Print finishing and binding techniques, when executed properly, can significantly enhance the value of your project.

A multi-page document, such as a brochure, book, or booklet, requires finishing to achieve the best possible look and feel. The process of gathering and assembling multiple pages is known as binding. There are various methods for binding, and below are techniques that may be familiar to you, along with some that might introduce you to new possibilities for elevating your bound project.

Saddle Stitching

Saddle Stitching is a method similar to simple stapling, where groups of four pages (known as a signature) are collated together and stitched using metal wire at the center fold. The wire is stitched inward from the outer spine and is visible on both the inside and outside of the document. Depending on the weight and thickness of the paper, you can bind from 8 pages (2 signatures) up to 72-84 pages using this method. However, a higher page count can cause the pages to extend beyond the spine, a phenomenon known as creep. This can be managed by properly imposing the pages for printing.

Square Back Saddle Stitching

A recent advancement of the saddle stitch is Square Back Binding, which elevates the saddle stitch to a new level. This technique results in a square spine formed by a special module inserted into the machine. The “square folder” applies pressure to the spine of the saddle-stitched book, creating the flat spine typically found in perfect-bound books. The advantage of this technology is that it accommodates a higher number of pages. However, it’s important to note that the staples remain visible on the spine, which can impose certain design limitations.

Side Wire Stitching, also known as stab stitching, involves piercing a metal wire through the edge of loose pages from front to back. The wire is then folded back on itself and covered using binding tape or a custom-printed spine cover.

Perfect Binding

Perfect Binding employs grouped sections or loose pages (leaves) that have a hot glue coating along the edge and are then placed inside a separate wrap-around cover. This binding method is considered premium and requires a minimum spine thickness of 3mm. Contrary to popular belief, simply increasing the weight of the cover while reducing the weight of the text pages is not advisable, as this can weaken the binding. For bindings with a minimum thickness of 3mm, it is better to use a cover thickness around 250gsm and increase the text page weight to 170gsm for a more substantial and durable finish.

Wire-o Binding

Wire-O Binding consists of a document made up of loose leaves with a loose front and back cover, which are punched along the edge and held together using wire. These wires come in a wide variety of colours, lengths, and diameters to suit almost any application. This binding method allows documents to lay flat and can be easily combined with different page widths to create stepped catalogues, as well as accommodate tabbed dividers.

Half Canadian Wire-O Binding

This method is similar to standard Wire-O binding but includes the added benefit of allowing for a printable spine and partial covering of the wire. A single-piece cover is creased and folded around punched loose leaves, and a wire comb is then bound through the back cover only. This creates the appearance of a spine, while the comb is only visible from the back of the document.

Full Canadian Wire-O Binding – This method offers a finish very similar to Half Canadian Wire-O binding, with the key difference being that the wire is bound through both the front and back covers, while still providing a printable spine.

Plastic Comb Binding – This method is similar to Wire-O binding, although it is currently less popular. It is another option for gathering loose leaves with various cover options. Instead of square or round holes as in Wire-O binding, a comb binding uses a rectangular slot punched along the binding edge. After the document is punched, a comb is stretched open and the document is hooked over it. Once the comb is closed, the teeth of the comb secure the pages under the spine element.

Chicago Screw Binding

This binding method collates loose sheets together to form a book block. Two to four evenly spaced holes are drilled along the spine side, approximately 1 cm from the spine edge. The Chicago Screw consists of a two-part element with a screw that sinks into a threaded barrel. These are inserted through the holes, and the slotted cap screw is tightened. This method allows for creative cover options, such as duplex board, which can be combined with a Swiss-style bind where the book block attaches to the back cover.

When considering binding options, the choice of cover material is crucial. Some documents work well with 250gsm or 300gsm gloss or silk art board, while others may benefit from Folding Box Board (FBB), which offers a different level of bulk for added protection. Publications with a longer lifespan may feature lamination, available in gloss, matte, or soft touch finishes. It’s also possible to use a lightweight jacket over the cover, which tucks into the inside front and back covers.

Certain covers can incorporate French flaps, where the cover folds back into the front and back, creating a more prestigious finish and providing additional durability.

The scope of book binding is vast. In an age where internet-driven print services can dictate your options, engaging with an experienced bespoke print house can yield better results, allowing for greater creativity. Unlike internet “shed” portal print providers, we don’t restrict the paper stocks used; you can vary the paper within your publication.
