Spiral binding and wire binding are often used when you need the book or manual to lie flat when open. For this reason they are commonly used for text books.
However, one drawback in these binding methods is that there is no spine to the book and so the book is not readily displayed (or located) on a bookshelf. If you want to incorporate a spine into the design of your spiral or wire bound book, the option to choose is Canadian binding. This is a way of binding in which pages are wiro-bound, but a wrap-around cover is also bound to the document, giving it a spine that can be printed on. The cover can be either soft or hard and you can choose half-Canadian or full-Canadian. Drop me an email if you want to find out more.
