Title: Ink ribbon, cartridge containing ink ribbon, and method of discriminating failure location from ink ribbon base film

Abstract: This invention relates to an ink ribbon, a cartridge containing the ink ribbon and a method of discriminating a failure location from an ink ribbon base film when the failure occurs on the ink ribbon. The ink ribbon is a sublimation-type ink ribbon manufactured from a column of the plural columns into which the ink ribbon base film is cut. The ink ribbon has a recording portion for recording column information indicating a column out of the plural columns of the ink ribbon base film, from which the ink ribbon is manufactured. The cartridge contains the ink ribbon. When a failure occurs on the ink ribbon, the column including the failure is discriminated from the plural columns of the ink ribbon base film based upon the recorded column information of the ink ribbon.
