Abstract
Official abstract text for this publication.
In a printing device, printing is performed by relatively moving a nozzle array for ejecting a liquid droplet with respect to a print medium, a resolution by a nozzle pitch of the nozzle array is lower than a target print resolution, and between liquid droplets ejected by a single nozzle array, liquid droplets are ejected from the same or another nozzle array to attain the target print resolution. Each of a plurality of nozzles in the single nozzle array is printable by changing an ejection density by applying a preset rate thinning when ejecting liquid droplets by relatively moving with respect to the print medium. The printing device is provided with a print control part configured to perform printing by dividing the single nozzle array into a plurality of nozzle blocks and determining the ejection density in every nozzle blocks.
