ABSTRACT:
The improved back printing apparatus for recording a back print on a non-exposed surface of a light-sensitive material to be subjected to wet photographic processing comprises a charging section to be charged with an ink which is heat-fusible but solid at ordinary temperatures and which is not water-soluble; a melting section for melting the ink; and a print head from which the ink melted in the melting section is jetted to record the back print. Using this back printer, one can produce sharp back prints of high quality without causing any adverse effects on the light-sensitive material A and yet good handling properties are assured.
