Abstract
Official abstract text for this publication.
Provided is a liquid droplet discharging method including: based on a first correction quantity table correlating to discharging of the first nozzle row, a second correction quantity table correlating to discharging of the second nozzle row, a relative usage ratio of the first nozzle row to the second nozzle row (=a usage rate of the first nozzle row/a usage rate of the second nozzle row), and a third correction quantity table correlating to discharging of a predetermined value Hk which is the relative usage ratio, correcting a liquid droplet quantity, per a unit area in print media, discharged from the first nozzle row and/or the second nozzle row.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid droplet discharging method, comprising: providing a printer with a transport action where a print medium is moved in a transporting direction, and with a liquid droplet discharging scan action where a first print head and a second print head move and discharge liquid droplets onto the print medium in a scanning direction intersecting the transporting direction, said first print head having a first column of liquid-discharging nozzles lined up in the…
