Saddle Stitch Binding and Saddle Stitch Printing Solutions
In the binding and finishing process, a specific means of binding pages together is done by driving staples into the centerfold of a group of signatures. Saddle-stitching and side-stitching are commonly generalized as wire stitching. That said, the side-stitching process is very rare. Most magazines and newsletters tend to be bound using saddle-stitching. In most cases, perfect binding has replaced saddle-stitching, but saddle-stitching is still one of the more effective methods for binding thick materials.
Saddle Stitch Binding Prepress Considerations – Creep and Shingling
Two primary considerations must be made during the saddle-stitched prepress phase. The first consideration is for creep because signatures intended to be saddle-stitched must to be inserted within one another. In this case, the cumulative thickness of a publication can cause the inner signature edges to protrude outside the edges of the outer signatures. Trimming, ultimately, will make all the edges even, but the result will be gradually thinner margins on the inner pages. The prepress process called shingling, which is a slight staggering of the page locations is done to eliminate the side effects of creep. The saddle-stitching process on a production line include three basic parts:

The inserting process involves printed and folded signatures being dropped into pockets on the device used for gathering. This device will carry the signatures to what is known as a saddle bar where the stitching occurs. This inserter will transfer the innermost signature in the document to the saddle bar, and here grippers and vacuum nozzles open it. It is common for additional pockets to drop secondary signatures in successive order over the first signature. Other inserts can be added to the pockets. Additionally, compressed air to force printed cards between pages is applied to add blow-in cards.

Once a publication has been assembled onto the saddle bar, it will be carried to the stitching heads. Electronic detectors are often utilized to discvoer any print copies deviating from the proper thickness required and these anomalies are discarded. The stitcher head feeds continuous wire rolls that will be cut to the appropriate size and formed into staples. Once the publication is properly positioned, the stitching head will drive staples down into the spine fold. Tools underneath the publication will bend the legs of the staples; securing the pages together.

Post-stitching, the bound units are closed and then squeezed tightly shut; forcing out any excess air and thereby reinforcing the fold. The units then are transferred over to an area with a three-knife trimmer. The unbound sides of the publication are then trimmed and the signature folds from the top and any lap allowances on the right edges are removed.

A spectrum of other equipment and parts can be potentially added into the saddle-stitching process line. For example, folders could be placed in front of the line, and this would allow signatures to be folded and then fed into an inserter in just one step. Other additions could be stackers and counters to count and stack books or documents as they are finished. A tip-in device could automatically glue extra inserts into a publication, or add end sheets to saddle-stitched publications. Keep in mind that not all saddle-stitching processes occurs on such a large-scale. A lot of print shops with basic binding capacities utilize small mechanical models that are essentially large staplers.
