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.

摘要： In an image printed by a printing apparatus, graininess particularly in a light part of the printed image is reduced by relatively simple structure by using a second color. To do so, magenta and cyan color component data in image data is subjected to under color removal to generate image data of a blue ink being the secondary color. On the basis of the data of the blue ink replaced for magenta and cyan, printing is performed by forming dots of the blue ink. At this time, black data is distributed into dark black and light black by density distribution, and the light black is substituted by the blue and yellow inks, whereby it is possible by the simple structure to prevent the graininess appeared when the cyan and magenta dots mutually appear biasedly and the graininess due to the black ink dots.

摘要： To provide an ink jet printing apparatus that can realize fast printing based on fast fixing and that can print high density black characters with little feathering and images with little bleeding at a boundary between colors. More specifically, a black ink is applied to a printing medium and a processing liquid is then applied to the black ink to mix the black ink and the processing liquid together on the printing medium in a liquid state. After reaction resulting from the mixture of the black ink and the processing liquid, color inks are applied to an area of the printing medium to which the black ink and the processing liquid are not applied. Accordingly, a reactant between the black ink and the processing liquid or the black ink becomes insoluble and thus is prevented from flowing out to peripheries of the image, thereby reducing bleeding at the boundary between a color image and a black image as may occur when the color ink is applied to the peripheries.

摘要： Disclosed are an ink-jet printing method and apparatus for jetting ink successively from nozzles of an ink-jet head at a prescribed frequency and forming each of a number of pixels by a plurality of dots conforming to the tone of the pixel. Each nozzle of the ink-jet head has a heater A and a heater B. Printing is performed by changing the number of heaters actuated to jet an ink drop, thereby to control the formation of a large or small dot by each nozzle, and by changing the method of driving the heaters A and B in dependence upon the density of the ink used. In regard to the timings at which the large and small dots are formed by each nozzle, the small dot is formed first. As a result, the large and small dots can be made to overlap so that an image having excellent tone reproducibility can be printed.
