摘要： An ink for ink-jet recording of the present invention includes a dispersion of a pigment, and an ink solvent containing a water-soluble organic solvent and glycol ether. The ink is prepared such that an Rf value, which represents a rate of flow of the pigment obtained when the pigment dispersion is developed with the ink solvent by means of paper chromatography, is not more than 0.5. The ink has a fast permeation speed, and hence the feathering and the bleeding are avoided.

摘要： An ink set for ink-jet recording is provided defined by an evaluation indicator approximately corresponding to an evaluation sensed by human eyes without relying on a color difference (ΔE) or an optical density difference (ΔOD) at the time of evaluating a long-term storage stability of the ink set for ink-jet recording. In the ink set for ink-jet recording which contains a yellow ink, a magenta ink and a cyan ink, values of hue angle change (Δh), between before and after lightfastness tests, of print regions corresponding to respective inks formed on glossy paper by using the yellow ink, the magenta ink and the cyan ink are not more than about 3° for the yellow ink, not more than about 2° for the magenta ink, and not more than about 6° for the cyan ink.

摘要： A printer includes a first head in which first nozzles are formed, a second head in which second nozzles located at a higher position than the first nozzle are formed, and an ink cartridge positioned at a lower position than the first and second nozzles. Moreover, the first head is connected to the ink cartridge via a tube, and the second head is connected to the first head via a tube. Accordingly, the second head is connected to the ink cartridge via the first head. It is possible to shorten the tubes by connecting serially the ink cartridge and the two heads, and to prevent from breaking simultaneously a meniscus in the nozzles of both the heads located at different height positions.
