Unpunched paper can be prepared for comb, coil, wire, VeloBind, ring binders, and other systems as long as a compatible punch is available. The broader range of binding paper can help when colour, size, weight, and punching format all need to work together. Flexibility is the main advantage because the same stock can be printed first and punched later for different jobs. However, every punch pattern requires the correct machine, die, margin, and sheet orientation. Confirm the paper size and grain direction when the document will be folded or processed further. A test stack should be punched and bound before the full run so hole alignment, page turning, and edge strength can be assessed.
