What binding method uses staples to hold pages together?

The binding method that uses staples to hold pages together is saddle stitch binding. In this technique, folded sheets of paper are stacked and then stitched along the fold with staples. This method is commonly used for smaller publications such as booklets, magazines, and brochures, as it is cost-effective and allows for easy flipping through the pages.

Saddle stitch binding is advantageous for projects where a lighter binding is acceptable, and it allows for a flat lay of the pages, enhancing readability. This binding method can efficiently bind a number of pages, typically up to around 64 pages, depending on paper thickness. Because of its simplicity and affordability, saddle stitch is a popular choice in various print applications.

In contrast, the other binding methods mentioned do not utilize staples in the same way. Case binding involves sewing the pages into a hardcover, perfect binding glues the spine to create a smooth edge, and Wire-O binding utilizes wire loops to hold pages together, which creates a unique finish and allows the document to lay flat but does not involve staples.
