Abstract
The invention relates to a fluid ejection system comprising a print head unit including a fluid ejection nozzle array, wherein the fluid ejection nozzle array comprises at least a first set of nozzles having nozzles of a first fluid ejection capacity and a second set of nozzles having nozzles of a second fluid ejection capacity and nozzles of a third fluid ejection capacity, wherein the first fluid ejection capacity, the second fluid ejection capacity and the third fluid ejection capacity are different from one another, and further including a printer controller which, in a first printing mode, selects nozzles of the first and second sets for firing in proportions so that the overall color densities generated by the nozzles of second set when compared to nozzles of the first set are the same in a defined print area.
