Homebrew PCBs

Also, don't forget that Volkan had excellent results with a 'substitute'
ink, not the original Durabrite.

I agree.  After that message, I went back out to the shop and put 
some ink on a PCB to let air dry.  After about an hour or so (don't 
know the exact amount of time), I rubbed my finger over it and some 
of the ink came off on my finger.  

I am going to leave it overnight and see if any more rubs off 
tomorrow. 

I did hit the test sample that I etched with the hot air gun.  I 
would have expected that to "Cure" the ink.  I did get the board hot 
enough where it was very uncomfortable to hold by it's edges.  So, I 
would have thought the ink was cured by that point.

I won't be around much tomorrow so I can't do too much more.  Over 
the week though I am going to try some other things if the ink 
doesn't dry up in the cartridge.  

At this point though, I know the ink will act as a resist. I also 
know it won't bead up on the copper.  Like you guys, I suspect that 
proper drying is key.  So, that is what I am going to focus on as I 
have time - getting the ink to dry, perferably quickly.
