Abstract
A method for reducing undesired variations of print density in a printed output is implemented by selectively increasing the number of drops of ink deposited in rows traveled by nozzles corresponding to a reduced-output region of the print head compared to the pattern of drops which would be deposited if all nozzles were operating normally.
