| description | It is an object of this invention to provide an inkjet printing apparatus that can print an image with high uniformity in image clarity and gloss level irrespective of the gradation value of the image. The print head of this invention can eject color inks and an image quality improvement liquid that changes at least the gloss level or image clarity of the image. The print head scans over same print areas of a print medium to form an image and at the same time applies the image quality improvement liquid onto the image. A control unit raises the volume of the image quality improvement liquid applied to unit areas in a relatively subsequent scan to the volume of the image quality improvement liquid applied to unit areas in a relatively preceding scan at a rate that corresponds to the volume of the color ink applied to the unit areas. |
