Abstract

In a method for preventing or reducing air vortex formation between a print plate and a recording medium upon printing to the recording medium with a coating substance (e.g. primer), the recording medium is provided at a feed velocity of at least 20 meters per minute, and a plurality of print nozzles of a print head are alternately activated to print the coating substance on recording medium to cover a surface of the recording medium with the coating substance. The activation can include only activating a portion of the plurality of print nozzles simultaneously. Further, a predetermined applied quantity of the coating substance per area is constantly printed onto the recording medium.
