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. 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： Upon performing printing using a dye ink and a pigment ink and in addition a treatment liquid making those inks insoluble, two kinds of inks consisted of the pigment ink and the dye ink are used. After applying the pigment ink on a printing medium, the dye ink is applied overlaying with the pigment ink. After mixing these inks on the printing medium, the treatment liquid which makes the inks insoluble, is applied. In the alternative, a mixed ink in which a pigment ink not requiring a dispersant and the dye, is used. After application of this mixed ink on the printing medium, the treatment liquid which makes the ink insoluble, is applied. Therefore, problem of “crack”, “soaking out”, “overflow” or lowering of OD value which can be caused upon reaction of the pigment ink and the dye ink or the mixed ink with the treatment liquid, can be solved to achieve high quality printing.

摘要： A method for adjusting an amount of discharge is to adjust the amount of liquid between liquid discharge units to discharge the liquid by driving a plurality of electrothermal transducing elements, which uses a plurality of liquid discharge units arranged corresponding to each liquid path for the creation of air bubbles for discharging the liquid, at the same time, being arranged to be capable of being driven individually. This method comprises the step of variably controlling the starting time of driving signal applied to each of the electrothermal transducing elements for the creation of air bubbles in each of the discharge units. The variable control thereof makes it possible to suppress the variation of discharge amount of liquid between the liquid discharge units, hence maintaining the amount of liquid discharged from each of the discharging units at a constant level to obtain printed images of higher quality.

摘要： In ink-jet printing, in order to improve fixation without using a means such as a heater, etc. even in the case of using an ink with a slow penetration speed, black ink discharged from one head is made to be relatively low penetrative, while a processing solution, which is discharged from the other head and insolubilize dye of the above black ink, is made to be relatively high penetrative. When characters, etc. are printed on recording paper, the black ink and the processing solution thus coalesce on the recording paper, and the penetrability of the mixed solution becomes a given level or higher, and this permits to accelerate the penetration and fixation.

摘要： A liquid discharge method for discharging liquid by use of a liquid discharge head provided with liquid discharge nozzles having a plurality of electrothermal converting members capable of forming bubbles for discharging a liquid droplets comprises the step of using a driving condition in a range where the discharge speed of droplets is made substantially constant, while the amount of droplet is made changeable with the timing difference of driving when droplets are discharged by driving a plurality of the electrothermal converting members one after another. With the adoption of the method thus structured, high quality prints can be obtained without deviation of impact positions irrespective of the dot diameters, larger or smaller, for a significant enhancement of image representation.

摘要： Ink-jet printing with fixing ability, while maintaining printing qualities such as OD and sharpness at high levels, can be achieved by using an ink containing a self-dispersing pigment as a coloring material without using a dispersant and a treating liquid for insolubilizing the coloring material. Benalkonium chloride (G50) having one cationic group in the molecule is used as the insolubilizing agent in the treating liquid. As a result, the cationic group is completely bonded to the anionic group of the pigment particle, thereby producing a cohesive force between pigment particles.
