anyone know what i can do to cover ball point ink under acrylic paint??
i used ball point in under a portion of a canvas on an underpainting.
the pen ink bleeds thru the underpainting and right thru 2 more coats of gesso.
any idea what i can put over the pen ink so it won't transmigrate thru the acrylic paint?????

This is one of the reasons I hate ballpoints for finished work. The other is the total lack of archival quality.
You basically have two options, neither of which is pretty. The first is to strip the paint layers back to the underpainting, and then seal the ballpoint drawing with polyurethane or some kind of lacquer sealer before proceeding to the next step of the painting. I'd give the sealer extra time to dry, and then go over it with a wet cloth to remove any ink that migrated before the seal coat had dried completely. Then you should be okay to paint.
The better method-- since you're stripping back to the underpainting, anyway-- is to use isopropyl alcohol to clean all of the ink off of the support, followed by a wipe-down with clean water (just so you aren't leaving any chemical residue behind); if you need to re-draw the image, use graphite or charcoal, and seal it with either fixative, an acrylic sealer or touch-up varnish to keep the lines from smudging on you.
If you're dead-set against doing that much work, or you think it will destroy the painting, or whatever, the only other thing you can do is keep applying gesso until there isn't enough ink in the layer below to migrate up, anymore. That doesn't guarantee that it won't migrate upwards, eventually, and you may wind up with a gesso layer 1/8" thick (I speak from experience, unfortunately), but it might work.
Finally, let me add this unfortunate lesson, hard-learned from tragic personal experience, lol: there is no such thing as water-proof ink. The manufacturers are evil, evil liars, the lot of them. Even "waterproof" india ink will smear and migrate if given enough water to swim in. I say this after spending a couple of years working with watercolor, ink and colored pencil and watching many a beautiful piece turn to mud because of a misplaced dollop of H2O. But anything you can buy at your local OfficeMax is almost guaranteed to cause problems when used in conjunction with any wet media.
Hope this helps. Good luck!
