Abstract
Disclosed is an inkjet print apparatus in which a printhead capable of printing utilizing ink of at least one color is mounted on a carriage and the carriage is caused to move across a printing medium to print an image on the printing medium, comprising: a head temperature detector for detecting temperature of the printhead; a dot counter for counting number of dots, which are formed in divided areas, per each divided area obtained by dividing an area of the printing medium into a plurality of areas in prescribed units; a comparator for comparing a threshold value, which corresponds to printhead temperature information that has been detected by the head temperature detector, and a count value representing the number of dots counted by the dot counter; and a decision unit for deciding, based upon result of the comparison performed by the comparator, a drive frequency for driving the printhead and a moving speed of the carriage; wherein printing of an image on the printing medium is performed at the drive frequency and moving speed decided by the decision unit.
