Abstract
An ink jet head (47) is moved relative to a recording surface (11). Print signals are applied to the ink jet head (47) from a computer or the like (22) causing the ink jet head (47) to eject ink onto the recording surface (11). The amount of ink ejected and thereby the density of printing correspond to the magnitudes of the print signals. The ejection velocity of the ejected ink increases with the magnitudes of the print signals. The timing of ink ejection is adjusted in accordance with the magnitudes of the print signals in such a manner that the ejected ink is incident on the printing surface (11) at a same position at all velocities of ink ejection.
