PROBLEM TO BE SOLVED: To provide a method for delivering ink capable of preventing deterioration of image quality caused by deviation of depositing positions of a main droplet and a sub-droplet. SOLUTION: The main droplet of ink droplets delivered from a printing head 22K1 is represented by K1m and the sub-droplet delivered therefrom is represented by K1s. In the similar way, the main droplet of the ink droplets delivered from the printing head 22K2 is represented by K2m and the sub-droplet delivered therefrom is represented by K2s. In this case, a raster L1 is constituted of the main droplets K1m of the ink droplets delivered from a plurality of nozzles on the printing head 22K1. One main droplet K1m forms one pixel and the raster L1 is constituted of a plurality of the main droplets K1m arranged in the lateral direction. Similarly, a raster L2 is constituted of the main droplets K2m. A raster L3 is constituted of the sub-droplets K1s and the sub-droplets K2s. One pixel is formed of one sub-droplet K1s and one sub-droplet K2s (i.e., two sub-droplets K1s and K2s). COPYRIGHT: (C)2007,JPO&INPIT |
