摘要： In an ink-jet recording apparatus, insoluble materials originating from rubber members employed in an ink passage are prevented from precipitating into a preservation solution or a water-based ink filled into the ink passage. The ink-jet recording apparatus in which the preservation solution or a water-based ink is filled into the ink passage, is configured such that a rubber member employed in the ink passage is formed of a rubber not containing a lubricant.

摘要： The ink-jet recording apparatus has an ink passage into which a water-based ink or a preservation solution is filled. The ink passage employs a rubber member formed from a rubber in which a butyl rubber polymer serving as a base polymer, zinc oxide serving as a vulcanization agent and a thiazole-based compound serving as a vulcanization accelerator are employed. The water-based ink includes at least a coloring agent, water and a glycol ether, an amount of the glycol ether being about 5 wt. % to about 10 wt. % with respect to the total weight of the water-based ink. The preservation solution includes at least water and a glycol ether, an amount of the glycol ether being about 5 wt. % to about 10 wt. % with respect to the total weight of the preservation solution.

摘要： A printer comprises a fixed line type first head, a serial type second head, an ink cartridge which stores an ink to be supplied to the first and second heads, a first cap which is to be installed to the first head, and a second cap which is to be installed to the second head. The ink cartridge and the first and second heads are connected in series in this order by using tubes. Accordingly, it is possible to shorten the lengths of the tubes. The serial type head, in which the drying is hardly caused from a nozzle and the influence is exerted to a small extent on the jetting performance when any viscosity-increased liquid and/or bubbles is/are supplied, is arranged on the downstream side. Accordingly, it is possible to decrease the frequency of the recovery operation.

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 form printed matter (e.g., images) with desirable water resistance and/or color balance after fading (fading stability) and/or ink-jet ink sets with desirable storage stability. 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. A black ink may include a black pigment, a yellow dye, a magenta dye and a cyan dye. A black ink may have a weight ratio of an amount of a black pigment to a total amount of the yellow dye, the magenta dye, and the cyan dye of from about 5/95 to less than about 30/70 (e.g., from about 5/95 to about 30 (but not inclusive of 30)/70).

摘要： The ink-jet recording apparatus has an ink passage into which a water based ink or a preservation solution is filled. The ink passage is formed from a rubber employing organic peroxide and zinc oxide as a vulcanization agent. The ink has a dynamic surface tension at a lifetime of 100 ms of about 35 mN/m to about 45 mN/m as measured by means of a maximum bubble pressure method at a measurement temperature of 25° C. The preservation solution has a dynamic surface tension at a lifetime of 100 ms of about 30 mN/m to about 35 mN/m as measured by means of a maximum bubble pressure method at a measurement temperature of 25° C.
