Abstract
Provided is an inkjet printing apparatus that, when performing multi-pass printing using pigmented ink and image enhancing liquid for adjusting the glossiness, is capable of outputting a high-quality image in which gloss unevenness due to displacement of the printing position cannot be noticed. In order to accomplish this, dot arrangement data is generated based on input image data so that the dot arrangement of image enhancing liquid includes a greater low-frequency component in the spatial frequency than the dot arrangement of colored ink on a print medium. As a result, it is possible to suppress gloss unevenness even when printing position displacement occurs, while at the same time suitably suppressing a feeling of graininess in colored ink.
