ABSTRACT:
A liquid jet recording method for recording on a recording material with liquid droplets discharged through plural scanning nozzles arranged in a width measured in a direction of main scan. The recording method includes a first main scan by relative movement between the nozzles and the recording material, in which pixels are recorded with numbers of droplets through a nozzle, the numbers of droplets corresponding to respective tone signals. The method also includes a sub-scan by relative movement between the nozzles and the recording material in a direction crossing with a movement direction of the first main scan. The method further includes a second main scan in which the pixels are recorded with numbers of droplets through a different nozzle, the latter numbers of droplets corresponding to tone level signals. The sub-scan and second main scan steps are repeated to record a tone image by discharging plural droplets for a pixel.
