Abstract
A method is provided for controlling the ejection of ink drops from an inkjet printhead. The printhead comprises an array of ink chambers with nozzles arranged for applying a row of ink dots on a receiving medium using a control signal. The method comprises the steps of labeling a nozzle as a functioning nozzle if the nozzle, upon activation by a control signal, ejects an ink drop within predefined specifications, otherwise labeling the nozzle as a failing nozzle, and distributing a control signal associated with a failing nozzle to a neighboring nozzle to maintain a local optical density, wherein said control signal associated with a failing nozzle is not distributed to a neighboring nozzle, if a neighboring nozzle of said failing nozzle is also labeled as a failing nozzle.
