Abstract
An inkjet printer assembly for printing an image on a recording medium comprises a medium support surface for supporting a recording medium; an inkjet print head for ejecting droplets of an UV-curable ink on the recording medium, the inkjet print head being arranged over the medium support surface; an UV radiation source for irradiating the droplets of UV-curable ink on the recording medium, the UV radiation source being arranged over the medium support surface; a covering arranged over the medium support surface, the covering and the medium support surface together enclosing a print space including the inkjet print head and the UV radiation source; and exhaust means, the exhaust means being configured to vent the print space. The covering comprises a window part arranged such to allow a view on the medium support surface, the window part being at least partially transparent for visible light and configured to filter UV radiation from the UV radiation source to an extent that no harmful amount of UV radiation passes through. Thus, an operator is enabled to view a print result directly as it is printed without being subjected to harmful radiation.
