Abstract:
A liquid jet recording method of recording on a recording material with liquid droplets discharged through plural nozzles disposed in a width in a sub-scan direction, comprising the steps of:performing a first main scan operation by performing relative movement between the nozzles and the recording material and recording a plurality of pixels using a number of ink droplets ejected by a first nozzle corresponding to respective tone signals; performing a sub-scan operation by performing relative movement between the nozzles and the recording material in said sub-scan direction, said sub-scan operation effecting relative movement between the nozzles and the recording material by a distance smaller than the width; and performing a second main scan operation by performing relative movement between the nozzles and the recording material and recording a plurality of pixels using a number of ink droplets by a second nozzle corresponding to respective tone signals, wherein a plurality of pixels having plural tonal levels are formed on the recording material, and at least one of the plurality of pixels is formed by one ink droplet and others of the plurality of pixels are formed by plural ink droplets of a same color and a same nominal volume but different actual volumes.
