PURPOSE:To substantially prevent the generation of a recording error in reciprocal recording, by not only substantially shifting the impact point of a recording liquid on an object to be recorded by integer-times of a dot pitch but also differentiating the emitting timings of the recording liquid in forward and backward paths. CONSTITUTION:In a liquid jet recording apparatus for performing reciprocal recroding, the relation of the distance L between an ink jet head 2 and recording paper P, the absolute value V of the moving speed of the head 2 and the absolute value (v) of an ink emitting speed is set so that the shift of the impact points of ink emitted at the same position on recording paper in the forward and backward paths in the reciprocal movement of the head 2 is substantially n- times [wherein (n) is an integer] of a dot pitch. Further, by preliminarily adjusting the emitting timing of the ink in the forward and backward paths by counting the same over n-dots, the recording error in the reciprocal movement of the head is eliminated or markedly reduced unless the above-mentioned distance L is especially made small. |
