Inkjet printing apparatus

An inkjet printing apparatus comprising:

• a stage that supports a substrate;
• an inkjet head disposed above the stage and that ejects a first portion of ink on the substrate, the ink including solvent and solid particles dispersed in the solvent;
• an ink storage that stores the ink;
• a first link pipe that supplies the ink from the ink storage to the inkjet head, the first link pipe fluidically connecting the ink storage and the inkjet head to each other;
• a second link pipe that collects a second portion of the ink from the inkjet head and that supplies the second portion of the ink to the ink storage, the second link pipe fluidically connecting the ink storage and the inkjet head to each other;
• and
• a temperature controller including:
• a housing;
• a cooler supported in a first side portion of the housing;
• a heater supported in a second side portion of the housing;
• and
• a temperature adjustment member that absorbs heat from the cooler and radiates at least some of the heat to the heater, the temperature adjustment member being supported in the housing between the first side portion and the second side portion, wherein
• the second portion of the ink remains in the inkjet head after the first portion of the ink is ejected from the inkjet head on the substrate,
• the first link pipe is in thermal contact with the heater of the temperature controller, and
• the second link pipe is in thermal contact with the cooler of the temperature controller.
