Abstract
A liquid jet recording method of recording on a recording material with liquid droplets discharged trough plural scanning nozzles, in which: EQU n/(s/p).gtoreq.2 EQU n/(s/p).times.k=g-1 are satisfied, PA1 where n (n.gtoreq.2) is a number of the nozzles arranged at pitch P (.mu.m); s (.mu.m) is a distance of relative movement between the nozzles and the recording material between adjacent scans; k (k.gtoreq.1) is a maximum number of ink droplets per pixel and per scan; g (g.gtoreq.3) is a number of tone levels.
