Abstract
An ink-jet printing method for painting an image on a recording medium uses ink-jet heads equal in number to the least common multiple of numbers of rows or columns of two different sizes of dot matrices. The ink-jet heads are disposed in side-by-side arrangement so as to deposit ink dots on dot lines adjacent one another. When a dot matrix having m rows and k columns for a single picture element is selectively used, ink-jet heads are so classified into several sub-groups of m ink-jet heads as to deposit ink dots on several scanning lines each of which comprises m dot lines. On the other hand, if the ink-jet heads are classified into several sub-groups of n ink-jet heads each, then they deposit ink dots on several scanning lines each of which comprises n dot lines when a dot matrix having n rows and l columns for a single picture element is selectively used.
