How To Tips for Book Binding
Mechanical Binding
This will be a two-part article, with the first edition focused mainly on Spiral Binding. The second edition to this series will address Wire-O / Twin-Loop Binding, and Punching Patterns. Along with Punch Patterns, we also have a chart available for you on punching patterns and margin allowances. This chart would be helpful for designers, as well as pre-press personnel, to keep words and copy from getting punch holes through it. You may click the chart on the right or click here for complete information and charts.
Spiral Binding - Plastic & Metal
There are two main material differences that exist when you ask for Spiral Binding. They are more specifically "Plastic Spiral Binding" and "Metal Spiral Binding". Each element has the physical similarity to a spring, but the materials that make up the element are either of plastic or metal. They both have advantages.
"Metal Spiral Binding" starts out in the bindery as a 700-pound spool of raw wire, and is formed into its shape as it is driven through the punched holes in the binding edge. The wire has a lower material cost, because the final forming takes place during installation into the books. The products that you commonly use Metal Spiral are Calendars, Educational Books, and smaller Reference Guides. One disadvantage of Metal versus Plastic is crushability. If the element is smashed or stepped on, its shape is usually ruined.
"Plastic Spiral Binding" starts out in the bindery by an order being placed for the exact size and color specific to each job. The elements are pre-formed at the manufacturer into the spring shape, and shipped into Wrap-Ups. These elements are spun by a machine through the punched holes of the book. When the element reaches the end of the book, the spinning stops and knives will cut and crimp each end of the element.
Plastic Spiral Binding has excellent crushability factors, for it can always maintain its original shape. The elements are much safer with respect to the cut ends, so they are better for applications in Children's Books, Cook Books, and Street Guides. Any type of Mechanical Binding that usually results in frequent utilization should consider Plastic Spiral Binding for its durability.
