Not necessarily bad. Toner transfer must be done just right to be
successful, as must photo-resist and anything else. We're just
figuring out what "just right" is.
Printing puts down a -lot- less ink than brushing a blob on will do.

I suppose, however it just won't be the same. The ink will have longer
to dry on the way to the surface and won't be the same density.
My board is still cooking the ink dry at about 180 to 200F in the
toaster oven. Not likely to find time to test etch until tomorrow.
Definitely can't use the foam brush method of etching. Even after a
day of drying, I can scratch the ink off with a fingernail.
