PURPOSE: Inkjet printing apparatus and method are provided to significantly enhance the yield of substrates since the process parameter of a mother board is determined using a separate recyclable test substrate. CONSTITUTION: An inkjet printing apparatus comprises a gantry unit(100), an auxiliary process unit(300), a main process unit(200) and a controller(400). A plurality of inkjet heads for the materials of R, G, B color filters, and a camera are movably installed along an x-axis on the gantry unit. The auxiliary process unit is added under the gantry unit in a test process and comprises a test substrate and a backlight unit. While being transferred along a y-axis, which crosses the x-axis, the test substrate receives a color filter for test based on the test parameter. The backlight unit is arranged under the test substrate. The main process unit is added under the gantry unit in the main process. The controller controls the discharging of the inkjet head using the test parameter.
