Spiral binding vs hard binding
Spiral and wiro lie flat for notes and vivas. Hard binding is the rigid cover used for thesis submissions and keepsake books. Choose from Printvity’s binding products.
Spiral (plastic coil)
Pages turn a full circle and the book lies flat on a desk. Best for college projects, study notes, training manuals and anything you write on. Plastic coil is light; it can crush if a bag is overpacked.
Wiro (metal twin-loop)
Same lay-flat behaviour as spiral, with a stronger metal loop. Prefer wiro for office manuals that will be opened every day.
Hard binding
A rigid cover and glued or cased spine. It looks like a library book. It does not lie fully flat. This is the usual thesis and dissertation finish. Add gold foil when the campus wants a stamped title.
Soft cover (perfect bind)
A square paperback spine. Needs enough pages to form a book block. Good for novels, proposals and reading copies — not for a 20-page stapled report.
