Inkjet recording device and inkjet recording method

摘要

An inkjet recording device records images by forming dots on a recording medium with droplet modulating method. The inkjet recording device includes a recording unit, a multilevel-data creating portion, and a dot-layout-data creating portion. The recording unit ejects ink droplets for forming dots at corresponding pixel positions. The recording unit is capable of changing a volume of each ink droplet to form dots with different sizes. The multilevel-data creating portion creates multilevel data based on image data. The multilevel data includes a dot size for each dot. The dot-layout-data creating portion creating dot layout data based on the multilevel data, so as to prevent the recording unit from forming dots having the same size continuously by greater than or equal to a predetermined number. The recording unit performs recording operation based on the dot layout data.
