Abstract (en)

The ribbon includes two ink layer types. The ribbon comprises a film (1) supporting a layer of printing ink (2) and a detection layer (3). The detection layer is intended to block radiation of a given wavelength to which the ink layer is transparent. This detection layer comprises an intermediate ink layer (3) which is opaque to the wavelength in question. The detection layer lies between the supporting film (1) and the first mentioned ink layer (2). In an alternative arrangement, the supporting ribbon may be tinted in order to render it opaque to the radiation in question.
