Discharge rate control method for ink-jet printer, ink spread inspecting method, and oriented film forming method

Abstract

Discharge rate control method for ink-jet printer 1 including film forming step forming film B on coating article 2 with non ink-absorbent characteristic by discharging ink on coating article 2 from a plurality of nozzles 4 of print head 3, film thickness measuring step measuring film thickness of film B, corresponding to ink discharge position of each nozzle 4, formed on coating article 2 in film forming step, and discharge rate correcting step correcting discharge rate of ink from each nozzle 4 by increasing or decreasing discharge rate based on difference between target film thickness Ba and film thickness at ink discharge position of each nozzle 4 measured in film thickness measuring step.
