Abstract: Inkjet printing equipment capable of measuring a droplet includes a process stage providing a processing space for a process substrate, a pair of guide members disposed on opposite sides of the process stage, a head unit discharging a droplet onto the process substrate, a first gripper moving along the pair of guide members and gripping a side portion of the process substrate, a second gripper configured to move along the guide members and gripping a measurement substrate onto which a droplet is discharged in order to inspect the head unit, and a droplet inspection unit inspecting a discharge state of the droplet discharged onto the measurement substrate and outputting information of whether the discharge state of the droplet is normal or abnormal.
