Abstract
In a method to clean nozzles and ink channels of at least one ink print head with a flushing medium in an ink printing apparatus, a necessary flushing quantity of the flushing medium that is to be provided and which is necessary for flushing of the ink print head in a flushing process is determined from either a predetermined flushing quantity predetermined depending on a print duration of the ink printing apparatus or from a drive flushing quantity derived from a flushing quantity curve that indicates a dependency of the flushing quantity on an elapsed time for an ink used in printing, the necessary flushing quantity being either said predetermined flushing quantity or the derived flushing quantity, whichever is greater. The determined necessary flushing quantity is used to flush the ink print head.
