Wiro binding is another binding method we use at Gemini Digital Colour. This method is beneficial because of the ability to use any stock, there are no limitations on finishes and its cost effective.

This wrap around cover with spine gives a more aesthetic and professional finish as opposed to saddle stitching.
Whats the difference?
The only difference between PUR and Perfect Bound books is the glue used to bind them. Perfect binding uses Ethylene Vinyl Acetate (EVA) adhesive whereas PUR binding uses an adhesive called Polyurethane Reactive hence the name PUR.

In fact PUR binding is 2.5 times stronger than Perfect Binding. This method of binding is also able to withstand extreme temperatures and does not crack in cold conditions or re-melt in hot conditions.
