NOTE:
As shown in the sample, gaps between passes are sometimes created
in different directions among patterns.
This unexpected change in direction is caused by an ink jet printer-
specific reason, which is an ink jet printer inevitably performs a
periodical cleaning specified by the flashing timer even during Bi-D
pattern printing, so that the printing direction suddenly changes.
