reduced (i.e., foreshortened) in the subscanning direction, which
also results in elongation in the main scanning direction.
Column 7, line 62 through column 8, line 2; column 9, line 68
through column 10, line 4; and column 10, lines 32-34. Thus,
Umeda elongates a writing dot in the first scanning direction and
foreshortens it in the second scanning direction as recited.
This is done for the express purpose of limiting line thickening
or modular transfer function error in the subscanning (second)
direction. Column 7, lines 49-67; column 10, lines 4-5 and
32-34. Limiting the thickness of the printed dots in the
subscanning direction also limits the printed dot overlap shown
in Figures 12(c) and (d). Because Umeda’s reduction of the
writing spot size in the subscanning direction limits visible
scan dot overlap in the subscanning direction, Umeda fully
anticipates Claim 13.
Furthermore, in connection with the fourth embodiment (Fig.
15), Umeda explains that the spot size can be increased in
subscanning direction, thereby resulting in elongation in the
main scanning direction. Column 10, lines 51-54. This also
satisfies claim 13.
