An inkjet printing apparatus includes: an array of inkjet heads; a set of heating elements each in a corresponding one of the inkjet heads and each configured to heat ink; an ink circulation route configured to circulate ink through the inkjet heads; an inlet thermometer configured to measure, as first temperatures, ink temperatures of ink each flowing into a corresponding one of the inkjet heads; an outlet thermometer configured to measure, as second temperatures, ink temperatures of ink each flowing out of a corresponding one of the inkjet heads; a heating unit configured to heat ink being circulated; and a controller configured to work with a temperature difference between a first temperature and a second temperature for each same inkjet head to determine allocation of an available power for heating ink to the heating elements and the heating unit.
