The trick is hairspray!
By no means do I suggest you now run and go all Picasso on pieces of your wardrobe just to test this out, but if you're struggling to get the stain out next time, or haven't even tried anything else yet, grab a can and spray it on the offending ink, You need to pretty much drown it, and it should actually fade on the spot. Then chuck it into the wash to get rid of that crispy hairspray! Wash, dry, iron as normal afterwards but if it has worked, you will know before you even put it in the wash.
