Method of compensating for a failed print nozzle of an inkjet printhead

Abstract

A method for compensation for a failed print nozzle of an inkjet printhead for the printing of a printed image onto a print material conveyed in a transport direction, includes printing the printed image with at least two different print droplet volumes, one of which is a maximum print droplet volume. At least one compensation nozzle, i.e. a neighboring nozzle of the failed nozzle, prints compensation droplets with an elevated compensation droplet volume compared to the maximum print droplet volume. A frequency for the creation of compensation droplets is defined, and the compensation nozzle is actuated such that the defined frequency is observed and the successive compensation droplets printed by the compensation nozzle have a defined minimum separation in the transport direction.
