Abstract
When image data is generated based on a drawing command by an inkjet printing apparatus which performs printing on a print medium with the use of an inkjet printhead discharging ink, an area of a graphic to be drawn is calculated based on the received drawing command, and it is determined whether or not the area exceeds a predetermined value, and whether or not a density value of the graphic exceeds a predetermined density value based on the drawing command. In accordance with the two determination results, the density value is converted, and image data is generated based on the converted apparatus value. Accordingly, occurrence of cockling can effectively be prevented without largely increasing a load imposed on hardware.
