Abstract
The present invention provides a printing method comprising a selecting method of selecting defective print elements to be corrected on the basis of, for example, the positional relationship among the defective print elements in a print head so that if there are a plurality of defective print elements such as non-ejection nozzles, not all pixels otherwise printed by the defective print elements are to be corrected but efficient corrections can be achieved on the basis of correlations with the lifetimes of other normal print elements, as well as a correcting method of making up for print data corresponding to the defective print elements selected, and a printing apparatus using the printing method.
