    摘要: The disclosure relates to a printing device for printing containers with at least one printing plane. At least one print head for applying ink to the container and at least one extraction device associated with the print head for extracting printing mist are arranged in each printing plane along an outer circumference of a free space which is designed to receive a container to be printed. The at least one print head and the at least one extraction device associated therewith are at a spacing from one another along the outer circumference. The disclosure further relates to an extraction device for extracting printing mist for use in the printing device, wherein the extraction device comprises an extraction tube, an extraction nozzle, and a connection device.

    摘要: Direct printing method for printing on a container having a print image by means of a direct printing device comprising a direct printing head with at least one printing nozzle row and an ink mist extraction unit, wherein a pixel offset is determined for at least one pixel of a print template for the print image based on a model for a print deviation from a normal pressure value caused by the ink mist extraction unit along the printing nozzle row, wherein a corrected print template is generated based on the determined pixel offset, wherein the print image is applied to the container by means of the direct printing device based on the corrected print template.
