ABSTRACT:
A printing method for performing enlargement printing of one continuous line by simultaneously shifting a plurality of printing heads by a shifting magnitude. The shifting magnitude of the printing heads is set to be greater than a shifting magnitude utilized in standard printing. Dividing points for shifting traces of each of the printing heads are set such that the shifting traces of adjacent printing heads partially overlap one another. Divided printing zones are established between the dividing points, and the printing timing of the printing heads is controlled for performing the enlargement printing of the one continuous line. Additionally, a printing method for performing reduction printing of one continuous line is performed by setting a shifting magnitude of the printing heads to be equal to that used in standard printing. Divided printing zones are established to be printed by at least two printing heads in a non-overlapping manner. The printing timing of the respective printing heads is controlled for performing a reduced printing of the one continuous line.
