Book Printing Lingo: What Is Wire-O Binding?

Wire-O Binding produces a sophisticated and professional-looking document

Wire-O Binding, also known as Twin Loop, Double-Loop, Double-O, Duo-Wire, or simply Wire Binding, is a popular method for joining the pages and cover of a bound document.

Wire-O binding offers many of the same benefits as spiral coil binding, but is more sophisticated in appearance. As such, it produces a very impressive document. Also, it can accommodate pages and inserts of varying thicknesses, including dividers or index tabs made from heavy cardstock.

The Wire-O binding method utilizes pre-formed pairs of wire loops that run along a C-shaped unit. These wire loops are inserted through holes that have been punched through the book's cover and pages. The loops are then crimped closer together until they form a perfect circle, thus securing the cover and pages as an assembly, yet allowing them to open freely.

The Benefits of Wire-O Binding…

1) The pages can be opened a full 360 degrees. A Wire-O bound book can fold all the way back upon itself and yet still remain flat, so it provides for easy reference while taking up minimal room on a desk or table. This makes Wire-O binding an excellent choice for reports, directories, cookbooks, music books, instructional books and maintenance manuals. Atlases and travel guides are also commonly Wire-O bound because they are easier to manage when traveling. And because they can open fully, it prevents important information from getting buried near the book's spine.

2) The pages turn easily and stay put. When opened, the pages of a Wire-O bound book rotate around the wire loops with very little resistance. So, unlike a perfect bound or saddle-stitched book, the pages of a Wire-O bound book have no spinal tension in them. This allows the pages of a Wire-O bound document to stay put without having to be continually held open to view the contents, which is an ideal feature for a journal, manual or workbook. In addition to books, wall calendars are often created with the Wire-O binding method to ensure the pages flip easily and the lack of spinal tension allows them to hang flat against the wall.

3) It can accommodate low page counts or high page counts. Wire-O loops come in a variety of sizes to accommodate books of varying thicknesses. The more pages the book has, the larger the wire gauge and loop diameter must be for proper function and aesthetics. In addition to the natural metal color of silver, Wire-O binding is also available in certain painted colors.

4) It works well with index tabs. Because the Wire-O binding method allows pages to turn freely and stay put without the need to manually hold them open, it is often the best choice for bound projects that require tabbed page dividers. Dividers with printed tabs are the perfect complement to any reference document - such as a report, presentation, training manual, directory, etc. - because they allow the user to quickly locate a specific page or topic. The tabs are often printed in varying colors and/or coded numerically to make them even easier to use.

5) It is a readily available binding method. Though not quite as readily available as spiral coil binding, Wire-O binding is still a popular binding option, particularly for shorter production runs. Its popularity stems from the fact that it is a rather straightforward process that requires no adhesives, folded signatures or extensive preparation. Also, the metal loops are often inventoried in a variety of sizes and colors to complement a wide range of documents.
