Abstract
A ribbon supply includes a supply spool and a ribbon material wound onto the supply spool. A tack down bond prevents unwinding of the ribbon material from the supply spool. A leader film extends from the tack down bond, with the leader film having a length that is sufficient to allow installation of the ribbon supply and connection of the leader film to a take-up spool without detaching the tack down bond.
