Increased droplet placement accuracy in inkjet printing

摘要

The present invention relates to an inkjet print head ( 1 ) comprising at least one nozzle chamber ( 2 ), having a nozzle aperture ( 3 ) defined in one wall thereof for the ejection of printing fluid out of said aperture ( 3 ), and a printing fluid supply channel interconnected with said nozzle chamber ( 2 ). A printing fluid droplet tail release guide arrangement ( 4 ) is arranged at a predetermined position at an edge of a circumference of said aperture ( 3 ). The present invention further relates to a method for increasing droplet placement accuracy in an inkjet print head having at least one nozzle chamber with a nozzle aperture defined in one wall thereof for the ejection of printing fluid out of said aperture. The method comprises the step of providing a printing fluid droplet tail release guide arrangement at a predetermined position at an edge of a circumference of said aperture.
