The disclosure relates to a method for avoiding contamination of a printing plate given surface-covering coating of a dust-forming recording medium (e.g. an uncoated paper) with a coating substance (e.g. a primer) in an inkjet printing operation. The method can include feeding the recording medium at a feed velocity that is greater than 20 meters per minute; continuously printing of the coating substance onto the recording medium by at least one print head including a plurality of print nozzles, the coating substance being printed at a constant, predetermined applied quantity per area. A nip between the print head and the recording medium is provided such that a fluid-dynamic eddy is created between the recording medium and the print head and/or the printing plate. The disclosure also related to a printing system that is configured to implement the method.
