Method for controlling droplet discharge head, drawing method, and droplet discharge device

A method for drawing, comprising:

• (a) pressurizing the portion defining the cavity with a pressurizing part of a droplet discharge head;
• (b) discharging a functional liquid from a nozzle communicating with the portion defining a cavity to a work;
• and
• one of (c) cleaning the nozzle, (d) measuring a discharge amount of the functional liquid discharged from the nozzle, and (e) waiting without discharge the functional liquid, wherein
• in a case where the functional liquid is not discharged from the nozzle, the pressurizing part pressurizes the portion defining a cavity a plurality of times in succession with a different frequency between the steps (a), (b) and the steps (c), (d), (e) so as to change pressure on the functional liquid at an extent not discharging the functional liquid from the nozzle.

A method for drawing, comprising:

• pressurizing a portion defining a cavity with a pressurizing part of a droplet discharge head;
• discharging a functional liquid from a nozzle communicating with the portion defining a cavity to a work;
• and
• pressurizing the portion defining a cavity a plurality of times in succession with the pressurizing part at an extent not discharging the functional liquid from the nozzle so as to change pressure on the functional liquid in a case where the functional liquid is not discharged from the nozzle, wherein
• the pressurizing part pressurizes the portion defining a cavity with a high frequency of variation of pressure for pressurizing the portion defining a cavity when the droplet discharge head is positioned where a wind-velocity is high, compared to a frequency of variation of pressure for pressurizing the portion defining a cavity when the droplet discharge head is positioned where the wind-velocity is low.
