Homebrew PCBs

Hi,
Like I said in my first posting, I'm only just starting to play with this method but the attraction to me was as I understand it, special pigment based ink's are not required and the resist layer produced should be tougher than the pigment based ink alone!

  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)?

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.
