The invention describes an inkjet printer ( 1 ) with a printing bed ( 2 ) for displacing a print medium ( 3 ) in a forward feed direction ( 17 ) and a print head carriage ( 10 ) disposed above the printing bed ( 2 ) for displacing at least one print head unit ( 11, 32 ) in a transverse feed direction ( 15, 16 ), a print head unit ( 11, 32 ) with at least one print head ( 12 ) being provided for every colour to be printed, each print head ( 12 ) having at least one nozzle row ( 18 ) oriented in the forward feed direction ( 17 ) of the print medium ( 3 ). The nozzles ( 19 ) of the at least one nozzle row ( 18 ) of the print head unit ( 11, 32 ) are disposed offset from one another by a nozzle distance D ( 20 ) by reference to the forward feed direction ( 17 ). Another print head unit ( 31, 40, 41, 71 ) is provided, which has nozzles ( 34, 73 ) in at least one nozzle row ( 35, 72 ) disposed offset from one another by a second nozzle distance d ( 36 ) by reference to the forward feed direction ( 17 ) of the print medium ( 3 ), the ratio derived from the nozzle distance D ( 20 ) and the second nozzle distance d ( 36 ) being a ration al number and greater than 1.
