Abstract

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.

Description

technical field

[0001] The present invention relates to a technique for maintaining the consistency of the ejection rate of ink on an application from a plurality of nozzles on a printhead of an inkjet printer among the individual nozzles, a technique for checking ink scatter And a technique for forming an alignment film on a glass substrate using this ink. Background technique

[0002] In recent years, in addition to printing on substrates made of paper, fibers, plastics, ceramics, etc. Inkjet printers are also used when coating color filters on transparent glass substrates in organic EL display devices. Specifically, in the case of a liquid crystal display device, an alignment film material such as transparent PI ink (transparent polyimide ink) or transparent UV ink is discharged and coated on a glass substrate (for example, see Patent Document 1), as far as In the case of an organic EL display device, a coating material such as transparent UV ink is discharged and coate...
