    摘要: To prevent an ink blurring on the recording medium, the ink jet recording apparatus for ejecting ink droplets onto the recording medium to record an image includes a plurality of recording heads, each having a plurality of ejecting ports and ejecting different inks; a data storage device for storing printing data and non-printing data for each of the recording heads; a boundary detector for detecting a boundary between the printing data and the non printing data of one of the recording heads in accordance with the printing data stored in the storage device; and a judging an adjusting device for judging whether printing data of other heads continues for more than a predetermined number of dots at the boundary detected by the boundary detector; and a thinning device for converting some of the printing data of the other heads to non printing data when the judging means determines that the printing data of the other heads continues for more than the predetermined number of dots.

    摘要: A recording apparatus includes a plurality of recording elements a plurality of drive ICs, in which a plurality of drive signal lines containing a signal line for an image data signal and a signal line for a transfer clock which transfers the image data signal are connected in cascade. Each drive IC supplies a recording current selectively to the recording elements in correspondence to the image data signal. A transfer clock control circuit, which is located at an input part of the transfer clock in the recording apparatus, controls a duty of the transfer clock supplied to the drive ICs so that a duty ratio of the transfer clock at the final stage of the plurality of drive ICs is enough to transfer the image data signal.
