Patent ID: 6851780

Claim:
A patterning method comprising the steps of: preparing a liquid discharge head comprising a discharge port for discharging liquid, a pressure-applying portion communicating with the discharge port, for applying a pressure for discharge to liquid, and a pressure-generating device for generating the pressure; and applying liquid to a liquid-receiving member supported on a support by driving the liquid discharge head, wherein said step of applying liquid comprises a step of applying a first discharge pulse for discharging liquid and a second discharge pulse for discharging liquid to the pressure-generating device in a sequential manner in response to an instruction of one-dot discharge, and wherein a pulse width T 1 of the first discharge pulse, a pulse width T 2 of the second discharge pulse, and a rest time K 12 between the first discharge pulse and the second discharge pulse are determined so that a first amount of liquid discharged in response to the first discharge pulse has a volume equal to or greater than that of a second amount of liquid discharged in response to the second discharge pulse and a discharge speed of the first amount of liquid is lower than a discharge speed of the second amount of liquid.
