PROBLEM TO BE SOLVED: To prevent dots to be recorded from continuing and decrease deterioration of images, by making a recording head record with a smaller count of dots than a maximum count of recordable dots at least when a density data shows a maximum value. SOLUTION: At the time of printing, a control part 210 carries out a masking process to a density signal from a host or the like, and performs an undercolor removal.black generation process. When a gamma correction is made then, it is detected whether the density signal includes pixel data of a maximum density value. When the detection result is YES, the maximum density value is changed to a value decreased by, e.g. 2%. Gamma corrected image data are binarized and output to a recording head 1 via a head driver 211. The value decreased from the maximum density value is preferably 97-99% depending on a resolution at the time of recording, a kind of ink, a record system, a kind of a recording medium and the like conditions. A count of dots is suitably reduced in accordance with the conditions within the range of the value, so that good images can be obtained. |
