An ink jet printing apparatus and method are provided which can satisfy in a well-balanced manner both an improvement of image uniformity and a reduction in glossiness variations. A plurality of print modes are prepared which include: a first print mode to perform a printing operation in a way that makes equal print ratios of the plurality of nozzle arrays; and a second print mode to perform a printing operation in a way that makes a print ratio of at least one of nozzle arrays situated at ends of the plurality of nozzle arrays smaller than print ratios of other nozzle arrays. The user selects from the plurality of print modes an appropriate one that strikes a balance between uniformity and glossiness and thereby can achieve a desired quality of image.

A width A of the scanning area of the ink ejection orifices and a width B of the scanning area of the reacting liquid ejection orifices are respectively set as A=(n−a)×p and B=n×p, while amount of the feeding of the printing sheet during each scan corresponds to the width of the scanning area of the reacting liquid ejection orifices, that is, A=(n−a)×p. With this system, the width of the scanning area, wherein ejection of the reacting liquid precedes ejection of the ink, is made shorter by C=a×p than the width of following scanning area; the scanning area having the width C is scanned two times by the row of the ink ejection orifices, and the thinning process is applied to this area having the width C.

An ink jet printing apparatus is provided in which ink absorbers, capable of performing their function to the fullest extent to quickly absorb an ink that tends to coagulate, are installed to prevent an interior of the printing apparatus and the back of a print medium from being contaminated. To this end, the printing apparatus has an ink absorber that contains a coagulation inhibitor capable of inhibiting the coagulation of colorant contained in the ink. This arrangement inhibits the coagulation of the colorant on the surface or in the interior of the absorber, allowing the colorant to be absorbed quickly and uniformly into the interior of the absorber. Therefore, problems caused by a deposition of the colorant on the surface of the absorber or by a degraded absorbing capability can be alleviated, thus keeping the image output in good condition.

Disclosed herein is an ink-jet recording process for conducting recording by ejecting a pigment ink and a reaction liquid containing a polyvalent metal salt from a recording section, in which a plurality of nozzles for ejecting the pigment ink and the reaction liquid are arranged, to a recording medium while relatively scanning the recording section to the recording medium, comprising the steps of ejecting the pigment ink having a surface tension lower than that of the reaction liquid to the reaction liquid ejected on the surface of the recording medium; and forming a filmy aggregate by gathering of agglomerates at an interface where the reaction liquid has come into contact with the pigment ink, wherein conditions for ejecting the reaction liquid to a prescribed area on the recording medium when at least the print duty of the ink in the prescribed area is 100% satisfy the relationship of 55 × 0.85 × 10 6 × Vd ( pl ) - 0.61 Rx ( dpi ) Ry ( dpi ) ≤ duty ( % ) ≤ 125 × 0.85 × 10 6 × Vd ( pl ) - 0.61 Rx ( dpi ) Ry ( dpi ) wherein Vd(pl) is an ejection volume per dot of the reaction liquid, Rx(dpi) is a print resolution in the direction of the relative scanning, Ry(dpi) is a print resolution in the arrangement direction of the nozzles, and duty(%) is a print duty of the reaction liquid.

A width A of the scanning area of the ink ejection orifices and a width B of the scanning area of the reacting liquid ejection orifices are respectively set as A =(n−a)×n p and B=n×p, while amount of the feeding of the printing sheet during each scan corresponds to the width of the scanning area of the reacting liquid ejection orifices, that is, A=(n−a)×p. With this system, the width of the scanning area, wherein ejection of the reacting liquid precedes ejection of the ink, is made shorter by C=a×p than the width of following scanning area; the scanning area having the width C is scanned two times by the row of the ink ejection orifices, and the thinning process is applied to this area having the width C.
摘要:
The present invention provides a method and apparatus for ink jet printing enabling a high grade image with the reduced ununiformity of colors to be inexpensively printed. A scan of a print head is executed to apply a reacting liquid to a print medium so that the number of reacting liquid dots impacting a unit area is reduced as the scan moves from a printing start-point of the reacting liquid to a printing end-point. Then, a scan of the print head is executed to apply the coloring inks to the area printed the reacting liquid. Simultaneously, the reacting liquid is applied to an area which precedes by one band the area printed coloring inks. Then, the coloring inks are applied. Simultaneously, the reacting liquid is applied to the area which precedes by one band the area printed coloring inks. An image is formed by repeating the above steps.
