drydown can be reduced by lowering the wattage of your viewing light in your
darkroom. many people use bulb too powerfull. try 25-40 watts, keep it 6-10
feet away from your viewing area.

No clue why it happens, but it seems to.  Somewhere recently I read that
drydown was a bunch of hogwash; it had more to do with surface reflection
or something like that and the prink didn't actually darken.  Anyway, put
wet and dry strips from the same print side by side and see it yourself.
It will vary from one paper to another and for different surface types as
well.  The water has some effect on surface reflection, but I can't give
you more than that.  It bugs me when I leave what look like very nice
prints on a fibreglass screen to dry -- they looked great after washing,
but look flat and muddy when dry.
