Homebrew PCBs

This is probably something in the 10% range. What I failed to clearly  
express is that is only vertical (i.e. along the length of the paper)  
horizontally, it seems pretty perfect (I can only hold a draft print  
on normal paper above it with bright light - they line up well across  
but not up and down. Which is why I assume it's due to drag.

Plus the PCB's I have made *do* line up with the iPod connector which  
is a series of 15, 16mil traces, which is very obviously wrong on this  
one. (Though, I was almost certainly printing it at 90° to the current  
arrangement in the past)

I just got my other half to check the stock's weight and it's 210 gsm,  
so the total was 290, which is 3.6 x the standard weight here ... HP  
sez that 158 is the max (42lbs) so I was almost double.

Didn't somebody say they were using pages out of some catalogue?
