    • In a method and printing device, a deviation from a predetermined desired pitch that occurs between at least two points of at least one print image in a print direction is reduced. In a printing step, the at least one print image is generated on a substrate with at least one print head of the printing device with a relative movement between the at least print head and the substrate. In a determination step preceding the printing step, an initial deviation from a desired pitch between the two points is determined first and correction information to reduce the deviation is determined from the determined initial deviation. In the printing step, control signals for the at least one print head are generated depending on the correction information to generate the at least one print image. A variable delay of at least one of the control signals is predetermined by the correction information.
    • 在方法和打印装置中,减少了在打印方向上至少一个打印图像的至少两个点之间发生的预定期望间距的偏差。 在打印步骤中,至少一个打印图像在具有打印装置的至少一个打印头的基板上产生,该打印头在至少打印头和基板之间具有相对运动。 在打印步骤之前的确定步骤中,首先确定与两点之间的期望间距的初始偏差,并根据所确定的初始偏差确定用于减少偏差的校正信息。 在打印步骤中,根据校正信息产生用于至少一个打印头的控制信号以产生至少一个打印图像。 至少一个控制信号的可变延迟由校正信息预先确定。
