摘要:
An ink-jet recording apparatus is provided which includes an ink-jet head having a plurality of ink chambers and a common ink chamber which communicates with each of the plurality of ink chambers to supply ink to the plurality of ink chambers, the ink-jet head maintaining the plurality of ink chambers at a negative pressure in image recording, selecting one of the plurality of ink chambers on the basis of printing data and causing change in volume of the selected ink chamber, and thereby performing image recording by discharging the ink from a nozzle, and a pressure section which applies a positive pressure to the plurality of ink chambers when the ink-jet head is in a left state, the positive pressure being a pressure at which the ink is not discharged from the nozzle.

摘要:
An image printing apparatus comprises a storage section and a control section. The storage section stores an absorbing speed information in a storage area, the absorption speed information is a measured speed at which a recording medium used for a printing process absorbs an ink used for the printing process. And the control section controls an ink head so as to perform first dot recording which records a plurality of dots on the recording medium by a pitch of an ink ejection opening of the ink head, and moves the recording medium relatively with the ink head and controls the ink head so as to perform second dot recording which records a plurality of dots between a plurality of dots recorded by first dot recording, in accordance with a print interval time determined based on the absorption speed information stored in the storage section.
摘要:
An ink-jet head includes a nozzle array including plural nozzles. The nozzle array has a first nozzle group arranged in the center thereof and second nozzle groups arranged further on outer sides than the first nozzle group. Inter-nozzle pitches of the second nozzle groups are larger than inter-nozzle pitches of the first nozzle group. A direction in which nozzles of the second nozzle group eject an ink and a direction in which nozzles of the first nozzle group eject the ink are different.
