Abstract
An ink jet printing method and apparatus using a color ink and a print performance improving ink which minimizes an image quality degradation due to blank lines formed by failed or faulty nozzles. This system enables the use of a print head even with failed or faulty nozzles by minimizing the image quality degradation and extends the life of the print head before replacement. The print performance improving ink is not ejected and landed near a blank line, thus allowing the color ink dots near the blank line to spread and thereby making the blank line undistinguishable.
