Abstract
An inkjet print apparatus includes a print head discharging ink onto a substrate, the print head including a first heater; a reservoir storing the ink; a first pipe supplying the ink to the reservoir; a second pipe collecting surplus ink; a mixing unit located on the first pipe and mixing the ink; a pump located on the second pipe and pressurizing and supplying the surplus ink to the reservoir; a temperature sensor located between the mixing unit and the print head and sensing a temperature of the ink; and a controller controlling a temperature of at least one of the first heater and the second heater in response to information received from the temperature sensor. The print head includes a heat insulator blocking heat emitted from the first heater between the substrate and the first heater.
