Abstract
In an inkjet printing apparatus which generates satellites droplets, problems in an image attributable to the satellites are mitigated as far as possible. For this purpose, each parameter is adjusted to satisfy a relationship such that the distance between positions of placement of a main droplet and a satellite substantially agrees with an integral multiple of the width of an index pattern. As a result, a satellite is likely to be placed in a position overlapping a dot formed by a main droplet printed in the same area of a pixel located in the vicinity of the satellite, which prevents satellites from placement blank positions where no dot should be printed. Thus, the influence of satellites is mitigated, and problems in an image attributable to satellite are reduced.
