    摘要： An inkjet printing device includes a print head for ejecting ink, a carriage provided with the print head detachably mounted thereon for moving the print head, an ink tank placed outside the carriage for storing ink, an ink supply path for supplying ink from the ink tank to the print head, and a discharge unit for discharging ink in the print head. Before the print head is detached from the carriage, the discharge unit discharges the ink in the print head.

    摘要： An ink jet printing apparatus includes a print head having an ejection port surface with ejection ports formed therein from which ink is ejected, a cap covering the ejection port surface of the print head, and a suction unit for allowing a pump to generate negative pressure in the cap to suck ink from the print head. The suction unit has a valve provided in a communication tube joining the pump and the cap together. The suction unit sucks ink under a relatively low negative pressure and then switches the valve to suck the ink under a relatively high negative pressure.

    摘要： There is provided an inkjet printing apparatus which can restrict each of coloring of reflected light and image clarity within an allowable range required in each of a color mode and a monochromatic mode in any of the modes to output an image with a high grade. For this end, a print duty of each of the first image improving liquid and the second image improving liquid is set in such a manner that a ratio of the print duty of the first image improving liquid having low penetratability to the print duty of the second image improving liquid having high penetratability is higher in the monochromatic mode than that in the color mode. Thereby, an appropriate ratio and an appropriate amount of appropriate kinds of the image improving liquids are applied to each of the color mode and the monochromatic mode.

    摘要： The present invention suppresses a bronzing phenomenon that occurs easily in inkjet printing that uses pigment ink, and minimizes other effects on the image quality by particularly minimizing the change in gray balance. Of at least first and second achromatic inks having different densities of pigment coloring material, the amount of resin in the second achromatic ink (light gray ink) having the lowest density of coloring material is increased, and on the achromatic color axis, a specified amount of light gray ink is used up to gradations other than highlighted areas, and light gray ink is printed in scans after all the inks that include the second achromatic ink. As a result, it is possible to reduce the bronzing phenomenon.

    摘要： An inkjet printing apparatus is provided which minimizes the amount of inks consumed for preventing the sedimentation of ejected inks on the platen ink absorber and which can effectively prevent the sedimentation of inks. To this end, a comparison is made between the ejected volume of easily sedimenting inks and the ejected volume of sedimentation restraining inks in terms of ink components. If the ejected volume of the sedimentation restraining inks is found not enough, a required amount of sedimentation restraining ink is additionally ejected.
