    摘要： A printer includes a print unit that ejects ink droplets of at least one ink color onto the sheet, at least one roller that feeds the printed sheet, and a controller that controls the print unit to print the sheet based on image data that defines an ink provision amount of each ink color for every dot according to a print resolution. The controller detects, based on the image data, a broad solid area, and carries out a print setting change with respect to the broad solid area by making the print resolution in the image data lower and making the ink provision amount of each ink color in the image data larger according to the print resolution that is made lower. According to the printer, stains on the printed sheet can be restricted.

    摘要： An inkjet printer includes a transfer unit that transfers a paper, a print unit that has three or more nozzle rows aligned along a transfer direction of the paper, and a controller that ejects ink on the paper by controlling the print unit while transferring the paper by controlling the transfer unit. The most-upstream nozzle row of the nozzle row and the most-downstream nozzle row are capable of ejecting ink whose color has a lowest brightness among colors of ink to be used for printing. The controller selects the most-upstream nozzle row or the most-downstream nozzle row as a nozzle row for ejecting the ink whose color has a lowest brightness according to a type of the paper. According to the printer, it becomes possible to restrict contaminations on a printed media while also restricting degradation of print quality.

    摘要： The method is a non-aqueous inkjet printing method including the steps of: ejecting droplets of a non-aqueous pigment ink containing at least a pigment and a non-aqueous solvent onto a surface of a printing medium to form dots composed of the non-aqueous pigment ink, and then ejecting droplets of a non-aqueous post-treatment liquid containing at least silica and an organic solvent toward the printing medium so that the droplets overlap with the dots composed of the non-aqueous pigment ink, wherein either of the non-aqueous pigment ink and the post-treatment liquid contains a water-soluble resin having an amino group.
