Abstract

A method of accounting for dead nozzle remapping in a multi-nozzle printhead, including remapping a fixative intended for a dot to be printed by the dead nozzle.

Claims (7)

1. A method of accounting for dead nozzle remapping in a multi-nozzle printhead, the method including:

remapping a fixative intended for a dot to be printed by the dead nozzle; and

determining a first fixative plane and a second fixative plane using dead nozzle compensation and a color plane requiring the fixative;

whereby, the first fixative plane is initially used to supply the fixative to the printhead, but if the first fixative plane includes a dead nozzle then the second fixative plane is used.

2. The method according to claim 1 , wherein the remapping includes remapping the fixative to an operative nozzle to which dot data intended for the dead nozzle for printing at or adjacent a position at which the dead nozzle would have printed.

3. The method according to claim 1 , wherein the remapping includes preventing output of the fixative onto the position where the dead nozzle would have printed a dot had it been operative.

4. The method according to claim 1 , wherein the fixative defined by the first fixative plane and the second fixative plane is a multi-part fixative.
