Wire-O Binding
Also termed as double wire binding or twin loop binding, wire-O binding uses double metal wire to bound all the collected interior pages. In this binding, there is a square hole drilled, with many wire color choices for the clients like black, white, silver, etc. This is one of the best methods that you can choose when you want your documents to open all the way to back or lie flat on your desk. This will save a lot of space on your desk as well.
The wire size will depend on the thickness of the book, whereas the margin on the spine edge must be around 5mm. The margin on the spine edge must be larger than the margin on the cutting edge. So, for instance, if the margin on the cutting edge is 5mm, the margin on the cutting edge must be at least 15mm. So, after binding, the texts are in the center of the page.
In this mechanical form of binding, the wire used is made of metal. The unbreakable binding that is formed here is formed by two loops of wires. This binding option can give you a very uncluttered look because the hinges are hidden inside the back cover. Another reason why people choose this type of binding is because of its sturdy and stable nature. Whether you are designing a custom notebook or a journal, this type of binding is what you should opt for in such cases. They serve as the perfect binding option in gifting scenarios.
