摘要： An ink jet printing apparatus includes an ink jet head having a plurality of nozzles for respectively ejecting ink drops, a plurality of ink chambers communicating with the nozzles, and a plurality of electromechanical conversion elements corresponding to the respective nozzles. The volume of the ink chamber of the non-drive channel is increased by the influence of the drive channel adjacent thereto, and thereby undesired ejection of the ink drop occurs. To solve this problem, a drive energy set for ejecting the ink drop is applied to the piezoelectric elements of the drive chambers n−1, n+1 and a reduced drive energy set for not ejecting the ink drops is applied to the piezoelectric element of the non-drive channel n.

摘要： An ink jet printing head includes: a plurality of piezoelectric actuators arranged in rows on a substrate, each row including first piezoelectric elements and second piezoelectric elements which are alternately arrayed along the row, the first piezoelectric elements being actuatable to apply a compressive force to ink in accordance with print signals, the second piezoelectric elements being fixed and not actuated; and an ink chamber unit which includes ink chambers located above the first piezoelectric elements and containing ink. The ink chamber unit includes: an oscillation plate including diaphragm portions which are connected to the first piezoelectric elements and independently deformable in a direction perpendicular to the substrate by the first piezoelectric elements when actuated; and a nozzle plate which includes nozzles being located above the diaphragm portions and opened to the ink chambers, so that ink drops are respectively forced out from the nozzles when the first piezoelectric elements are actuated.

摘要： An image processing apparatus is disclosed. The image processing apparatus includes a color conversion processing unit which obtains CMY data from input color space coordinate data of image data, and an output data generating unit which generates output data by forming CMYK data by using a result output from a color conversion processing section.
