ABSTRACT:
When degree of a streak of density fluctuation is varied mainly due to variation of a printing medium to be used and/or variation of use environment of an apparatus to be impossible to correct the density fluctuation, a test pattern is first output with maintaining a second image correcting portion for correction inoperative. A correction coefficient of an image signal corresponding to ink ejection openings at end portions is then set depending upon density fluctuation .DELTA.C.sub.SUM on the ink ejection openings at the end portions obtained from the result of reading. By this, in an ink jet printing apparatus, the streak in a printed image can be constantly restricted irrespective of variation of the printing medium to be used and/or use environment of the apparatus.
