摘要： In a method of cleaning an ejection face by supplying a head liquid on a surface (ejection face) of an inkjet head provided with ink ejection outlets, and then by performing wiping operations thereon, an ink residue on the ejection face is efficiently and surely removed from the ejection face to achieve a sufficient cleaning thereon. For this purpose, a first wiping operation is first performed such that a wiper (9A) is relatively largely bent, and slidingly contacts the ejection face at an abdomen thereof to efficiently perform the application, stirring and mixing of the head liquid. Then, a second wiping operation is performed such that an edge portion of the top end of a wiper (9B) slidingly contacts the surface to efficiently scrape the mixture of the head liquid and the ink residue.

摘要： An ink jet recording apparatus is provided that changes the adjustment temperature of a recording head depending on the number of recording media so that a favorable recording result can be maintained for any number of recording media and a time required for the recording can be reduced. Different adjustment temperatures T2 are used depending on the number of recording media. When the number of recording media is relatively small, T2 is determined to be low and, when the number of recording media is relatively large, then T2 is determined to be high. When the recording is started, when the head temperature is lower than the determined temperature T2, then ink is heated by a sub heater. Depending on the determined temperature, an interval with which a preliminary ejection is performed is changed.

摘要： An ink jet printing method and apparatus using a color ink and a print performance improving ink which minimizes an image quality degradation due to blank lines formed by failed or faulty nozzles. This system enables the use of a print head even with failed or faulty nozzles by minimizing the image quality degradation and extends the life of the print head before replacement. The print performance improving ink is deliberately ejected onto a blank line or its vicinity to produce the so-called primer effect, thereby inducing the color ink dots on the lines adjoining the non-ejecting nozzle line to spread into the blank line to make the blank line undistinguishable.

摘要： High quality images showing an excellent fixation are formed by an ink-jet recording method using pigment inks. An ink set for the ink jet-recording method comprises a first ink containing an anionic dye in an aqueous medium, a second ink containing an anionic dye and having a lower coloring material content than the first ink and a dispersion destabilizing substance, and a third ink containing a self-dispersible first pigment, a second pigment and a polymeric dispersant for dispersing the second pigment in an aqueous medium. The dispersion destabilizing substance destabilizes the dispersion stability of at least either the first pigment or the second pigment in the third ink when the second ink and the third ink are brought into contact with each other. The second ink and the third ink are applied onto a printing medium one after another or substantially simultaneously so that they are brought into contact with each other in a liquid state on the printing medium.

摘要： There are provided a plain paper mode in which printing is performed on a plain paper and a special medium mode in which printing is performed on a special printing medium having a coat layer formed thereon. In the plain paper mode, Bk ink using both self-dispersing type pigment and dye as coloring materials is ejected from a Bk head, then a processing liquid with a high penetrability which insolubilizes the above coloring materials is ejected from a S head. On the other hand, in the special medium mode, the above Bk ink is ejected from the Bk head, but no processing liquid is ejected from the S head. As a result, this enables the improvement in a print quality, such as OD level, and a high-speed fixing in ink-jet printing in either case where a printing medium having a coat layer formed thereon is used or where the plain paper is used.

摘要： An ink which includes a first pigment, a second pigment, a polymer dispersant and an aqueous medium; wherein the first pigment is a self-dispersing pigment having on its surface at least one anionic group bonded to the surface directly or via an atomic group, the second pigment is dispersed in the aqueous medium by the polymer dispersant, and the polymer dispersant contains benzylmethacrylate as a monomer unit, or the polymer dispersant contains benzylmethacrylate as a monomer unit. Diffusion of this ink in the printing medium is suppressed in the cross-sectional direction but not horizontal direction. Thus, the ink can form an ink dot that has a proper dot size, uniform and high density in the dot, with little feathering or blur.
