PURPOSE:To always perform visually good recording not causing a white stripe or high density joint like stripe between lines even in the recording of an image having graduation properties by superposing first recording and second recording one upon another so that density is made lower than that of other region in the adjacent region of them. CONSTITUTION:In the overlap of recording dots, the terminal dot jm of an Ai line and the head dot j1 of an Ai+1 line are overlapped to set the recording density of both dots to 1/2 that of other dots. For example, in the case of shift, quantity S=0, the recording deNsity of the mutually overlapped dots jm, j1 is 1/2 the recording density of other dots not overlapped each other and, therefore, at the overlapped place, sum total recording density is same to other density and no recording density difference is generated. In the case of S=+1, dots jm-1, j1 are overlapped and the sum total recording density is only 1.5 times the recording density of other dots and, since an overlap position is expanded to a position of two dots, it is inconspicuous. |
