    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.

    摘要： An ink jet recording apparatus includes a recording head, an ink tank, and two ink routes. The recording head is mounted on a carriage moving along a recording surface of a recording medium and discharges ink and thereby performs recording on the recording medium. The ink tank is disposed inside the recording apparatus and stores ink to be supplied to the recording head. The two ink routes connect the ink tank and the recording head and are capable of circulating ink between the ink tank and the recording head. One of the ink routes is an ink supply path that supplies ink from the ink tank to the recording head, and the other ink route is an ink reflux path that returns ink from the head to the ink tank. The ink reflux path is capable of being fluidly connected to and disconnected from the recording head.

    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： When completing an image in a predetermined area by an odd or even number of bidirectional printing scans, this invention makes it possible to suppress lines of image defects and density variations and thereby print a high-quality image at high speed. In completing an image by an odd number of bidirectional printing scans, the print data for small ink droplets and large ink droplets are thinned using the first and second thinning pattern. The first and second thinning pattern thin the print data for small ink droplets and large ink droplets so that a difference between the total print ratio of all forward printing scans of the odd number of scans and the total print ratio of all backward printing scans of the odd number of scans when the first thinning pattern is used differs from that when the second thinning pattern is used.

    摘要： When a printing position is displaced by an inclination of a printing head, for example, the displacement can be corrected in an easy and effective manner and a user can easily recognize the displacement of the printing position to correct the displacement. To realize this, dots for forming a test pattern are formed by different scannings by a nozzle group including a plurality of nozzles positioned at one end side of a nozzle row and a nozzle group including a plurality of nozzles positioned at the other end side of the nozzle row. Depending on displacements of the printing positions of these dots, the plurality of nozzles constituting the nozzle row are divided into a plurality of divided nozzle groups. Then, the printing position is adjusted on the basis of the divided nozzle groups.

    摘要： An ink jet printing apparatus including a suction recovery function performs suction recovery that that recovers the reliability of a print head while reducing the amount of ink sucked from the print head. 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 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： Image deterioration is suppressed as much as possible which is complexly generated by variations of printing positions respectively of printing elements in a printing element row and by displacement of printing positions among printing element rows. To this end, a first adjustment value for adjusting printing positions among a plurality of printing elements included in a printing element row is obtained. Next, printing positions among a plurality of printing elements are adjusted based on the first adjustment value. Then a second adjustment value for adjusting printing positions among not less than two of the printing element rows is obtained. Thereby variations of printing positions in a discharge port row and displacement of printing positions among discharge port rows are properly adjusted in different phases, and adverse effects generated by two kinds of different causes are collectively suppressed.
