摘要： A printer comprises a first head which has first nozzles, a second head which has second nozzles each having a nozzle diameter larger than that of the first nozzle, and an ink cartridge which stores an ink to be supplied to the first and second heads. The first head is directly connected to the ink cartridge by means of a tube. The second head is connected to the first head by means of a tube, and thus the second head is connected to the ink cartridge via the first head. Accordingly, it is possible to shorten the tubes by connecting the ink cartridge and the two heads in series. Further, it is possible to decrease the frequency of the recovery operation by arranging, on the downstream side in the liquid supply direction, the head in which the jetting failure is hardly caused.

摘要： The present disclosure relates to an ink-jet ink set which, in spite of using a black ink including a black pigment, may display desirable storage stability and/or may form printed matter (e.g., images) with desirable rub fastness against a plain paper surface, color balance after fading (fading stability), and/or water resistance. An ink set may include a yellow dye ink including a yellow dye, a magenta dye ink including a magenta dye, a cyan dye ink including a cyan dye and a black ink, the black ink including a black pigment and a yellow dye, a magenta dye, and a cyan dye. A black ink may have a weight ratio of the amount of the black pigment to the total amount of the yellow dye, the magenta dye, and the cyan dye of from about 95/5 to about 70/30.

摘要： A water base ink for ink-jet recording contains self-dispersible carbon black as a coloring agent. The total content of an organic acid having a number of carbon or carbons of 1 to 6 and a salt of the organic acid is not more than 400 ppm. The organic acid having a number of carbon or carbons of 1 to 6 includes monocarboxylic acid, dicarboxylic acid and oxy acid, and the salt of the organic acid includes salts of these acids. When the water base ink is used in an ink-jet recording apparatus, the discharge stability of the ink is improved.

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 long-term storage properties 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 ozone resistance 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 water base ink set for ink-jet recording includes a water base ink which contains an acid dye, and a water base ink which contains a basic dye. The water base ink contains a polymer which has an average molecular weight of 3,000 to 20,000 and which is represented by the following formula (1): wherein X represents H or COONa, and Y represents H, COONa, SO3Na, or CH2OR in the formula (1). R represents a substituted group having SO3Na with carbon atom or atoms of a number of 1 to 5. When the ink containing the acid dye and the ink containing the basic dye are mixed with each other, then the head discharge section is prevented from any clog-up, and it is possible to perform the stable jetting operation.
