Pochner, K.K.Pochner2022-03-082022-03-081999https://publica.fraunhofer.de/handle/publica/304200The fixing stage (2) follows the ink jet head (1) in the printing sheet transport direction, for fixing the applied ink using a photochemical reaction, activated by a switched UV light source (2), e.g. an excimer lamp. Pref. the switching of the UV light source is synchronised with the operation of the printer, the printing ink containing a photo-sensitive component acting as a polymeriser, with full absorption of the spectral output of the UV light source. Alternatively the fixing stage may use cooperating discharge electrodes on opposite sides of the sheet feed plane, with the ink containing a polymerisable component responsive to the electrical discharge.
