PURPOSE: To improve the fixing properties of ink, inhibit the bleeding of ink and enhance discharge stability by adding at least, a water-soluble organic solvent to a diluent, in a printer which records data by discharging the diluent to a recording medium after mixing the estimated quantities of ink and the diluent. CONSTITUTION: An orifice plate 1 is formed as a laminated plate, a first and a second feed orifice 21, 22 are provided on a first plate 11 (1a), and a nozzle 23 which discharges a mixture of two different types of liquid to be supplied from the first and the second feed orifice 21, 22, is formed on a second plate 12 (1b). A diluent should contain at least, a water-soluble organic diluent, and contain aliphatic monohydric alcohol. The preferable content of this monohydric alcohol is about 5 to 50wt.%. If the content is proper, the monohydric alcohol makes the bleeding uniform, increases the permeability of the mixture into a recording sheet and the evaporative capability of the mixture. Thus an image is better fixed and is of a high quality. |
