DOCUMENT BINDING

What We Do

DIFFERENT WAYS TO BIND DOCUMENTS

We can offer various ways to bind documents, each bringing its unique style and suitability to different applications.   Choosing the right way of binding will enhance the professional appearance of your book or manual and ensure it is fit for purpose with expected longevity.   We’ve briefly explained and shown examples of some different types of document binding below.   We look forward to discussing what binding method is most suited to your project and budget.

Document binding is typically the final stage in the print finishing chain, after printing/copying and laminating/encapsulating.

Comb Binding

Comb binding is one of the simplest “office” ways of binding a document.

  • To comb bind, we punch a series of rectangular slots along the opening edge.  21 slots is standard for an A4 document. Then we apply a sprung, plastic comb and close this onto the punched slots.
  • Advantages of comb binding are, the finished book opens flat, making pages easy to read and copy.   You can open and re-use the comb (using a dedicated comb opener/closer) with pages added/replaced. 
  • We can supply plastic combs in various colours and sizes to match your project.  Also, we can source combs to any RAL colour for large orders or regular customers.
  • Whilst we still offer a comb binding service, most of our customers prefer our wire binding service or coil binding service nowadays, for the enhanced presentation and permanency these alternative methods of binding offer.

Wire Binding

Wire binding is a more professional way to bind documents.

  • We punch the document and cover with a series of small round or square holes.   The holes are evenly spaced, typically at 3:1 ratio (three holes per inch).  Then we close a pre-formed wire mechanism onto the booklet.   For very thick documents, we use a 2:1 ratio.
  • Similar to comb binding, the finished book opens flat, however once the wire is closed, it cannot be opened to add or replace pages.
  • Binding wire mechanisms are readily available in popular colours and various sizes to suit booklet thickness.   We can also source wire mechanisms to RAL colours matching your corporate imagery.

Coil Binding

Continuous plastic coil binding uses the same punching process as for wire binding, however is finished by threading a continuous plastic coil through the punched holes.

  • We punch the document at a 4:1 ratio for coil binding, using an oval die-set.
  • Coil binding offers the huge advantage of permanency.   This is because pages can only be removed by intentionally tearing them out of the spine.   Also it is not possible to add or replace pages.
  • Coil binding is therefore perfect for checking logs and other documents that are handled continuously and folded fully back on themselves.
  • It’s worth being aware that the two sides of the an opened-out coil bound booklet are offset by a couple of millimetres, as the coil is continuous.
  • Plastic binding coils are available in popular colours and various diameters to suit different booklet thicknesses.   We can provide coils to specific RAL colours on volume orders.

Saddle Stitching

Saddle-stitching simply secures loose leaf papers down the folded middle with staples.

  • Using the least materials of all binding methods, saddle stitching is one of the most cost effective ways to bind booklets.
  • There are a couple of considerations however – generally it is good practice to trim the opposite edge to the stitch, to give an even finish.  Otherwise the inner pages would stick out further than the outer pages, which does not look professional.
  • Depending on the thickness of the booklet, some customers like the saddle stitched spine to be finished with a square fold, to make them sit flat.

Perfect Binding

Paperback books are the most well known examples of perfect binding.

  • Giving a permanent and very professional finish, pages cannot be removed, added or replaced.
  • Pages are more difficult to photocopy, compared to other binding methods, as the book doesn’t open flat.
  • There are two different popular types of perfect binding:
    • the simpler process using EVA (ethylene vinyl acetate) hot melt glue & roller application,
    • the more complex PUR (polyurethane reactive adhesive) process gives the strongest finish, suitable for thicker books and catalogues.
