I had the same kind of problem here. I got round it by misting fine coats of Micro scale decal film. Real fine so it is almost dry when it hits the surface. You don't want to really wet the ink. If you can discipline yourself to build up a coat that way, (My usual downfall), once you get a few misted coats dry, you can build it up from there if you don't spray so much it re-dissolves the film down to the ink. Printer ink can be a pain.
