Abstract
A method of preventing image degradation due to nonejecting nozzles of a recording head is provided for an inkjet recording apparatus for recording images by ejecting ink from plural nozzles disposed in the recording head. The method according to the present invention includes the steps of measuring and recording a pattern for checking an ejection state of the head, determining a nonejecting nozzle from the pattern, obtaining density distribution for each nozzle, and determining a complementary table for every nozzle from the density distribution in the nonejecting nozzle portion for performing different-color complementing.
