Why text looks "Fatter" when converted to outlines:

"Thomas Phinney, Program Manager Fonts & Core Technologies from Adobe
Systems tell about why the text fattens when you convert to outlines.
TWO things happen when you outline fonts:
- loss of hinting
- change in fill algorithm
The loss of hinting makes certain features potentially inconsistent.
For example, letter strokes that you expect to be the same width might
turn out to be different widths depending on how they fall on the grid
of the output device. Slight differences can get magnified
unexpectedly, like rounded letters going below the baseline. This
happens because the information that makes the outlines round
consistently to the pixel grid has been lost.
The change in the fill algorithm combines with the lack of hinting to
make the letters look fatter. Font rasterizing uses a fill algorithm
that turns on a pixel only when the center of the pixel is within the
glyph outline (center-scan). Graphics rasterizing uses a fill
algorithm that turns on a pixel when any part of the pixel is within
the graphic outline (overscan). Given that the outline is no longer
being rounded to pixel boundaries at key points, the rendering will
generally be at least one pixel thicker, occasionally two.
Of course, how much difference this makes depends on the size and
style of the type, and especially on the resolution of the output
device. At 2400 dpi with typical text sizes, the effect is pretty
subtle. At 600 dpi with 6 point text, the effect is quite obvious."

Co-worker is trying to create outlines of a map file to send to
print. the font sizes are very small so when creating to outlines,
the fonts and lines in the maps appear to be way to bold to read when
printed.
How do we create outlines and still have it come out crisp, clean and
legible?
thanks,
Nora
