Bogendrucker mit einer Bogentransportanordnung (33A, 33B) zum Transportieren eines Bogens in einer Transportrichtung (X) entlang einer Druckstation (39) zum Drucken eines Bildes auf den Bogen sowie entlang eines Detektors (31), der stromabwärts der Druckstation (39) angeordnet ist zum Inspizieren des bedruckten Bogens, dadurch gekennzeichnet, dass eine Gebläseanordnung (60, 70) stromabwärtes des Detektors (31) vorgesehen ist, zum Erzeugen eines Luftstromes zwischen der Bogentransportanordnung (33A, 33B) und dem Detektor (31), welcher Luftstrom entgegen der Transportrichtung (X) stromaufwärts gerichtet ist. A method for inkjet printing of sheets (41), comprising the steps of: - conveying a sheet (41) along a print station (39) forjetting an image on said sheet (41); - drawing in air from the print station (39), filtering said air, and providing said air to an air blowing assembly (60, 70) positioned downstream of a detector (31) which detector (31) is positioned downstream of the print station (39) for inspecting sheets (41) printed by the print station (39); and - generating an air flow which flows from the air blowing assembly (60, 70) substantially upstream against the transport direction (X) underneath the detector (31) towards the print station (39). The upstream air flow prevents ink particulates originating from the print station (39) from contaminating the detector (31).
