  Just etch through it. Since the fine layer isn't enough to block the etchant, it undercuts the individual grains of toner and removes the copper anyway.

  Or are you getting a solid coating on the bare copper? 

  You can use a little bit of air or tapping to knock off excess toner, although that removes ANY toner, I find it doesn't remove much from the inked areas. I just let it sit for a while so the toner in the ink has a chance to really settle in, then I tap it upside down and sometimes blow on it a bit with canned air. Once in a while I have to manually clear areas between pads that are too close to each other by scraping off the toner with a sharp blade or probe.

  Another issue is humidity... and static... there may be a fine balance between the two.

  Please let us know how it goes and what you find works for you?

  I am unfamiliar with the hybrid method. I think I understand the procedure, at least to the extent that it has been explained in these posts ... but what is/are the advantage(s)?

Does this method provide better resolution than toner transfer? Or easier to
do than toner transfer? (The reason I'm asking it this way is that what I am
using is ... you guessed it ... toner transfer!)
