ABSTRACT:
In a recording apparatus, spreading of ink droplets is avoided, and mixing of adjacent ink droplets is prevented so as to improve an image quality of a recorded image, and to increase resolution of this recorded image. In a recording apparatus for jetting ink droplets corresponding to recording data from a recording head to thereby adhere the ink droplets in a dot form onto a recorded member, there are provided: a data input unit for obtaining recording data in such a manner that no ink droplet is jetted to a specific dot existing in a preselected interval in such a region that a large number of recording dots are formed having density higher than at least predetermined density, whereas the ink droplets are jetted to dots other than said specific dot; a signal converting unit for converting this recording data into a recording head drive signal; and a drive unit for driving a recording head by modulating this converted signal. Also, while improving image qualities by employing the carrier jet type printer, the character and the image can be separately formed in the character region and the image region in response to the recording data.
