choose perfect binding for the sample even the final children book will be section-sewn binding. In order to save our explanation time, I write this article to everyone who may face the same questions. First, we have to understand 2 types of book binding.
Perfect Binding
Perfect binding is a highly favored bookbinding technique, commonly used for creating paperback books, magazines, catalogues, and other printed materials. The process involves arranging the pages into book blocks, trimming them to the desired size, and then gluing them along the spine using a strong adhesive. These pages are then attached to a card cover, usually made from paper stock between 260gsm and 300gsm, giving the finished product a professional and polished look. This binding method is especially popular due to its simplicity and affordability, making it an ideal choice for large print runs where cost-efficiency is important.
In addition to standard perfect binding, there's a more durable option known as PUR (polyurethane reactive) binding. This enhanced method uses a special adhesive (PUR) instead of traditional hot-melt glue (EVA). The result is a much stronger, more flexible bond that holds up better under repeated use and exposure to temperature changes. Because of its superior strength, PUR binding is often the preferred choice for high-quality publications, such as art books, cookbooks, and textbooks—any project where durability is a priority. Books printed on coated or glossy papers, which are harder to bind, also benefit from PUR binding's enhanced strength.
However, while perfect binding is visually appealing, it may lack the durability needed for heavy-use books, particularly with standard adhesives. For projects requiring maximum longevity—especially for items that will be frequently opened and closed, like manuals or textbooks—opting for PUR binding or even a more robust method like Section Sewing can provide added strength.
Advantage:
- Sharp, perfectly trimmed edges for a clean, professional look
- Cost-effective, particularly for larger print runs
- Quick production time
- Suitable for various book sizes and types
Disadvantage:
- Standard perfect binding with EVA glue has lower durability, especially under frequent use
- Not ideal for heavy or coated papers unless using PUR adhesive
Section-Sewn Binding
Section-sewn binding, also called thread-sewing, is renowned for its durability and longevity. This method involves grouping the pages into smaller sections (called signatures) and sewing them together with thread. These sewn sections are then firmly attached to the cover, whether for a case-bound hardcover or a paperback book.
This technique not only ensures a strong bond between the pages but also allows the book to lay flat when opened—perfect for books that require frequent handling, such as reference books, cookbooks, or textbooks. While section-sewn binding is more labor-intensive than other methods like perfect binding or PUR binding, the long-term durability it provides makes it a preferred option for high-end or frequently used books.
Another key benefit is its resistance to wear and tear. The sewn pages are securely connected, preventing them from loosening over time. This binding method also offers an elegant finish; the visible threads along the spine lend a sophisticated touch, making it an attractive option for special editions, art books, and collector’s pieces.
Advantage:
- Exceptional durability and strength
- Allows the book to lay flat
- Ideal for high-page-count books
- Premium look with visible thread details
Disadvantage:
- More costly than other binding techniques like PUR or perfect binding due to the manual process involved
How to Choose the Right Binding? Here is the my advice.
When it comes to bookbinding, one common debate centers around the choice between sewn binding and glue binding. Glue binding methods like perfect binding (EVA) or PUR binding are popular for their cost-effectiveness and efficiency, especially in large print runs. They provide a clean finish, making them ideal for magazines, catalogs, and certain types of books.
On the other hand, sewn binding offers unmatched durability and flexibility. Unlike glue binding, sewn binding allows books to lay flat when opened and ensures they can endure frequent use over time without pages falling out. This makes it an excellent option for high-end books such as reference materials, art books, and any project that demands longevity.
Ultimately, the decision between sewn and glue binding depends on the specific needs of your project. Key factors to consider include the content type, how often the book will be used, your budget, and the desired aesthetic. For projects with a focus on durability and presentation, sewn binding might be the best option, while glue binding is often chosen for cost efficiency and speed.
Understanding these binding techniques, including case binding, perfect binding, saddle stitch, and section-sewn binding, helps ensure your book achieves the right balance of functionality and quality for its intended purpose.
Now you can understand:
If you don't very much care about the binding, I mean the sample, you can pick Regular Perfect Binding, because it is a sample book printed by our HP Indigo 100K Press.
If you have enough budget for the project or the sample, we make the Section Sewn Binding for the sample book. ;-)
