Abstract
Two lines extending in the main scanning direction build a set of lines (L , L ) each of which is formed by a plurality of dots. Assignment is alternately executed to preceding scanning and subsequent scanning so as to allow each of the lines (L , L ) formed by a number of pixels (P , P , P , P , P , P , P , P , - - - ) to extend along a snake movement-like route. Thus, dots located adjacent to each other in the auxiliary scanning direction are not formed by same scanning, and a quantity of ink spreading on a recording medium without penetration of the ink through the latter can be reduced. Consequently, there few arises stripe and fluctuation in density, whereby an excellent quality of image having sharp edge portions can be obtained without any occurrence of a problem attributable to the presence of unfixed ink.
