摘要： An ink jet head is fed in a main-scan direction to record one line on a recording paper. Thereafter, the recording paper is fed in a sub-scan direction for one line. A corrected feeding amount A is calculated by adding a correction value C1 to a basic feeding amount B. The correction value C1 is determined by a formula, C1=2·D·(R−½), wherein p represents an interval between dots recorded on recording paper in the sub-scan direction, and k represents a range of unevenness in the feeding amount caused by structural factors of sub-scan feeding means. For example, D=(p−k)/2. R is a random number in a range between 0 and 1. Gradation unevenness and/or black and white streaks caused by periodical feeding unevenness become inconspicuous since the correction value C1 is changed on a random basis.
摘要翻译：喷墨头沿主扫描方向进给，在记录纸上记录一条线。此后，记录纸沿副扫描方向进给一行。通过将校正值C 1添加到基本供给量B来计算校正进给量A.校正值C 1由公式C 1 = 2·D（R-½）确定，其中p表示间隔在副扫描方向上记录在记录纸上的点之间，k表示由副扫描进给装置的结构因素引起的进给量的不均匀范围。例如，D =（p-k）/ 2。 R是在0和1之间的范围内的随机数。由于校正值C 1随机地改变，所以由周期性进给不均匀引起的渐变不均匀性和/或黑白条纹变得不明显。
