INK JET PRINTER DISCHARGE AMOUNT CONTROL METHOD, INK DROPLET SPREAD CHECK METHOD, AND ORIENTATION FILM FORMATION METHOD

摘要

A discharge amount control method for an ink jet printer (1) includes: a film formation step for discharging ink onto an ink non-absorbing material-to-be-coated (2) from a plurality of nozzles (4) of a print head (3) so as to form a filmB on the material-to-be-coated; a film thickness measurement step for measuring the film thickness of the film B formed on the material-to-be-coated (2) in the film formations step in connection with the ink discharge position of each of the nozzles (4); and a discharge amount correction step for increasing/decreasing the ink discharge amount from each of the nozzles (4) according to the difference between the film thickness at the ink discharge position of each of the nozzles (4) measured in the film thickness measurement step and a target film thickness Ba.
