    摘要: A method for digitally printing on three-dimensional objects comprising bottles, cans or other hollow bodies, by at least one printing head, includes breaking down a printing template into a multiplicity of printing dots. The printing dots are stored in a printing raster consisting of image columns and image rows. The printing raster is used for activating the at least one printing head during a printing process in which one of the objects to be printed moves relative to the at least one printing bead in order to apply a print image onto the object to be printed. The printing raster Is curved and the image rows and the image columns extend obliquely to one another. The printing template is read into the curved printing raster.

    摘要: A device for ink supply during digital printing includes at least one print head having an inlet and an outlet. A feed tank for an ink medium is connected to the inlet of the at least one print head via a feed line. A return tank for the ink medium is connected to the outlet of the at least one print head via a return line. A gas volume is formed in the feed tank and/or in the return tank. The ink medium is convcyable through the at least one print head by a pressure of the gas voiume in the feed tank and/or in the return tank.
