I don't think they can be easily removed other than by scraping, sorry. There are chemicals, but you won't want to use them, and they'll attack the mask as well, most likely. OTOH, you could cover up the bad printing with a block and then print over that. Silk screening is one method. If you have, say, 100 multilayer boards, it can be easily subcontracted, and might save you some money. If you have a few cheap boards, the fixed costs will negate any savings.
