I've never used PnP, but i strongly doubt it can increase the resolution.
My experiments have shown that you can make traces down to 6.66 mil  
reliably with inkjet paper, but 3.33mil and smaller won't come out right  
due to underetching. I don't think this is a resist question, i suspect it  
can only be overcome with a better etching system, although the resist  
might also have to do with it. See

for a test i did a while back.

P.S.: Better get a old clothes iron, some acetone for yourself, and a  
stock of spare staedtler pens to surrender as long as you still can ;-)
