Perfect Binding

Perfect binding is an adhesive-type process (also known as paperback binding) that relies upon the strength of the glue to hold the leaves of the book in place. Because of this, it is a method best suited to papers with an open structure or porous coating, such as bond, copier or offset paper, and matt artpaper.

Thinner papers also bind with greater strength than thicker ones, and factors such as grain direction and type of printing, ie; litho, digital, copier etc. can make a considerable difference to the end result.

The main advantage to this process is the neatness of the finished item, with the wraparound cover giving a square spine that can carry text. Disadvantages are that replacing sheets after binding is not possible, and that the books will not open flat without some stressing of the spine by the reader, especially if they are thin. For books that will need to open flat we recommend wire-o, spiral or comb binding.

We have a Horizon BQ-270V binder utilising “Planamelt” glue that gives a bind strength close to that of “Polyurethane Reactive” (PUR) glue. The binder allows a maximum spine length of 320mm and is suitable for run lengths from 1 upwards. The minimum thickness of the text block that we can bind is 2mm. Collation of the text, either as flat sheets or folded sections, can be undertaken by ourselves. If preferred, the customer can supply us with pre-collated sets for us to split or text blocks ready for binding.

Please note that we will normally require about half a dozen extra inner sets and covers to enable us to set-up our machinery.
