Daryl, I'm not sure if this is applicable to your circumstance, but thought
it worth mentioning. A point to note when working with bitmap images is that
because they are one bit images their resolution should always match that of
the output device. This ensures they print at the best possible quality.

The dpi for printing will depend on the printer. If you have a 600dpi
printer and want to make use of its full capability, prepare your work at
600dpi. Any more will be a waste.
If you're happy to use a lower resolution in order to reduce file sizes,
then for preference and in principle you should choose a submultiple, like
300, 200,  etc. to avoid moiré effects. In practice, usually you can't see
the moiré effects anyway in these cases because after all, 600dpi is pretty
fine, but it's nice to know one is doing it 'right'.
