The reason behind the popularity of saddle stitch binding is that it not only cost-effective but also takes less time in production. Moreover, this kind of binding can also be opened flat, making it quite easy for users.
Generally, saddle stitching is used for books that have less than 40 pages, and if the pages are more than 48, you must not use saddle stitching for binding. When compared to perfect binding, saddle stitching won’t save you too much cost if you are getting the printing done in China for the order of less than 500pcs. So, when it comes to binding a thick book or catalog, you must avoid using saddle stitching as it would easily break the book spine.
