Method for operating an inkjet printing apparatus

Abstract

A method for operating an inkjet printing device with at least one inkjet printhead having a row of nozzles through which ink can be directed onto the substrate to be printed, which is guided over a cylinder or over a curved guide element. The inkjet printhead or each inkjet printhead is oriented transversely to the transport direction of the substrate, so that the nozzles in the row of the inkjet printhead or of each inkjet printhead are different distances away from the substrate to be printed. To print the substrate, the nozzles in the nozzle row of the inkjet printhead or of each inkjet printhead are actuated in such a way that that the differences in the nozzle to substrate travel time caused by the different distances between the nozzles in each row and the substrate to be printed are equalized or compensated.
