  • Printing machine with an inkjet printing head, a radiation drier and at least one light trap
    Patent number: 11548296
    Abstract: A printing machine includes an inkjet printing head having separately controllable nozzles for applying ink to a transported printing material, a radiation drier having radiation sources for generating electromagnetic radiation to at least partly dry and/or cure the applied ink on the transported printing material and at least one light trap disposed between the inkjet printing head and the radiation drier in such a way that the light trap forms a barrier for reflected and/or scattered radiation, thus protecting the inkjet printing head from radiation. The light trap includes at least one channel connected to an aspiration device for aspirating contaminated ambient air through the channel and reducing or preventing contamination of the radiation drier.
