Liquid ejecting control method and liquid ejecting apparatus

摘要

There is provided a liquid ejecting control method for outputting an image without an influence of ejection amount variations. Therefore among a plurality of drive modes in which an amount of liquids ejected from one nozzle is different from each other, control information indicating a drive mode to be associated is obtained, and a drive signal to an individual pixel is generated according to the control information and image data that is input for each pixel. The control information sets a drive mode in which an ejection amount closer to a target ejection amount is obtained, among the plurality of drive modes. In addition, a difference between the target ejection amount and the ejection amount to be realized in the set drive mode is found, and this difference is used to correct a target ejection amount of the other pixel in which the drive mode is not set yet.

1. A liquid ejecting control method for ejecting liquids from a plurality of nozzles comprising:
a step for obtaining control information indicating one drive mode to be associated among a plurality of drive modes in which an amount of liquids ejected from one nozzle is different from each other; and a drive signal generating step for generating a drive signal to an individual pixel according to the control information and image data that is input for each pixel, wherein the control information is preliminarily set according to a control information setting method including: a step for obtaining a plurality of ejection amounts corresponding to the plurality of drive modes in regard to each of the plurality of nozzles; a setting step for, in regard to one pixel, setting one drive mode out of the plurality of drive modes by comparing the plurality of ejection amounts of the nozzle corresponding to the pixel with a target ejection amount set to the pixel; a difference obtaining step for finding a difference between an ejection amount corresponding to the drive mode set by the setting step and the target ejection amount; and an adjusting step for adjusting a target ejection amount to the other pixel to which the drive mode is not set, based upon the difference.
