One of the most important things you need to remember is to make sure you have adequate printing margins all the way around your document, but especially on the bound edge. When binding multipage documents, perfect binding, wire-o binding, and plastic coil binding will use approximately 1/8 of an inch on the bound edge. Without adequate printing margins, the holes for the wire-o and plastic coil binding may cut into important text or graphics or those elements may end up underneath the binding itself.
Without adequate printing margins, some of your text or graphics may get lost in the gutter of perfect bound books. Even if it isn’t caught in the gutter, you want to make sure that there is sufficient room on perfect bound books so that they are easy to read and do not require the reader to break the spine to read the book. We recommend at least 3/4 of an inch on the bound side for perfect bound books.
