The flowing-path plate has a plurality of nozzle-communicating chambers and a plurality of elongated pressure-chambers. The plurality of nozzle-communicating chambers respectively communicate with the plurality of nozzles, the plurality of pressure-chambers respectively communicate with the plurality of nozzle-communicating chambers, and the plurality of pressure-chambers are open to a side away from the nozzle plate. A vibrating plate commonly seals the open surfaces of the plurality of pressure-chambers of the flowing-path plate, and a plurality of pressure-generating units respectively changes pressures of liquid in the respective pressure-chambers. The plurality of nozzles are aligned on a line segment, and at least one of the pressure-chambers communicating with at least one of the nozzles in the vicinity of an end of the line segment is formed so as to have a shorter length than at least one of the pressure-chambers communicating with at least one of the nozzles away from the end of the line segment.

    摘要： An apparatus for driving an ink jet record head, in which a pressure generating element and an opening is provided for each of a plurality of nozzles so as to cause an ink droplet to spout from the opening. The apparatus includes a driving signal generation unit that generates a driving signal, which includes a first driving pulse for causing a first ink droplet to spout from a nozzle and a second driving pulse for causing a second ink droplet to spout from the nozzle that is greater in size than the first ink droplet. Also included is a dot creation unit configured to select both the first driving pulse and the second driving pulse in one recording period corresponding to the recording of one pixel so as to create a larger dot than dots formed by the first and second ink droplets, and an element driving unit that drives the pressure generating element in response to the selected driving pulses.

    摘要： In monochrome printing mode, a first correction value is set for correcting printing positional deviation between ink droplets printed during forward and reverse main scanning passes. In color printing mode, a second correction value is set for correcting printing positional deviation between ink droplets printed during forward and reverse main scanning passes. An adjustment value is determined for reducing printing positional deviation during forward and reverse main scanning passes. For this, in monochrome printing mode the first correction value is used as an adjustment value, and in color printing mode at least a second correction value is used to determine an adjustment value. Following this, the adjustment value is used to adjust printing positions during forward and reverse main scanning passes.

    摘要： Image quality is improved by correcting printing position deviation arising between forward and reverse passes in the main scanning direction during bidirectional printing. An adjustment value is prepared with respect to at least one type of specific target dots other than those dots having the highest density out of the plural types of dots. Printing positions during forward and reverse main scanning passes are adjusted with the adjustment value to reduce printing positional deviation between forward and reverse main scanning passes.
