Abstract: In a print head, a plurality of ejection ports for ejecting metallic ink, including a solvent and particles for imparting a metallic gloss, are arranged in a predetermined direction. A plurality of printing scans are performed to the same area of the print medium to print an image on the print medium. In the printing scan, the metallic ink being ejected from the print head to a print medium while moving the print head in a scanning direction intersecting the predetermined direction. At least one of the plurality of printing scans is set as a first scan having a higher print ratio than the other printing scans.

Abstract: In a first printing step, metallic ink is applied to a color metallic area where a color metallic image on a print medium having a receiving layer containing a dye coagulating agent for coagulating a dye is formed, while moving the print head in a main-scanning direction. In a conveyance step, a print medium is conveyed by a predetermined distance in a conveyance direction crossing the main-scanning direction, after the first printing step. In a second printing step, a first color ink is applied to the color metallic area while moving the print head in the main-scanning direction. an application time difference until application of the first color ink to the color metallic area in the second printing step after application of the metallic ink to the color metallic area in the first printing step is included in a target range regardless of the image data.

Abstract: Ink containing metal particles is ejected from a print head, in accordance with a plurality of print ratios corresponding to a plurality of scans of the print head relative to a unit region of a print medium. At least one of the plurality of print ratios is set as a high print ratio which is higher than others. A height of the high print ratio, in a case where a scan corresponding to the high print ratio is a Lth (L: integral number) scan in the plurality of print scans, is higher than a height of the high print ratio, in a case where a scan corresponding to the high print ratio is a Nth (N>L; N: integral number) scan in the plurality of print scans.

Abstract: An image processing apparatus sets a threshold value matrix for each of multiple color materials, and uses the set threshold value matrix to acquire a first threshold value. On the other hand, the image processing apparatus sets reference data on the basis of multivalued data of that color material. Then, the image processing apparatus calculates a second threshold value matrix by performing a predetermined process on the first threshold value on the basis of the reference data for that color material. Further, by comparing the second threshold value with the multivalued data, quantization data for printing a dot is generated. When doing this, the threshold value matrix and the reference data for that color material are set so as to make the graininess of a dot pattern of that color material lower than the graininess of a mixed color dot pattern obtained by mixing dot patterns of the respective multiple color materials.
