  • Publication number: 20240100821
    Abstract: In a method for printing a digital image in swaths with a swath time corresponding to the width of the digital image on the image receiving medium in the main scanning direction, the print controller issues a trigger that a spitting action for at least part of the printing elements of the print head needs to be performed. A swath time of subsequent swaths is gradually increased until the print head reaches a maintenance tray at a side of the print surface. The print head stays at the maintenance tray until air between the print head and the maintenance tray has approximately reached a standstill. Then, at least part of the printing elements of the print head are spitting marking material in the maintenance tray. After the spitting, the swath time of subsequent swaths is gradually decreased until the swath time is corresponding again with the width of the digital image on the image receiving medium in the main scanning direction. A digital inkjet printer is configured to perform the method.
