The invention describes an inkjet printer with a printing bed for displacing a print medium in a forward feed direction and a print head carriage disposed above the printing bed for displacing at least one print head unit in a transverse feed direction, a print head unit with at least one print head being provided for every color to be printed, each print head having at least one nozzle row oriented in the forward feed direction of the print medium. The nozzles of the at least one nozzle row of the print head unit are disposed offset from one another by a nozzle distance D by reference to the forward feed direction. Another print head unit is provided, which has nozzles in at least one nozzle row disposed offset from one another by a second nozzle distance d by reference to the forward feed direction of the print medium, the ratio derived from the nozzle distance D and the second nozzle distance d being a rational number and greater than 1.

Inkjet printer

An inkjet printer with a printing bed for displacing a print medium in a forward feed direction and a print head carriage disposed above the printing bed for displacing at least one print head unit in a transverse feed direction, a print head unit with at least one print head being provided for every color to be printed, each print head having at least one nozzle row oriented in the forward feed direction of the print medium. The nozzles of the at least one nozzle row of the print head unit are disposed offset from one another by a nozzle distance D by reference to the forward feed direction. Another print head unit is provided, which has nozzles in at least one nozzle row disposed offset from one another by a second nozzle distance d by reference to the forward feed direction of the print medium, the ratio derived from the nozzle distance D and the second nozzle distance d being a rational number and greater than 1.

An inkjet printer with a print head carriage is disposed above the printing bed for displacing a print head unit in a transverse feed direction, a print head unit with at least one print head being provided for every color to be printed and having at least one nozzle row oriented in the forward feed direction of the print medium. Another print head unit is provided for applying white ink, whereby the row length of the color print head unit and the row length of the other print head unit at least partially overlap with one another, and whereby of the nozzles of the nozzle row of the color print head unit, only those nozzles lying outside of the overlap region between the row length of the color print head unit and the row length of the other print head unit activated for applying white ink are activated.
