<p>In a continuous jet type ink jet recording apparatus, a delay time corresponding to a delay by the air resistance which varies in response to the dot size is provided to each dot. A delay pulse generator DPG delays an encoder clock signal fE (dot recording clock signal) by an integral number of times the period of a disintegrating frequency signal fd in response to pixel data DP read out in synchronism with the encoder clock signal fE from a line buffer LB, and outputs an encoder clock signal fE*. A pixel buffer PB stores the pixel data DP in a first-in first-out fashion in synchronism with the encoder clock signal fE and outputs the pixel data DP in synchronism with the encoder clock signal fE*. A pulse width modulator PWM modulates the pixel data DP into a charge control signal SC* of a pulse width corresponding to a value of the pixel data DP in synchronism with the encoder clock signal fE*. Consequently, a delay time corresponding to the pixel data DP is provided in advance to a recording ink drop train, and the delay by the air resistance is compensated for. <IMAGE></p> |
