Inkjet printing apparatus

An inkjet printing apparatus comprising:

• a transport unit that transports a base material in a transport direction;
• an inkjet unit that ejects inks in a plurality of colors to said base material being transported by said transport unit;
• a printing controller that controls said inkjet unit on the basis of image data to print an objective image expressed by said image data on said base material;
• a drying unit located on a downstream side of said transport direction with respect to said inkjet unit, the drying unit applying an infrared ray to said base material to dry an ink ejected to said base material;
• a temperature sensor that measures a temperature at a measurement target region in said base material applied with said infrared ray;
• and
• a monitoring part that monitors the temperature at said measurement target region measured by said temperature sensor, wherein
• said measurement target region for said temperature sensor has infrared absorbance greater than an average value of infrared absorbance expressed by said image data.
