@ Hohum: the method I use for ink bleeding actually depends upon you having merged them all onto one layer (you can do it still separate, but it makes a LOT of extra layers). Basically you name that merged layer Ink, and duplicate it a few times, which makes names like "Ink Copy" etc. If I'm talking about "inking" something, I mean using the Ink tool. If I'm talking about "all the ink" I mean exactly what you just described; all of the black lines/features etc. If your labels are hard to read afterward, you may be forgetting to leave the original ink layer alone (albeit changing opacity/mode); it should still be there showing where the original pen marks were, as Jugg described.
