ABSTRACT:
When a multiple-ink-jet printer or plotter prints one array of ink dots by one printing cycle or scan, the spacing between the lowermost row or the leftmost column of one array of ink dots printed previously and the uppermost row or the rightmost column of the adjacent array of ink dots printed next becomes too wide or too short, thus leaving a blank row or column or a black line segment due to the overlapping of the ink dots. In order to overcome this problem, the outermost rows or columns of the adjacent ink dot arrays are overlapped in such a way that the ink dots printed by the previous printing cycle or scan are interlaced with the ink dots printed by the next printing cycle or scan, whereby the boundaries between the adjacent ink dot arrays may be rendered less noticeable.
