Image output apparatus, image output method, ink jet print method and printed product obtained with said method
 An apparatus for performing the printing by scanning a carriage having a plurality of print heads mounted in a predetermined direction relative to the printing medium, so that an image is formed to have a desired color tone and density without decreased throughput. Conversion data for reproducing the color tone and the scan range of the carriage are changed in accordance with the used heads among the mounted heads. Also, the replaceability can be enhanced and the longer life for each group is attained by grouping the heads mounted. Further, the scan range of recording and the scan range for the recovery can be changed by selecting the group for use in accordance with the recording mode. Also, in an ink jet printing apparatus having a longer print length, a printing method for effecting the stable recording is provided.
