PROBLEM TO BE SOLVED: To provide a method for adjusting the discharge of droplets of a droplet discharge head which is installed in a pattern forming device and improves the stability of the discharge of the droplets discharged from the droplet discharge head. SOLUTION: A temperature sensor SE measuring the temperature of a functional liquid in the droplet discharge head 40 is attached to each carriage, the temperature at predetermined time is measured, and the detection signal is outputted to a control device 100. The control device 100 obtains the temperature every time from the detection signal of the temperature sensor SE. The temperature and flow rate of air supplied so that the temperature of the functional liquid in the droplet discharge head 40 is a predetermined standard temperature to drive/control an air supply device 125. A driving voltage value Vh where the discharge is a standard discharge at the time is obtained, and the driving waveform signal COM of the driving voltage value Vh is produced in a driving waveform production circuit 107 and outputted to a head driving circuit 108. The head driving circuit 108 drives each piezoelectric element PZ from the inputted driving waveform signal COM. COPYRIGHT: (C)2009,JPO&INPIT |
