Unpunched colored paper can be prepared for plastic comb, spiral coil, wire, VeloBind, ring binders, and other systems when the correct punch is available. It may also remain unbound for inserts, signs, notices, or handouts. The important limits are the paper size, weight, punch capacity, hole pattern, and margin required by the chosen system. Do not assume one punch can create every format, and do not process a stack thicker than the machine rating. Heavier paper may require fewer sheets per lift than standard bond. Keep a correctly punched sample for each binding method and label equipment settings clearly. This reduces alignment errors when the same pink stock is used across several document types.
