Abstract
A discharge rate control method for an ink-jet printer (1) includes forming a film (B) on a coating article (2) having a non ink-absorbent characteristic. Ink is discharged on coating article (2) from a plurality of nozzles (4) of a print head (3). The film thickness of film (B) is measured, corresponding to ink discharge positions of each nozzle (4). The discharge rate of ink is corrected for each nozzle (4) by increasing or decreasing the discharge rate based on differences between a target film thickness (Ba) and a film thickness at an ink discharge position of each nozzle (4).
