摘要:
The invention relates to an ink-jet recording apparatus having a nozzle provided on a nozzle face of an inkjet head and a cleaning device for cleaning the nozzle face. The cleaning device contains a gas with a solubility in water lower than that of air in water.
摘要:
A water-based ink for ink-jet recording includes a coloring agent, water, and a water-soluble organic solvent. The coloring agent includes the following dye (1) and dye (2). The water-based ink is good in clearness, color development, and preservation stability as well as good in toughness of a recording material recorded using the water-based ink. Dye (1): dye represented by the following general formula (1) Dye (2): at least one dye selected from the group consisting of C. I. Direct Yellow 86, C. I. Direct Yellow 132, C. I. Direct Yellow 142, and C. I. Direct Yellow 173.

Provided is a water-based ink set for ink-jet recording for reducing bleeding between a black (Bk) ink and a yellow (Y) ink and for reducing color unevenness in a portion formed by color mixing of color inks. The water-based ink set for ink-jet recording includes at least a Bk ink, a Y ink, a magenta (M) ink and a cyan (C) ink. In this configuration, the following relationships are satisfied: (1) σ1000Bk≧35 mN/m; (2) |σ30Y−σ30Bk|≦5 mN/m; (3) σ30M≧30 mN/m, σ30C≧30 mN/m; (4) σ30Y>σ30M, σ30Y>σ30C; and (5) σ30Y+σ30M≦93 mN/m, σ30Y+σ30C≦93 mN/m, wherein σ30Bk, σ30Y, σ30M and σ30C are dynamic surface tensions of the Bk ink, the Y ink, the M ink and the C ink, respectively, at a lifetime of 30 ms as measured by a maximum bubble pressure method at a measurement temperature of 25° C., and σ1000Bk is a dynamic surface tension of the black ink at a lifetime of 1,000 ms as measured by the maximum bubble pressure method at a measurement temperature of 25° C.
