The ribbon has a strip which has on one of its faces a succession of sequences of transferable colourants (1,2,3). The colourants are transferred to a surface by heating. Each colourant is preceded on the ribbon by an index mark (4). The index mark is separated from the colourant by a separator region (5) that has different characteristics to the index, to allow clear identification of the index. The separator may be of a different colour to the index, or may be the same colour but of different length. The index carries a code (7) that indicates the characteristic of the colourant following, and this code is read by the printer to control operation of the print head.
